Acceptance of payment cards on the site, PCI DSS or not?

Question

Payment systems

Do I need to have a PCI DSS security certificate to enter payment card data on the site and transfer it to some aggregator?
I’m thinking, it’s unlikely that any of the payment aggregators work differently?
Still, this is a direct transmission of very important information, and in any case, no one will work differently.

Answer 1

Why do you need data entry on your side? can you explain your scenario requiring this functionality? The last time I studied the documentation for entering payment data on my side, the service provider undertook to conduct acceptance tests for this functionality. Requirements? lack of client logic (only input validation), https protocol.
If you need a custom design for your data entry page, please get in touch with your service provider. Many will go to the meeting under certain conditions.
Only now, considering the cost of certification and audit according to PCI DSS, I wonder why you are asking such questions here. You should have a whole department of technical specialists on this subject.
