Tim Horton's became the latest retail chain in recent weeks to implement "contactless" Credit Cards by MasterCard. The debate is ongoing regarding the risks involved however the deployment of these RFID cards and terminals over the last couple years continues. The data on these devices should be largely encrypted and there has not been any report of large-scale fraud using these Cards. The RFID frontier is expanding at a rapid rate to include different forms of government ID (drivers licence, passport, etc.) and PacketMaster will continue to monitor this subject for security issues.
