RFID/HID/Mi Fare Smart Card

RFID CARD-Contactless cards are proximity cards (these do not touch). These communicate with and are powered by the reader through RF induction. RFID cards, radio frequency integrated circuit (RFIC) card and MIFARE cards are all contactless cards. Low frequency smart cards are predominantly used in identification and access control applications. LF cards have lower read range and communication speeds than other contactless smart card types and the most common chips offer low-cost and low-security solutions where a simple UID or identification key is required. Due to the shape of their waves, LF cards are less affected by other radio signals and materials in the environment such as water or metal which makes them a reliable choice in industrial environments.

Mi-Fare Card-A contactless smart chip based device includes an embedded secure microcontroller or equivalent intelligence, internal memory and a small antenna, and communicates with a reader through a contactless RF interface. The contactless interface provides users with the convenience of allowing the contactless device to be read at short distances with fast transfer of data. A MIFARE card has a much larger memory than an RFID card and is widely used in hotels as payment cards and for identification purposes.
