Session Management
Last updated: 04-Dec-2024
A session needs to be established between a POS and the SCA before performing any payment transactions.
Rules
- A session must be open for all payment (FUNCTION_TYPE PAYMENT) and line item (FUNCTION_TYPE LINE_ITEM) transactions. Point persists an open state between POS requests using this session.
- If a session is not open, the device will return with “No session” in the RESPONSE_TEXT element.
- The POS system can use a FINISH (FINISH SESSION) to emulate a POS ‘cancel’ or exit of the session as long as the payment transaction is not ‘in-flight’ to the gateway.
- To cancel the session, the POS system should send the FINISH command on the same socket or TCP session from which the START originated. If a different TCP session or socket is used, the device will respond with the DEVICE IS BUSY (59002) response.
