Abstract From the Canadian patent

A system for processing credit card transactions is disclosed. Transaction data to be processed is sent by point of system terminal to a terminal node connected to a sophisticated communications network. The terminal node uses routing data contained in the transaction data to establish a connection to a verification service host. The connection is established while the terminal node concurrently continues to receive and then validate the transaction data. Overall transaction processing time is reduced because the network connection needed for verification of the transaction data is established while rather , than after, transaction data is received and validated.

Why it's free to use

  • Filed June 7, 1996 and granted September 4, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 7, 2016.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 7, 2018.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
