On many products it is desirable to be able to attach accessories directly to the product housing (i.e. a telephone credit card on a pager so that users have the card readily accessible when they repond to pages, a '(credit card" address/phone book on a cellular telephone so that users may readily access phone number of the persons they wish to call, a "credit card" calculator on a pocket pager so that multiple items do not rattle around in the user's pocket, etc.). Rather than directly adhering the device to a product, it is more desirable if the device may bedetached for independent use. Ratherthan merely providing aslot in the product into which the device is blindly inserted, it is more favorable if the device is visible and functional in its nested position. Finally, a means of securing the device is essential so that it does not dislodge from the product if held in any position.
