The common question is how the information of e-store buyers’ plastic cards is stored. This information interests both users and potential buyers.
The Bitrix Site Manager software doesn’t accept, handle, or store any plastic cards data. If you use the Ibill or PayPal systems to accept payments for orders, then these systems will accept and store information. The e-store registers the stages of the order handling only, but doesn't store any plastic cards data.
If you attach a payment system that requires closed keys to be installed on server and the user information to be received directly on the order pages, you must use the SSL protocol encryption to secure the customer’s data while ordering. Also, use encryption to store the user’s data in database or files.
