A98-P™ Centralized Operation

Injection

The Target PIN Pad (TPP) to be injected is attached to the KIU.

The KIU recovers the encrypted key sent to it from the A98-P™ System Unit and injects the recovered key into the TPP.

All operations are automatically logged and recorded on the system unit eliminating most of the record keeping associated with the loading of the keys into the TPPs.

The injected TPPs are placed into inventory until needed.

Field Service Representatives (FSR) deploys TPPs without regard to assigning any specific device to a specific location. 

Deployment

The FSR selects a random device for deployment into any store.

The FSR calls the A98-P™ integrated voice response unit (VRU) system unit to report the Serial Number of the TPP being deployed. The FSR enters the store and lane (optional, only for deployments in a multi-lane environment) and the terminal number (or the terminal ID or the terminal serial number, whichever number the specific environment uses to identify an eft/pos terminal) into which the TPP is being deployed.

The A98-P™ assembles a standard ISO8583 message containing the TPP ID and the cryptogram of the TMK it contains, encrypted by a second KEK shared with the host system.

The A98-P™ System Unit provides for either a LAN or a WAN connection to communicate to the host that receives transactions from the eft/pos devices.

The host system receives the message and places the received key into the record for that device in the host database. The host sends an acknowledgement message back to the A98-P™, and the VRU speaks the acknowledgement to the FSR.

The acknowledgement indicates the key update is complete and requests the FSR to plug in the device. Once connected, the host system sees the device and is now prepared to accept transactions.
