Proximity cards, also known as prox cards, are low frequency 125 kHz credentials that feature an embedded metallic antenna coil that stores cardholder data. Data stored on a proximity card, key fob or tag can be detected by a reader when the proximity card is passed within range.
The technology of proximity cards and keys in corporate buildings, hospitals, refineries and chemical plants, airports, research laboratories, schools, and other various institutions has proven to be a valuable security measure. It's become easier to control access and manage security in different areas of a facility, as well as, employee badges and photo ID capabilities.
The card and the reader unit communicate with each other through 125 kHz radio frequency fields, (13.56 MHz for the contactless smartcard cards) by a process called resonant energy transfer. Passive cards have three components, sealed inside the plastic: an antenna consisting of a coil of wire, a capacitor, and an integrated circuit (IC), which contains the user's ID number in specific formats and no other data. The reader has its own antenna, which continuously transmits a short range radio frequency field.
