Good question. The profile page is used for payments of all types. Technically,  we are not a "POS".

With merchants that use us, they have 2 options.
1 - Have a tablet/smartphone with Coinos on it for the cashier to open for the customers to scan, or add a Coinos button to the current tablet being used.

2 - Have a QR code printed & a small 4inchx3inch printer for the cashier to have on-hand. Cashier tells the customer what they owe, customer scans the QR code, sends the payment, then the printer prints a receipt confirming the payment.
This is less work/steps for the cashier than Visa/MasterCard.
