A Guide to QR Codes

The digital age is changing the way business is conducted for everyone. New technology is always in development and being implemented in different industries across the globe. One such development is quick response codes, otherwise known as QR codes. 

Though the initial QR code system first appeared in 1994 after being developed by a company called Desso Wave, improvements have since been made to the technology. QR codes are quickly becoming a popular way to share business information with customers and employees alike. QR codes are even being used by inventory and warehouse managers as a reliable way to track products.

What Are QR Codes?

Businesses everywhere are starting to use QR codes. QR codes were initially developed as a way to store more information and provide reliable tracking for vehicles and parts. Today, these codes are used for website links, menus, phone numbers, serial tracking and even Wi-Fi passwords. Users can access this information by scanning the QR code with a capable device. 

A QR code looks and functions somewhat like a barcode. In inventory management applications, barcodes contain information pertaining to specific items. Barcode scanners read their black and white lines and translate them into information that a sales system can process. QR codes were made to be more efficient than barcodes, and there are a few key differences in how they work. 

Barcodes are much simpler and can only be read from left to right. QR codes can be read from top to bottom and left to right at angles rather than just horizontally. As a result, QR codes are easier to scan quickly. They are also able to hold more information than a standard barcode. In fact, QR codes can hold over 4000 characters of information, making them a perfect choice for those looking to store more data.

Two main types of QR codes exist currently — static and dynamic. Static QR codes hold information that can’t be changed or edited. These are usually used for special events where information doesn’t need to be changed. They’re also used to store sensitive information such as employee numbers. Dynamic codes, on the other hand, can be edited. They offer more options than static codes. These codes are also quicker to scan than static codes since they are not as compact.

One of the main reasons that QR codes have become so widespread is that they allow users to access information almost instantly. In a world where speed and convenience are highly valued, QR codes help streamline processes for all types of business. 

Are QR Codes Safe?

QR codes have many benefits, but there are potential risks involved when it comes to using these codes. QR codes are easy to use and unreadable to the human eye, making them a great tool for criminals. Malicious information can be embedded into these codes, such as malware or a malevolent URL. 

Attackers may resort to covering up public QR codes at restaurants or businesses with their flawed code, knowing that it will be nearly impossible for people to discern the difference between their code and the legitimate version. Once scanned, any code containing malware could compromise a device since any data would become vulnerable. 

Malware embedded in QR codes also has the potential to act for the user without their knowledge. It might trigger payments, send texts or make phone calls. These codes can also direct users to bad websites or URLs that are phishing for personal or financial information from unknowing people. 

Luckily, there are a few ways that you can protect yourself from these attacks: 

  • Only scan trusted codes: Firstly, always be sure to trust the code you are scanning. If someone has sent a code to you, verify the sender and contact them to make sure the code is from them. 
  • Look at the link: Attackers will often try to hide their malicious URLs with shortened links. If a link like this appears after you scan the code, reconsider opening the website.
  • Protect your devices: If you are an organization or business, it would be a good idea to have a mobile defense solution that can protect your mobile devices by blocking suspicious activity, such as phishing and unofficial downloads. This solution would act almost like a firewall and protect all your organizational or business data from becoming compromised. 
  • Go beyond password protection: Have multiple forms of authentication rather than just a simple password. This approach will make it extremely difficult for attackers to get into your devices and access vulnerable information.

In general, QR codes don’t collect personal information that can be used to identify individuals. However, they record some information and make it known to the creators. This data may include location, when the code was scanned and how often, and the type of device that scanned the code. 

QR codes also can’t be hacked. Attackers usually resort to using their own malicious codes. That said, dynamic codes pose a potential problem because they can be altered once they have been created. They can show users varying information. As a result, dynamic codes are vulnerable to being compromised. That’s why it’s important to have protection in place and be mindful of the codes you scan.

How to Create QR Codes

With a QR code, you can bolster your business and reach more people than ever before. But how do you go about making one? Fortunately, you don’t have to know how to create a QR code from scratch in order to use one. If you just need a simple QR code for a one-time occasion or for information that’s never going to change, there are online QR code generators that you can use. These work well for static codes. 

However, problems sometimes arise with these types of codes. Many of these websites only create static codes that cannot be changed, so they are somewhat limited as far as functionality. Any typos, issues or updates that need to be added will call for a whole new code, which can be a problem if the original QR code was already distributed. 

Using free online code generators also leaves you open to attackers. The site will have access to the information you embed in your code, and these free websites are vulnerable to phishing.

The good news is that there are websites you can use to create QR codes for your business that have protections in place against phishing. Some costs are associated with these websites, but they are generally worth it for the extra protection.

Creating Unique QR Code Designs

You can have a little fun when creating QR codes as well. Codes don’t have to be black and white. They can be as full of color as you’d like. If you want to create a code that fits within your branding or you need to organize codes by color for one reason or another, you can do so. You can also add graphics to help your code stand out among the rest. 

The amount of information you want to encode will also play a part in your QR code’s appearance. More information will require larger codes for scannability.

