Abstract: A system to provide a multi-function transaction card is disclosed. In one example, the system includes a card and a functionality transfer unit. The card incorporates a magnetic stripe for transmitting data to and recording data from the functionality transfer unit and for the making of magnetic stripe-based transactions, and contact and contactless provisions for transmitting data to and receiving data from said functionality transfer unit, for the making of contact or contactless transactions and for the card to receive electrical current. The functionality transfer unit is operated to read data from a conventional transaction card, to analyze the data to extract that required to permit said multi-function card to operate as a clone of the conventional transaction card. Commands are inputted via a selection of commands in a display of the functionality transfer unit and executed via pressing of an “Execute” button.
