The SAP POS application currently supports electronic signature capture devices as well as personal identification number (PIN) entry devices for payment card transactions. Electronic funds transfer (EFT) user exit architecture is also available, which uses different dynamic link libraries (DLLs) for different devices for communication to the financial host. With EFT user exits, the EFT device receives the card information and communicates this information to the financial host. Each new device has a new DLL.

With this release, the existing EFT user exit is extended to use the POS card reader, to use CEFT (Centralized Electronic Funds Transfer) as a communication infrastructure to the financial host, and to implement a sample DLL for signature capture. The following new functions are available:

  • Signature Capture

    Allows the EFT user exit to capture a signature image from a signature capture device, print it on the receipt, and save it in the journal.

  • Manual Card Entry Callback

    Allows a cashier to manually enter a card number at the POS when the magnetic strip reader (MSR) of an EFT device is defective or is unable to read the card.

  • Card Input at the POS

    Allows a cashier to capture card data using a POS peripheral, when the MSR of an EFT device is defective or if it is missing from the device.

  • Indirect CEFT Request Callback

    Provides the ability to capture a card at the pinpad/signature capture device, or any other credit reader, and use the existing CEFT logic to process the credit/ debit request. The existing POS/CEFT logic is used for the processing of requests and responses, including offline situations. This would be useful, for example, in a situation where credit/debit cards are authorized by the PED/signature capture device.

  • Direct CEFT Request Callback

    Provides the ability to send requests and process responses to and from CEFT directly from the DLL. The customer is also free to implement their own offline functionality.

  • New PIN Entry Device (PED) User Exit

    There is a new user exit for PEDs and signature capture devices. This PED DLL includes standard PIN pad/sigcap functions, such as receive card data, receive signature, and display text. These functions can be called either from the EFT user exit, or directly from the POS.

  • New PED Support

    Verifone MX 870 is a sample implementation PED. In the EFT user exit, you can use this PED DLL as a functional sample code to develop PED DLLs for other devices and manufacturers.
