Dual Interface SIM Card Adapter with Detachable Antenna
First Claim
1. A dual interface card carrier, comprising:
- a circuit board having first and second principal surfaces, the first principal surface having a plurality of contacts operating as a first interface for contact communication, the second principal surface having a second plurality of contacts operating as a second interface for contactless communication;
a chip card having an inwardly-facing surface with a plurality of contact pads electrically contacting with the second plurality of contacts in the second principal surfaces; and
a chip housing that houses the chip 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.
