Sony develops biodegradable smart card
September 9, 2004
TOKYO - Officials at Sony Corp. said the company has created a contactless smart card made from biodegradable plastic or a plant derived material.
The smart card is made from polyactic acid mixed with special additives. But despite itÃ¢â‚¬â„¢s make-up, chips embedded between sheets of the plastic can still transmit signals. The smart cards are also as strong as their oil-based plastic counterparts.
Sony Corp. and Mitsubishi Plastics worked together to develop the material for the smart card. ItÃ¢â‚¬â„¢s unclear when the product may hit the market, due to the cost to make the biodegradable plastic.
