Contactless small card operates without any physical link with the reader: communication is performed through microwave frequencies. It consists of a chip, an antenna and a paper support/media or a laminated plastic card. The chip is the core enabler of contactless plastic cards: it controls all communication with the reader, as well as data storage, data encryption and security of access. The card will operate when brought to within 3 to 10 cms of the reader. Some contactless cards use radio frequencies and will even operate from a longer distance.
Tungsten contactless smart card can be used for many popular applications including, but not limited to, public transport for fare payments, access control, cashless vending, parking, loyalty, e-purse, gambling and ID Cards. Recent advances in silicon technology enable the contactless interface to provide sufficient power for more secure microprocessor cards and larger memory sizes.
