What is the difference between RFID and HID?


What is RFID card format?

  • It is commonly classify into three kinds that are Mifare, EM Proximity and HID. Rather than magnetic stripe cards, contactless card that allow us to tap / put near the card reader for a moment to enable the identification of card number. Typically, it can easily read the card a distance about 5 to 10 cm range.

What is the difference between RFID card and HID?

RFID (Radio-Frequency Identification) card formats refer to the standards or specifications used to encode information on RFID cards. The format determines how data is organized and stored on the card's RFID chip. There are various RFID card formats, such as:

  • EM4100: A common low-frequency (125 kHz) format used for access control, identification, and tracking.
  • HID Prox: Another popular low-frequency (125 kHz) format by HID Global, widely used in access control systems.

  • MIFARE: This is a high-frequency (13.56 MHz) RFID format developed by NXP Semiconductors. MIFARE cards are prevalent in public transportation, access control, and contactless payment systems.
  • iCLASS: An advanced contactless smart card technology developed by HID Global, operating at 13.56 MHz, used for access control and other applications.
  • DESFire: Also developed by NXP Semiconductors, DESFire is a high-security contactless smart card format operating at 13.56 MHz. It's used in applications requiring high levels of security, such as payment systems and government IDs.
  • Each format has its unique specifications, including data structure, encoding methods, security features, and supported applications. Understanding the format is crucial for compatibility between RFID cards and the systems that read and interact with them.
