A payment QR code turns a phone camera into a checkout. Instead of typing a long address or hunting for a card reader, customers scan and pay in two taps. Because the code just encodes a link or address, it works for tips, invoices, donations and in-store checkout alike.
Encode your PayPal.me username with an optional amount and currency. The scanner opens PayPal pre-filled, so friends, clients and supporters can pay without you sharing an email. Use the PayPal content type in QRVolt and add the amount only when it is fixed (a set price, a donation tier).
For Bitcoin, Ethereum, Litecoin, Dogecoin or Dash, encode the wallet address directly. Always double-check the address character-by-character before printing — crypto transfers are irreversible. A branded plate and high error correction keep the long address scannable on stickers, cards and screens.
Place a payment QR at the counter, on the receipt, or on a poster. It is cheaper than a card terminal and works offline on the print side (only the customer needs a connection). Pair it with a short caption like “Scan to pay” so the intent is obvious.
