Abstract: An intelligent credit card payment system and payment processing method may be implemented to perform duplex payment through VAN or PG linking so that payment can be stably performed, in consideration of the problem that credit card payment is no longer available due to reaching the monthly limit set by a card company for a member store, or for another reason due to the member store. To this end, an intelligent terminal, a VAN network, and a PG network are included, so that: according to a configuration for an intelligent terminal, VAN approval information is converted into PG approval information, and thus payment processing according to VAN linking is changed to payment processing according to PG linking; or PG approval information is converted into VAN approval information, and thus payment processing according to PG linking is changed to payment processing according to VAN linking.

Abstract: A system and method is described for the touchless entry of a personal identification number (PIN) at a self-service terminal such as an automated teller machine (ATM). A mobile device includes a PIN entry application. The self-service terminal includes a wireless interface for communicating wirelessly with the PIN entry application in the mobile device. A communication channel is established between a particular customer's mobile device and the self-service terminal.
