On the encrypted connection between the payment terminal and the network operator / bank, in addition to the payments made using the technical standards BMP43 or BMP60, other data can also be transmitted on request. This can be, for example, customer information or links that are passed on to the buyer's account statement or telemetry / accounting data, e.g. which product was purchased. This not only supports telemetry applications, but also enables precise VAT accounting, for example in vending.

There are many millions of machines on the market that either do not have a connection for a cashless payment system or only support a mechanical coin validator that emits an electrical boost after a coin has been thrown out. For these applications, FEIG Payment Terminals have an integrated fixed price system with a relay output. A fixed price and the switching duration of the relay are set in the payment terminal. In this mode, the terminal is always ready to pay and after holding the card and successful authorization, the relay closes for the set time. Alternatively, the Impluse can be emulated with common coin validators. Thanks to this innovative function, all key-based machines can be equipped with a modern payment system in a simple, uncomplicated and on-site manner.
