Prepaid Products

The term prepaid products refers, for example, to cell phone credits.

During sale, the prepaid products are transferred to the receipt. The credit itself is supplied by an external provider. The top-up process starts directly after the tenders have been entered. Upon completion of the payment process, the customer receives an additional receipt. This receipt contains the PIN, which is generated by an external provider. This PIN allows the customer to top up the cell phone credit.

If an error occurs during the top-up process, no correction will be made on the current receipt. If an error occurs for one or several prepaid line items, a return receipt will be automatically generated after the transaction, indicating the erroneous prepaid line items. Possible causes of the error:

• It is impossible to connect to the terminal/web service. The corresponding timeout was exceeded.
• An error occurs during communication with the prepaid provider. The provider is not accessible.
• Other errors (unknown product, invalid amount, etc.)
• No error is reported. However, no print data is available.
