Abstract
A method of remotely synchronizing pin-pad terminals involves a gateway receiving from an acquirer server an authorization code for a transaction authorized using one of a plurality of pin-pad terminals, and saving in a database particulars of the authorized transaction. Each terminal has a memory storing particulars of at least one authorized transaction authorized using the terminal, and a running total value of all transactions authorized using the pin-pad terminal. The gateway receives a request to close out all the saved transactions and receives from one of the terminals an authorization request message requesting authorization for an additional transaction. In response, the gateway closes in the database all the saved transactions authorized using the one terminal, and responds to the authorization request message by providing the one terminal with a remote synchronization command commanding the one terminal to clear the running total from the memory.
