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.
