A Bitcoin QR code lets someone pay you by scanning instead of copying and pasting a 26-to-35-character address. It's faster, and it removes the risk of a copy-paste error sending funds to the wrong place.
Basic vs Payment-Request Codes
A simple QR code just encodes your wallet address. Some generators also support a "payment request" format that can include a specific amount, so the sender's wallet pre-fills both the address and the amount — useful for invoicing an exact sum rather than leaving it to the payer to enter manually.
Steps to Generate One
- Copy your Bitcoin address directly from your wallet.
- Paste it into a free Bitcoin QR generator (add an amount if the tool supports it and you're invoicing a fixed sum).
- Generate and download the code.
- Scan it with your own wallet app before sharing it to confirm the address is correct.
Where to Use It
- On an invoice for a client paying in BTC
- At a physical point of sale, printed and displayed
- In an email or messaging app when a text address would be error-prone
