There are an estimated four billion smart cards being shipped, annually worldwide, say Electronic Products & Technology. Printed electronic technology such as the displays and batteries in these smart cards are projected to revolutionize the portable electronic industry in the next few years.

These battery-powered cards utilize color-changing displays and integrated circuits to store account information, authentication codes, and any other data that are used to meet the demand for interactive ID security and authentication. They do so using a thin film battery that is low in voltage and environmentally friendly.

Unlike batteries containing lithium, mercury or other batteries, the thin carbon-zinc batteries on these smart cards are lead-free and contain no toxic substances, meeting full compliance of the European Union’s Restrictions on Hazardous Substances Directive.

These battery-powered cards act as contactless credit and debit cards, retail loyalty cards and secure identification card and badges for access control in buildings or at events.
