I have online payment terminal. For customer to use it he have to open a link in browser on a phone to continue through payment forms. Firstly a have to give him (a customer) the link with terminal by sending him a message.
I need to give a customer an easiest way possible to pay through online terminal without messing around with sending messages
I developed a method by giving them QR code with the link but due to lack of tech culture many customers don't know how to use it.
Additions: Customers have to enter card data (card number, cvv, expiration data) manualy in forms provided by url link everytime they make payments.
