What payment method to choose for the site?

Question

Payment systems

Good day!
The essence of the question is as follows:
I am making a website for foreign countries (EU).
A small shop with 4 products and a rare frequency of orders.
The customer wants a payment system, but without IP registration.
I flatly refused PayPal and other things.
He said that it is desirable, in general, that a person simply receives a check for payment, and after payment, the owner receives a payment report and he sends the goods.
What do you advise? And how to implement?
I will be very grateful for a detailed answer.
There is one idea, but I'm not sure about the implementation either.
If anyone remembers the old sites, or some "frivolous", then there was such a system:
choose a payment method (webmoney, qiwi or something else), choose a product. A code is generated for you, which you need to write in the comment for the payment, and the number or account you need to pay for is shown. Then you just go to Qiwi, for example, and enter the payment number and code in the payment comment, and then you receive a letter that you paid for the goods.
I really need help!

Answer 1

With such volumes, what's the point of bothering? Just when ordering, display all the electronic wallets that you have and it will work like a donation, only in the comments let them indicate the order number, which you will display in large red letters when confirming the payment. To check at least in manual mode, even with simple scripts, I think right now all electronic wallets have api for the history of receipt of funds. And so the easiest way is to register on the rapid-type aggregates, or to conclude an acquiring agreement with the bank and receive it already on the current account.

Answer 2

customer / seller from which country?
