Imagine not that long ago driver’s license had no photo on it and company employees were using paper punch time cards. Words like electronic chip or biometrics sounded more like space science than something that fits your wallet. New security needs as well as technology advance resulted in a revolution of public, private and corporate identification. ID card incorporated widely used plastic credit card format. PVC material gave the card durability while magnetic strip allowed for data encoding. Soon enough plastic card industry found out the differences in needs between corporate ID card and credit card. When compared to worldwide retail sales industry using credit cards corporate environment allows for quicker accommodation of new technology. First improvement in ID card data encoding came again from retail sales industry. A bar code, similar to the one that every product in the supermarket carries was put on the card. This new feature allowed for non-contact, optical, card data information reading; not only faster process but also less stress put on the card. Bar codes are still widely used in Government identification like driver’s licenses and state ID cards. Using bar code scanner is a simple process for experienced operator but ordinary user might experience difficulties scanning a barcode. Despite the advance in optical scanning technologies bar code put against the scanner does not always read. You can see this a lot in self checkout lanes at your local supermarket. It became clear that corporate environment needed another solution.