There are certain parts of the code that cannot be changed. Otherwise, the code will not work when scanned. That said, any QR code will be scannable as long as less than 30 percent of the code is covered or damaged. This window leaves many opportunities for truly unique and interesting designs.

How to Read QR Codes

Since QR codes can be read in two directions as opposed to one, mobile phones and tablets have become a popular method of scanning these codes. In 2010, the first QR code scanners were released on multiple smartphones. Afterward, tech companies started to incorporate these scanners into smartphone cameras to eliminate the need for separate QR code applications. Today, almost any modern smartphone will have a QR code scanner as part of the camera technology.

When these scanners are translating the data of the code, they’re looking at the individual parts that make up the whole code. These parts are linked together to form the whole picture, which provides users with the appropriate data. The parts of a QR code include:

  • Positioning detection markers: These markers are in the top two corners and the bottom left corner of the code. The markers help scanners quickly read the code by indicating which way the QR code is oriented. They play a part in a QR code’s ability to be scanned from multiple directions.
  • Alignment markers: These markers ensure the code is readable even if it’s on an uneven surface, where it may be curved or angled oddly. The number of these markers will change based on the size of the code.
  • Timing pattern: This pattern of alternating black and white squares informs the scanner of how large the entire matrix is. This part of the code can also assist with reading a damaged code.
  • Version information: QR codes have 40 different versions available. This information, located near the top-right, tells the scanner what version is being used.
  • Format information: This part of the code has information pertaining to the error tolerance of the QR code. It makes it easier to scan.
  • Data and error encryption keys: All of your data is included in this area, making up the majority of the code. This area also includes error correction blocks. These blocks allow up to 30 percent of the code to be covered while still being scannable.
  • Quiet zone: The quiet zone is one of the most important parts of the QR code. It’s a white square surrounding the rest of the data, and it allows the scanner to determine what is part of the QR code and not. Without the quiet zone, the scanner would not be able to read the code.

How Businesses Can Use QR Codes

Using QR codes is quicker and more efficient than using barcodes since they can be scanned from multiple angles. This speed makes QR codes a great option for businesses of all kinds. Most of the technology we already have in our pockets is capable of scanning QR codes as long as most of the code is visible and undamaged. Implementing these technologies couldn’t be easier.

Beyond letting users access your website or social media accounts with ease, QR codes also work great for inventory and warehouse management. QR codes can store far more information than a simple barcode, meaning you can include more data in your inventory. QR codes can help you track serial numbers on products. They can also include:

  • Information about where a product came from and where it has been.
  • Specific product information.
  • URLs.
  • Simple text.

QR codes streamline the process of inventory management, and their built-in security measures make errors less likely.

“The core of maturity, that I see, is starting with a unified view of inventory. I’ve got to be able to accurately represent what do I have, make sure that I know where it’s located so I can get it to my customers quickly.”

— Troy Graham, Descartes

What is the first thing I should fix if I want to scale operations?

Start with a unified view of inventory. The core of maturity starts with being able to accurately represent what you do have and make sure that you know where it’s located to get it to customers quickly. Without a unified view across your warehouses, 3PLs, and vendors, you cannot make the best decisions because you don’t have the best information at hand.

With Inventory Visibility, Businesses Can Make Smarter Allocation Decisions

Once inventory is centralized, businesses can move from reactive updates to intentional allocation. They can decide how much inventory to expose to each channel, when to use buffers, which marketplaces need extra protection, and how seasonality or campaign performance influence availability.

Once I know what inventory I have, how should I decide where to make it available?

Inventory allocation should reflect where orders are coming from, where marketing is working, and which channels carry the most risk. Once you know what you have and where it is located, you can think more strategically using centralized inventory to make prioritization happen automatically. One fertilizer company lost a little over 5,000 orders in one weekend because someone manually uploaded the wrong available inventory to Amazon.

Better Inventory Data Improves Planning, Purchasing, and Growth Bets

Better visibility turns inventory data into a planning tool. With insight into sales velocity, inventory levels, vendors, and channel performance, businesses can make more informed replenishment decisions, avoid overbuying, and test new product lines or vendor-supplied inventory without taking on unnecessary risk.

“You have to have unified inventory to know how to price your products just at that basic level. I can’t price my products if I don’t know the true cost to get it.”

— Mike Bernico, Flxpoint

How does better inventory data help me make smarter buying decisions?

It lets you measure whether your plan is working before you commit more capital. A key question becomes: “Did my plan work? Am I overleveraged in one place or another?” Centralized systems can also help businesses test new product lines or vendor relationships by looking at sales velocity by channel, allowing them to take risks in a calculated and measured way.

Intelligent Order Routing Turns Inventory Complexity Into Automation

Once inventory and supplier data are reliable, businesses can automate fulfillment decisions. Orders can be routed based on cost, speed, margin, location, warehouse priority, vendor fallback, split-shipment rules, or customer expectations. This helps hybrid fulfillment scale because every order does not need a manual review.

