![]() ![]() Most 26-bit proximity cards use a facility code within their configurations. This is a random number and does not contain a facility code. ![]() MIFARE 2K PROGRAMING SERIALThe standard MIFARE card is factory programmed with a unique 32-bit serial number.A standard 1386 proximity card is 125KHz. MIFARE cards differ from standard proximity cards in three primary ways: They are durable and feature encryption keys to keep sensitive information safe and prevent data from being emitted until the MIFARE card and card reader mutually authenticate each other. Programmable access conditions permit complex applications and provide for future expansion. Securely separated sectors are each protected by a set of two keys. MIFARE cards provide the memory structure and capacity to store multiple applications on a single credential. MIFARE cards (originally developed for automated fare collection on European public transport systems) feature embedded microchip memory, which can provide identification, authentication and information. A proximity card does not have the capacity to store values. Typically used in access-control applications, proximity cards are also used to aid in crowd control.Ī proximity card’s embedded microchip has a simple and limited function: to provide the prox-card reader with the card’s ID number or a facility code number, which are then verified by remote computer (usually to grant access). Depending on the reader, the operating “reading” range for proximity cards is between 2.5” and 20” (63.5 mm / 508 mm). When the proximity card passes within range, the reader can read the card’s cardholder data. Proximity cards are read-only contactless devices with an embedded antenna. ![]()
