Who this is for
Coffee carts, market vendors, freelancers who invoice, salons with personal pay-links per stylist, food trucks, mobile detailers, and any small business that already uses a Square / Stripe / PayPal / Venmo / bank pay link. We don't connect to those services—you paste the public URL.

When to use it
Best at the moment of payment: counter sign next to the card reader, tip jar, market booth, or printed on an invoice. Customers scan, your processor handles the transaction the same way it always does.

Print & display tips
For tip jars, a small 3 cm card sitting against the jar works well—keep the wording soft ("scan to tip"). For checkout, a 4 cm sign next to the reader is enough. Run a small real test (a $1 tip or sandbox checkout) before printing big batches to confirm the URL behaves correctly on a phone.
⚠️
Common mistakes to avoid
Don't use a per-invoice URL that expires. Don't put the QR somewhere customers can be photographed entering payment details over their shoulder. Regenerate immediately if your pay link rotates, and verify the destination page shows the correct business name before printing.
