Hello everyone, who can explain to me what a cash register program is and what its functions are, is it possible to integrate such a program into an online store?

Good afternoon, when starting an e-commerce site, be sure to take care of the payment system. This is one of the most important components when creating a website. The security of online payments should be in the first place, for this you need software for cashier. If you get your payment processing right, your customers will trust you and recommend you.
