Open the CIPO recordAbstract From the Canadian patent
A credit card system (100) is provided which has the added feature of providing additional limited-use credit card numbers (126) and/or cards. These numbers and/or cards can be used for a single transaction thereby reducing the potential for fraudulent reuse of these numbers and/or cards. The credit card system finds application to "card remote" transactions such as by phone or Internet (112). Additionally when a single use credit card is used for "card present" transactions so called "skimming" fraud is eliminated. Various other features enhance the credit card system which will allow secure trade with the use of elaborate encryption techniques.

Why it's free to use
- Filed March 25, 1999 and granted December 30, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 25, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 25, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
