Frequently Asked Questions

Find answers to common questions about QR codes

What is a QR code?
Quick Response codes, or QR codes, are a kind of matrix barcode that may hold text, URLs, and other data. It enables instant access to the encoded data when scanned using a smartphone camera or QR code reader.
What is error correction in QR codes?
A QR code with error correction can still be read even if part of it is broken or obscured. While higher error correction levels boost the QR code's resilience, they also make it larger and more complicated.
How do I scan a QR code?
The majority of contemporary smartphones have a camera app that allows them to scan QR codes directly. Just launch your camera, aim it at the QR code, and press the alert that shows up. You might need to download a specific program for scanning QR codes if your smartphone is older.
Is there a limit to how much data a QR code can store?
Yes, there are data capacity constraints on QR codes. The maximum is determined by the type of data and the degree of error correction. Up to 4,000 alphanumeric characters or 7,000 numeric digits can typically be stored in a QR code.
