ABSTRACT:
A multiple application card data system comprises a data management device and a user card. The user card includes a first memory for storing provider data, and a second memory, separated from the first memory, for storing data unique to a user. The data management device compares a unique set of user data on the device with the data on the second memory of the user card for identification of the proper user card. The device also includes a stored digital representation of the user's fingerprint and a fingerprint scanner for imaging of a fingerprint for comparison with the digital representation of the user's fingerprint for identification of the proper user. A memory in the device stores copies of data from a plurality of provider data cards. The device enables transfer and storage of the data of one provider on the first memory of the user card, making the user card an effective clone of that provider's data card. The provider data on the first memory can be re-encoded as desired. The user card also includes an electromagnet for time delayed erasure of data stored on the first memory. The data management device includes a card reader capable of simultaneously reading a data card having two magnetic strips.
