Abstract: In an embodiment, an arrangement for executing electronic card payment transactions includes first card reading means (10) for reading data from a payment card (12) and a first process machine addressing the first card reading means, which process machine is set up, in response to the reading of card data by the first card reading means, to cause the sending of an electronic authorization request to a remote transaction authorization system (14, 16). The arrangement further includes storage means (18) for storing an electronic authorization reply returned by the transaction authorization system in response to the authorization request. Second reading means (20-24) separate from the first reading means serve for the second-time reading of data from the payment card (12), a second process machine addressing the second card reading means being set up, in response to the second-time reading of card data by the second card reading means, to query the authorization reply stored in the storage means.

Abstract: Systems and methods are described to provide an interface between distinct host service providers and one or more remotely programmable point-of-sale devices. A set of transaction data may be received from a point-of-sale device. Different subsets of the set of transaction data may be identified for each of the service providers. Each of the identified subsets may be transmitted to the appropriate service provider in a format readable by that service provider.
