The microchip communicates through radio frequencies with the receiver inside your vehicle. These signals are a form of near-field communications (NFC) which allows for contactless payment and other features that require proximity.

This can be very beneficial in preventing crimes. Security measures can also be added by using encrypted keys, which make it more difficult to copy. Prox cards are an extremely popular fob type and are sometimes called 125khz cards, 26-bit proxy, or proximity fobs.
