HID cards, also called prox cards, proximity cards & access control cards, are cards that use RFID embedded technology.
How do prox cards work?
Prox cards use a low 125 kHz radio frequency to transmit to a door access reader. When the card is placed on the reader, the card's unique strand of numbers is passed to the access control panel, which verifies if the number matches an approved number in the internal database.Jun 10, 2021
Is Mifare the same as RFID?
Mifare is a trademark of NXP Semiconductors for integrated circuits and reader modules. Mifare ICs are used in more than 1 billion RFID transponders. These chips comply with the international standard ISO/IEC 14443 Type A, which is widely used in contactless smart cards. In other words, Mifare is a brand of RFID.
Do smart cards use RFID?
Radio Frequency Identification (RFID) technology is used in many contactless smart cards. RFID Smart Cards store information on a chip embedded in the smart card. ... RFID induction technology is used for communication between the card and the reader and also powers the card.
What frequency is MIFARE Classic?
The frequency of a MIFARE card is 13.56 Mhz. A standard 1386 proximity card is 125KHz. The standard MIFARE card is factory programmed with a unique 32-bit serial number.
What is Mifare number?
Mifare Card Serial Number is the unique identifier defined in ISO 14443-3A. There are 3 types of UID defined in the standard - single (4 bytes), double (7 bytes) and triple (10 bytes). Only in first versions of the Mifare card, the UID was 4 bytes but now have migrated to 7 bytes.Feb 4, 2015
What is Mifare card format?
The Mifare card uses 48-bit keys (typically expressed as 12 Hex characters). There is one pair of keys, called the A key and B key, used to protect each of the 16 card data sectors. Each key in a pair can be used to protect a certain function.
Do proximity cards use RFID?
Both proximity and contactless cards employ the same fundamental technology–radio frequency identification (RFID)–for operation.
How do RFID access cards work?
The technology of Radio Frequency Identification (RFID) provides cards with unique codes imbedded on a chip to identify a card holder. ... When a card crosses the field, the power from the field energizes a copper wire inside the card, which powers the chip containing the card number and any other unique data.
What is the difference between a smart card and a proximity card?
A proximity card is used primarily for access, while a smart card provides a higher level of authorization for access. With the banking information stored on the chip, the user can make purchases, in either a contact or contactless manner.
Are proximity cards safe?
Proximity cards lack the security that you can achieve with other access control solutions. The low-frequency (125Khz) of the technology leaves a gaping hole for hackers and identity thieves to steal the unencrypted information. ... You don't “see” who's accessing your facility, so your security is compromised.
Can NFC read 125kHz?
You cannot read a passive 125 KHz Tag with a NFC reader, because as you have already guessed, they operate on different frequencies. There are passive RFID cards operating on 13.56 MHz, however, and these will read just fine on a NFC-enabled phone.
What is 125kHz RFID tag?
RFID is useful for sensing and identifying tagged people and objects for access control, automation, and a whole range of different applications. ... This basic RFID tag works in the 125kHz RF range and comes with a unique 32-bit ID. It is not re-programmable.
