Glossary: Contactless Chip Card

Card which does not need to make physical contact with the read-writer in order to work because it passes electrical or magnetic signals through the air. Some operate only a few millimetres away from the reader; others work at many metres. The remote linking is either by capacitative or inductive coupling. More expensive but more reliable and sometimes more tamper-proof than contacted cards. The remote link is by either capacitative or inductive coupling.
