Abstract :
Contactless smartcards are widely use in transport systems, banking systems, identify cards etc. More and more data and operations are being stored and performed in the contactless smartcards, but the power acquired from the reader is limited. To allow more operations to be performed in the cards, the asynchronous circuit technique that promises lower power is an attractive solution. This paper describes an approach in this direction.
