Abstract
Abstract The invention relates to exchangeable memory cards having several integrated circuits for personal computers. These memory cards serve as a large capacity mass memory for replacing floppy disks and other exchangeable magnetic supports. In particular, they have a plug-in connector (12) at the end of the card and can be inserted in the reader in accordance with PCMCIA standards of a microcomputer. According to an aspect of the invention, a flush contact chip card memory is formed by such a plug-in card (10) and for this purpose the latter has a supplementary connector with flush contacts on its principal face (14). The thus formed reader is transportable, with its application software stored in the card (10) and can be installed in any random microcomputer equipped with a PCMCIA reader. A credit card or security card (18) can then be inserted in the transportable reader. The memory card is typical a PCMCIA size card with a recess on one major plane surface and the security cards fits into this recess.
