QR Code
wallet
ux
A machine-readable square barcode commonly used to share wallet addresses and payment requests.
1
basic
Wallets use QR codes to encode addresses, payment URIs, invoices, or other short pieces of transaction data. Scanning avoids manual typing, reduces copy-paste mistakes, and is especially useful for point-of-sale payments.
2
safety
A QR code is only an encoding format, not a trust signal. Users should still verify the amount, asset, and recipient details shown by their wallet before sending, especially when scanning codes from websites, emails, or stickers in public places.
