REMOTE SYNCHRONIZATION OF PIN-PAD RECORDS WITH A CENTRAL TRANSACTION DATABASE

摘要

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.

主权项

1. A method of remotely synchronizing pin-pad terminals with a central transactions database, each said pin-pad terminal being configured to communicate with a network gateway and having a memory storing particulars of at least one authorized transaction authorized using said pin-pad terminal and a running total value of all transactions authorized using said pin-pad terminal, the network gateway being in communication with at least one of the pin-pad terminals and a merchant acquirer server, the method comprising:
the network gateway receiving from the merchant acquirer server an authorization code for one of the authorized transactions and saving in a central transactions database the particulars of the one authorized transaction; the network gateway receiving a request to close out all the saved transactions and receiving from one of the pin-pad terminals an authorization request message requesting authorization for an additional transaction and, in response the network gateway:
(i) in the central transactions database, closing all the saved transactions authorized using the one pin-pad terminal, and(ii) responding to the authorization request message by providing the one pin-pad terminal with a remote synchronization command commanding the one pin-pad terminal to clear the running total from the memory.
