Payment Process
Using a successful credit card payment as an example, the payment process consists of the following sequence of events:
- The customer selects to pay by credit card and sends his card data via SSL encryption to the merchant's web shop.
- The Web shop sends the payment data to the POSH service, SSL encrypted.
- The POSH service sends an authorization request to the acquirer's system and expects an authorization response.
- The POSH service sends the transaction result to the Web shop.
- The Web shop displays a payment acknowledgement or a denial to the customer.
