In some embodiments a secure card is disclosed with a body; and, a plurality of contacts. The contact may be in communication with storage media in the body of the card. The storage media may store identification information for the secure card. The plurality of contacts are optionally disposed proximate to an edge of the body. Optionally the contacts are rounded and/or spaced apart from each other to avoid short circuits when the secure card is placed in a connector. Some embodiments include a connector having interface elements corresponding to each of the card contacts. For example, the connector may connect between the contacts and a computer port. Optionally the card includes an integrated circuit in communication with said storage media and configured for communication in accordance with a standard computer port communication protocol with each of contacts corresponding to a contact of the protocol.

Various embodiments provide a dual purpose press-bar and heat sink for an integrated circuit card (ICC) reader. The dual purpose press-bar and heat sink provides two functions. First, the dual purpose press-bar and heat sink conducts and dissipates internal heat generated by a high data transfer ICC inserted in to the ICC reader. Second, the dual purpose press-bar and heat sink ensures that contact pads of the high data transfer ICC create reliable electrical connections with ICC contacts of the ICC reader. As such, the dual purpose press-bar and heat sink simultaneously dissipates heat from a high data transfer ICC and ensures that a high data transfer ICC maintains proper electrical connections with ICC contacts of an ICC reader.
