<p>A system for use with smartcard type devices 11, 21 including a remote station 13, 23 used to interface with a smartcard type device 11, 21 to send location, time stamp information and prior usage information for the smartcard device to a central server 17, 27. The central server 17, 27 can be a tracking station or a centralized station to keeping records related to use and location of the smartcard type device 11, 21. The interface between the smartcard type device 11, 21 and the docking station can be used to make a payment, provide a map with directions, or provide information related to previous uses of the smartcard type device 11, 21. Information relative to previous locations and transactions for the smartcard type device 11, 21 can be downloaded to the smartcard, including maps and itemized lists. The smartcard type device 11, 21 allows the user to easily retrace routes and transactions from previous uses for which the smartcard type device 11, 21 was detected. The system can also allow explicit requests for former locations of the smartcard type device 11, 21 and a central server 17, 27 can return map data on how to get that particular position from the current location. The directions to the last known location may, for example, be directions to the location of the user's car in a parking garage or to a shop previously visited by the user.</p> |
