Contact smart cards must be inserted into a smart card reader to establish a direct contact between the reader and a micro module on the smart card surface. This physical contact permits the transmission of data, commands and card status.
Contactless smart cards only require close proximity to a reader (typically within a few inches) to enable the transmission of data, commands and card status, hypothetically taking less time to authenticate vs. contact smart cards. Both reader and card have an internal antenna that securely communicates with the other.
Using advanced data encryption technologies, contact less smart cards are every bit as secure as their contact counterparts.
Contactless technology is ideal for mass transit, large corporations or any other entity tasked with moving thousands of people through their GATE/ DOOR ENTRY control systems each day.
This technology brings keyless convenience to physical access control security systems. Proximity cards or RFID cards use an internal antenna that cardholders wave within a few inches of a reader to be granted or denied access.
These cards integrate photo ID, proximity, magnetic stripe and even smart card technology into a single card, eliminating the need to carry multiple cards for different purposes.
A hybrid smart card has two chips embedded into a card’s surface — one contact and one contactless — each with its own interface. This effectively doubles the functionality and security of every card issued.
Combi smart cards allow a single smart chip to securely interface with both contact and contactless readers. The Smart Card Alliance forecasts that the transportation and banking industries will adopt this technology first.
These cutting-edge cards transform CD-ROM technology into a credit card form, capable of securely storing megabytes of personal information. For example, a patient ID could hold an image, health care history, vaccination record, X-rays and more.
