Global Proximity Reader Market is segmented, By Type into Active Proximity Reader, Passive proximity Reader. Proximity Reader is a Type of RFID technology i.e. it is a Radio Frequency Identification, which is an access control device controlling an electronic work lock; which could be like stripe, voice recognition, magnetic stripe, barcode, and the other automatic identification technologies. Within a few inches, the reader will pick up the signal by the card which the employee can use or bring it. Also, it doesn’t have to be swiped. Plus, it is unlike magnetic bar code badge, which drives its popularity. It is very simple and employee can bring this card in his wallet which helpful.

The proximity readers transmit the low-level fixed radio frequency (RF) signal rapidly that provide energy. The card is having unique identification code in its microchip. This microchip is powered up by the small coil in it that power ups the signal of RF absorbed by the coil from certain distance from reader. This whole process takes a microsecond or fraction of seconds. The card transmits the code to the reader only. It is simple technology; which is an advantage to the other technologies. Also, there are no slots, no read heads, mechanical wear, no parts to maintain.

In the active proximity, there is a battery inside the card. The card has a power in the range that is greatly expanded (3-15 feet vs. 1-5 inches). The frequency used is much higher, but the RF signal is low level (