How do I decide the best way to fulfill each order?

There is no single answer, which is why order routing needs to account for the context of each order. Intelligent order routing is not just sending an order to someone who has stock; it is taking each and every order and treating it like its own unique use case. Depending on the order, the business may prioritize speed, margin, an internal warehouse, vendor fallback, or preventing split shipments.

Supplier Inventory Sync Extends Inventory Beyond the Four Walls

For hybrid fulfillment to work, supplier inventory needs to become part of the operating model. Supplier sync does not always require advanced technology; it can happen through automated files, FTP, email, APIs, EDI, or ecommerce storefront integrations. The key is replacing manual updates with automated, reliable supplier data.

Can supplier inventory really be treated like part of my own inventory?

Yes, but the goal is not necessarily to force every supplier into a complex integration. Real-time supplier sync can be defined as any way to get an automated update from a supplier, such as Google Sheets, email, FTP, API, EDI, or ecommerce storefront connections. The key is that accurate supplier stock is foundational. If you don’t have an accurate view of what is in stock with your suppliers, you cannot tell your sales channel accurately what’s available.

Exception-Based Workflows Keep Humans Focused Where They Matter

Automation does not remove people from the process. Mature operations let technology handle the routine majority while humans focus on exceptions, such as high-value orders, fraud risk, compliance requirements, restricted products, export rules, or unusual fulfillment scenarios.

If my business has special cases, can automation still work?

Yes. The point is not to automate every possible decision; it is to automate the routine work and surface the exceptions. Businesses should not have to look at every single order. Instead, technology can highlight high-value orders, risky locations, or compliance requirements. The goal is to take care of the 80% of workflows that are obvious while still allowing human review when specific exceptions arise.

The Right Inventory Technology Should Fit the Business, Not Overwhelm It

Software decisions should be based on business fit, not popularity, feature volume, or broad “all-in-one” promises. Growing ecommerce businesses should identify their highest-impact bottleneck, prioritize what matters now, and choose technology that is right-sized but flexible enough to support future phases of growth.

How should I choose software without overbuying or picking the wrong system?

Start with your priorities, not the biggest feature list. Avoid an all-in-one system that claims to “do everything under the sun” and look for a “best of breed approach” with systems that can scale as you add channels or vendors. The practical advice is to stack rank what matters now, make sure the system can support future phases, and choose technology that fits your business rather than overwhelming it.

Ecommerce Fulfillment Operations FAQ

What Is Ecommerce Fulfillment Operations?

Ecommerce fulfillment operations are the processes that move an online order from purchase to delivery. This includes managing inventory, syncing product availability across channels, routing orders to the right warehouse, 3PL, supplier, or vendor, and making sure the customer receives the right product on time. As discussed in the webinar, fulfillment is no longer limited to “what’s in my warehouse these days”; growing businesses may rely on internal warehouses, 3PLs, marketplace fulfillment services, and supplier inventory at the same time.

What Are Ecommerce Fulfillment Operation Examples?

Examples of ecommerce fulfillment operations include updating inventory across Shopify, Amazon, Walmart, and other sales channels; allocating inventory to specific marketplaces; sending orders to an internal warehouse, 3PL, or vendor; syncing supplier inventory through files, APIs, EDI, email, or FTP; replenishing warehouse stock based on sales velocity; and flagging exceptions such as high-value orders, compliance requirements, or restricted products. In the webinar, the speakers also discussed hybrid fulfillment examples where a business may fulfill some products from its own warehouse and use vendors as a fallback or extension of available inventory.

How Can I Track My Inventory at an Ecommerce Fulfillment Center?

The best way to track inventory at an ecommerce fulfillment center is to create a unified inventory view that shows what is available, where it is located, and how that inventory connects to each sales channel. That means tracking inventory across internal warehouses, fulfillment centers, 3PLs, marketplace fulfillment programs, and supplier locations instead of relying on disconnected spreadsheets. The webinar emphasized that businesses need to “accurately represent” what they have and know where it is located so they can get products to customers quickly.

How Can I Connect My Inventory to My Supplier?

You can connect supplier inventory through several methods, depending on what the supplier supports. The webinar discussed low-tech and advanced options, including automated Excel or CSV files, Google Sheets, email updates, FTP servers, APIs, EDI, and direct connections to ecommerce storefronts such as Shopify, BigCommerce, or Magento. The key is to ask suppliers how they share inventory today, then use a system that can automate that data flow instead of manually copying supplier inventory into spreadsheets.

What Is Ecommerce Order Routing?

Ecommerce order routing is the process of deciding where an order is fulfilled from after a customer buys. In a simple operation, every order may go to one warehouse. In a more complex or hybrid fulfillment model, the best fulfillment source may depend on inventory availability, shipping speed, cost, margin, customer location, warehouse priority, vendor fallback rules, or whether the order should be split. The webinar described intelligent order routing as treating each order like its own use case, so businesses can automate the best fulfillment decision without manually reviewing every order.
