Embodiment Construction

[0060] A description of structural embodiments and methods of the present invention will be provided with reference to FIGS. To practice the invention, like elements in different embodiments are generally shown with like reference numerals.

[0061] 1A and FIG. 1B illustrate various components in a dual-interface SIM card carrier 10 comprising a chip card 20 of a first size from a bottom perspective view (or bottom view) and from a top perspective view (or top view), respectively. explained. The dual interface SIM card carrier 10 comprises a circuit board 30, such as a flexible printed circuit board, a housing or chip housing 40 to cover the smart card 10, and a cap 50 adapted to the housing 40 to hold the smart card 20 in a stable position. A typical example of a chip card 20 of the first size is a miniature dual interface subscriber identity module card, or subscriber identity card.

Abstract

A dual interface SIM card adaptor is described for use with an existing SIM card slot that provides a dual interface electronic information storage card. The dual interface SIM card carrier comprises a flexible printed circuit board, a mini-sized SIM card, a housing to house the mini-sized SIM card, and a cap to affix the mini-sized SIM card in place. The mini-sized SIM card has dimensions that are less than the dimensions for a typical SIM card. The mini-sized SIM card is separable from a carrier that holds the mini-sized SIM card and an antenna. The adaptor is inserted into the SIM card slot in a mobile handset for contact electronic communication, such as wireless telecom, and for contactless electronic communication, such as public transportation, payment and RFID. Contactless communication can be carried out by RFID, Near Field Communication or bar codes.

Description

technical field [0001] This invention relates generally to electronic circuit cards, and more particularly to an adapter for dual interface electronic information storage cards for contact and contactless communications. Background technique [0002] The use of electronic information storage cards, such as smart cards, has grown rapidly over the years as mobile devices have rapidly replaced cumbersome and large and difficult-to-carry notebook computers among people in both industrial and developing countries. This trend is especially evident in developing countries like China and India, where new infrastructures are based on the latest wireless network technologies rather than landline systems. In these developing countries, as the economic growth in these countries has surpassed that of industrial countries, the use of mobile phones has thus made great progress. [0003] Smart cards can be used in a wide range of applications including mobile phones, credit or automated te...
