Contactless technology is based on an RF (Radio Frequency) communication process. The contactless smart item does not have a battery and instead is powered by the RF wave emitted by the reader. The embedded antenna works as an RF power collector. The chip is connected to this antenna to receive power and to communicate with the reader.
Thanks to a large scope of communication protocols and ranges, whether proximity, vicinity (High Frequency) or long-range (Ultra High Frequency), all kinds of transactions may be performed via a contactless interface for people or object identification.
Communication range depends on the ISO protocol and the chip but it may also vary according to the size of the reader, the card antenna and the environment.
Contactless technology is a must when high throughput, high validation speed and secure systems are required. It can be used for financial applications, secure access control, secure ID credentials and documents, AFC systems and all RFID applications for supply chain, inventory and item tracking.
Today contactless technology is part of citizens' daily life.
Depending on the part of the world:
- You can take public transport with a contactless smart card, paper ticket, smart object
- Pay with your contactless NFC phone or contactless banking card
- Access facilities with your contactless badge
- Travel worldwide with your ePassport
- Cross the borders with your Enhanced Driver Licence
and use contactless for many other applications...
