Printing a QR Code on ID Badges, as well as VIP, gift, loyalty and discount cards is gaining popularity. Here’s everything you need to know about why that’s the case, which QR code is right for you, and where to go for all your QR code printing needs.
How does a QR Code Work?
Anyone can use printed cards for tracking or validation purposes in attendance, access control, transportation, or similar applications. Each card needs a unique ID number. Typically that ID needs to be read by an electronic device. The device will record it or validate it against a database.
What are the Details?
Typical readers for these applications include barcode, magstripe and RFID/NFC readers. The use of magstripes and 1D barcodes are most common. However, RFID/NFC and QR codes are increasing in popularity. RFID/NFC technology is often used when security is a high priority. This is because the embedded RFID/NFC chip is difficult to fake if properly implemented. The tradeoff is cost. Cards with these chips are significantly more expensive.
Why are QR codes gaining popularity?
QR codes have been gaining popularity because apps can scan them far easier than 1D barcodes. QR codes require the built-in cameras of smartphones and tablets. The fastest scanning in most ambient conditions and even off-axis is done using the device’s rear-facing camera. They can also be scanned with front-facing cameras. This is ideal for unattended scanning (‘kiosk mode’).
Where can I go to get some printed?
Many printers can print QR codes. But you need to specify ‘variable’ QR codes. In this case, each card has its own unique ID embedded in the QR code. That ID is associated to the card-holder in a database for tracing and validation purposes.
