2.3.6.4.1. Introduction to Contactless

"Contactless" is the term that was invented and widely adopted by the Smartcard industry
to characterize a new way to read smartcards. By using radio signal, it is possible to read
cards at a short distance, without inserting a card in the reader, thus the name
"contactless".
Contactless technology is sometimes mixed with Radio Frequency Identification (RFID),
which is partly true since both use the same principles: a reader (sometimes called a
coupler) sends a radio frequency (RF) wave through a card or a tag containing a coil and a
small chip RF power energizes the coil, giving enough current to power the chip and allows
data transmission both way.
It should be noted however that RFID is mostly used for identification of objects and
animals, and is based on a wide range of frequencies (from 125 kHz to 5 GHz). On the
contrary, contactless allows the use of microprocessor smartcards with more security and is
preferred for the identification of persons (for ID, payment and others uses). Contactless
uses only one frequency: 13.56 MHz.
