An easy prepayment option for a mini-hotel?

Question

Machine translation from one language to another

Good afternoon!
I'm a little behind the times, so I want to know the opinion of experts.
The essence is very simple: there is a mini-hotel that needs to receive an advance payment from people who book accommodation by phone. Now there is a banal transfer to a bank account, but almost no one uses it.
I would like to install some simple "prepayment" button, by clicking on which a person would be able to make, in any way convenient for him, a transfer.
Are there such solutions? (If anything, then the company is official, IP, so concluding an agreement is not a problem).
