摘要
A system and method for connecting and operating two (2) or more secure keypad devices under the domain of a single processing board is disclosed. The processing board communicates with a security module responsible for host transaction processing. The processing board lies between the keypad and the security module serving both the security module (downstream) and the keypad(s) (upstream). The system permits multiple secure keypads to be used in a manner that is invisible to the security module. A unique message sequence is disclosed among multiple keypads in which only one keypad may be deemed active at a given moment for purposes of passing transaction data through the processing board to the security module. The processing board is responsible for linking each of the keypads together and funneling message traffic among them. A system is disclosed for secure PIN transactions occurring at a single pay point between a plurality of secure keypad devices and a security module configured to communicate with a single secure keypad device. The system may not include an intercessor device between the secure keypad devices and the security module.
