Abstract
Embodiments of the invention are directed to access transactions. A gate access device may interact with a payment card such as a credit card. The gate access device may generate and transmit a first authorization request message to a payment processing network computer. The first authorization request message does not include an amount for the transaction, but only contains identification information. A first authorization response message is transmitted back to the gate access device. At a later point in time, a second authorization request message containing the transaction amount is transmitted from the gate access device to the issuer, and a response is received from the issuer.
