A proximity card or prox card [1] also known as a key card or keycard is a contactless smart card which can be read without inserting it into a reader device, as required by earlier magnetic stripe cards such as credit cards and contact type smart cards. [2] The proximity cards are part of the contactless card technologies.
The integrated circuit outputs the card number to the coil which transmits it to the reader. The transmission of the card number happens in the clear—it is not encrypted. With basic understanding of radio technology and of card formats, Wiegand proximity cards can be hacked. A common proximity format is 26 bit Wiegand.
ISO/IEC 14443 Identification cards – Contactless integrated circuit cards – Proximity cards is an international standard that defines proximity cards used for identification, and the transmission protocols for communicating with it. [1] [2] [3] [4]
MIFARE is a series of integrated circuit (IC) chips used in contactless smart cards and proximity cards. The brand includes proprietary solutions based on various levels of the ISO/IEC 14443 Type-A 13.56 MHz contactless smart card standard. It uses AES and DES/Triple-DES encryption standards, as well as an older proprietary encryption algorithm ...
A contactless smart card is a card in which the chip communicates with the card reader through an induction technology similar to that of an RFID (at data rates of 106 to 848 kbit/s). These cards require only close proximity to an antenna to complete a transaction.
ORCHARD PARK, N.Y. — As Lamar Jackson spoke Sunday night, the Baltimore Ravens quarterback kept smacking his hands together as though he were awake, but trying to snap himself out of a bad dream.
The card stores a physical or digital pattern that the door mechanism accepts before disengaging the lock. There are several common types of keycards in use, including the mechanical holecard, barcode, magnetic stripe, Wiegand wire embedded cards, smart card (embedded with a read/write electronic microchip), RFID, and NFC proximity cards.
An Oregon man was arrested and charged Thursday for the murder of a car dealership owner who disappeared three years ago, police said Monday. Murphy Henry, 54, was also charged with abuse of a ...
