How to accept online payments (FZ-54)?

Question

Electronic accounting

Hello,
I decided to switch to online payment.
Now the fiscal registrar (atol 22ptk) is connected to the cash register at iiko, an agreement has been concluded with OFD. There is an Internet acquiring agreement with the bank.
What is left to do to accept online payments and send checks by email?
Do I understand correctly that I will have to separately connect an online cash register like Atol-Online, or are there other options?
PS Maybe there are specialized forums for such questions?

Answer 1

if there are few orders, you can manually punch a check
even at Atoll push-button cash desks, you can enter a phone / email when punching a check and using OFD the check will be sent, they take money for SMS

Answer 2

This you need to ask your acquiring.
The payment is not made by you, but by them.
It is possible that they already have a suitable ready-made service.
