Abstract
A contactless transaction card includes first and second contactless integrated circuit (IC) chips and an antenna connected to both ICs for enabling contactless operation of the functions provided by each IC. The contactless transaction card is preferably fabricated by laminating together a plurality of layers to form a carrier substrate. The antenna and one of the IC chips is embedded within the layers of the carrier substrate so as to be permanently formed in the card, while the second IC chip is provided in the card in a region formed as a micro-sized card which is removable from the main portion of the carrier substrate. Additionally, an adapter card includes a holder for retaining a micro-sized contactless transaction card and contains an antenna arranged to connect with the micro-sized card. The adapter may be used to convert the micro-sized transaction card into a full-sized card and to enable access to the information associated with the IC chip contained in the card.
