A crypto QR code encodes your wallet address (and optionally an amount) so a payer scans it instead of copying a long string of characters — which removes the biggest risk in crypto payments: a mistyped address. It is ideal for donations, invoices and point-of-sale.
Use a payment URI like bitcoin:ADDRESS (or your coin’s scheme), style the code and download a PNG or SVG. It is a static code that works forever with no account. Always double-check the address before you print.
Tip: Verify the wallet address character-for-character before you print.
Put your address in the payment URI format — for example bitcoin:bc1q… — paste it into the generator, and download the code. A payer scans it and their wallet opens with your address filled in.
Yes — append ?amount= to the URI (e.g. bitcoin:bc1q…?amount=0.01) and the payer’s wallet pre-fills that amount, which is handy for invoices and point-of-sale.
The code only contains a public receiving address, so it is safe to share. The critical step is verifying the address is correct before you print — a wrong address sends funds elsewhere with no recovery.
Yes — CalculatorAI's QR code generator is completely free. Create, customise and download as many static QR codes as you want as PNG or SVG, with no signup, no watermark and no scan limit. Static codes never expire. A free account adds dynamic (editable) codes with scan analytics.
Static QR codes never expire — the data is encoded in the code itself, so they keep working forever with no account and no fees. Dynamic codes, which you can edit after printing and track, stay live as long as your free account is active.
Static QR codes are free forever and never expire. Want to change the destination after printing and see how many people scan — from where and on what device? Create a dynamic QR code and track every scan in the QR Codes dashboard.
