Abstract
An improved transaction card contains electronic components and a thin, flexible, power assembly such as a rechargeable metal-lithium battery which may be used whether or not the card is coupled to a reader. The power assembly may include a built-in power source such as a thin film solar cell for charging the power storage device from that source, on-card. The invention also relates to a method for selectively powering the plastic card from the various power sources.
