Offline credit card process system using php

hi all

what is offline credit card process system ? How to implement this in php ?

Thanks

An offline payment system means that you collect peoples details (name address, card number etc) and process the payments manually, possibly using a payment terminal in your office or shop.

If you are doing this you need to be very careful to ensure the card details are transmitted and stored securely.

It is often better for small to medium sites to use a third party payment processor who take care of the processing and security for you. In the UK SagePay and WorldPay are popular for example.
