Tech Questions, Straight Answers
QR codes can be damaged up to 30% and still scan. That's the magic of Reed-Solomon codes.
What is error correction?
QR codes can be damaged up to 30% and still scan. That's the magic of Reed-Solomon codes.
How much data can a QR code hold?
Up to 7,000 digits or 4,000 characters of text. Enough for a small novel!
QR vs barcode: what's the difference?
Barcodes hold data in one direction; QR codes hold it in two, making them far more powerful.
