Whether you own a small business or are at the helm of a conglomerate, tracking inventory should rank high in your priority list. Asset tracking provides visibility into asset usage and other patterns, helping asset managers plan for the future while keeping an eye on the present. Earlier, barcodes were used extensively by businesses for asset tracking. With time, however, thanks to improvement in mobile technology, QR codes are fast becoming the preferred choice of businesses for asset tracking.
Understanding QR codes
Also known as matrix barcodes and 2D barcodes, QR codes or Quick Response codes were first used in Japan in the automotive industry. QR codes, just like barcodes, contain information related to the item they are used for. That said, QR codes have a superior storage capacity than UPC barcodes. An average QR code can store up to 406 bytes of data, which is enough to redirect you to a website or a music video (and open it). Thanks to their design, QR codes are easily scannable and readable.
How to scan a QR code
Scanning a QR code is as easy as 1,2,3. Thanks to the improvement in the quality of smartphone cameras, most mobile devices can scan QR codes. To scan a QR code, all you need to do is follow the below easy steps:
- Download a QR code reader app from Play store or the App Store (for Apple users).
- After downloading the app, open it, and position the camera in such a way that the QR code fits in the frame.
- The scanner will take a few seconds to read the code. Once the scanner successfully reads the code, a popup containing the URL will appear on the screen.
- Tap on OK to visit the website.
Generating a QR code
Generating a QR code is just as easy as scanning one. After you have decided the type of information you want to encode, visit a QR code generator website. Once you are on a QR Code generator website, you can select and generate the type of QR code that best meets your requirements.
Different types of QR codes
Depending on the purpose that they are expected to serve, QR codes can be classified into the following types:
These are the most popular type of QR codes. These QR codes are created to direct the user to a website. Once on the website, the user will be exposed to the content uploaded to the site.
These QR codes contain contact information such as your name, company details, address, and email. Once scanned, these details are automatically stored on the phone. They are also known as virtual business cards.
These QR codes contain credentials related to a wireless network. Once the user scans the code, their smartphone is automatically connected to the network.
An email QR code contains an email with a recipient, a message, and a subject. Once the user scans the QR code, these details are automatically saved to their mobile device. To share the email, all the user needs to do is tap the send button.
These QR codes include details related to an event. Once a user scans this QR code, the details are automatically added to their calendar with a reminder.
Simplest of all QR codes, plain text includes an encoded plain text. After the user scans the QR code, a raw text is displayed on their screen. The user can write anything on the plain text.
Users scanning these QR codes receive a text message with a predetermined recipient. Once they scan the QR code, the user can send it to the intended recipient.
When a person scans a phone number QR code, a call is automatically started to the embedded phone number.
Dynamic QR codes
Information contained in dynamic QR codes can be edited. Dynamic QR codes include embedded analytics and password protection, enabling the admins to track the number of times they are scanned.
Tips on implementing QR codes
Be careful with the placement
Make sure your QR code is visible from every angle. To achieve this objective, place your QR codes above the fold. Never place a QR code close to the edges or crease.
Include a quiet zone
A quiet zone is free of all markings. Every QR code must have a quiet zone. The quiet zone of your QR code must be equal to the width of at least two and up to four modules around the sides of the QR code.
When using two colors, make sure to keep a contrast of 55 percent between them. If you want to use any shade of red, opt for a light-colored background. For shades of blue, a dark-colored background should do the trick.
Some mistakes to avoid when using QR codes
- Not providing the target audience any incentive to scan the code.
- Using extremely long URLs.
- Starting to use QR codes without testing them.
- Inappropriate placement: Placing QR codes too high or too low, unknowingly discouraging users from scanning them.
- Considering QR codes as a one-dimensional tool.
- Failing to use a strong call to action.
- Putting QR codes in places such as urinals where they are less likely to be scanned.
