rfid tag proximity RFID tags and readers have to be tuned to the same frequency in order to communicate. There are different RFID frequencies for public use: Low frequency (LF) 120 – 125 kHz: Older (less popular) proximity technology based upon inductive electromagnetic coupling.
The maximum overall NDEF message length is specified by the compatibility .

rfid proximity switch
Using RFID technology, a tag-based proximity warning and alert system identify personnel (wearing a tag) positioned within the vehicle’s proximity (or detection zone) up to ten . With an Active Tag, an RFID card can operate much further away, whereas a proximity card can only be read within a few centimetres. This opens up a whole host of uses for an RFID Card and subsequently, limits the use of proximity cards for .
Using RFID technology, a tag-based proximity warning and alert system identify personnel (wearing a tag) positioned within the vehicle’s proximity (or detection zone) up to ten metres away. Like the camera system, the driver is warned via an .

Active real-time location systems have tags that emit a signal every few seconds or minutes, and readers employ a variety of means to determine each tag’s location. Passive systems can tell you that a tag is within a read field. Choosing between RFID and proximity cards isn’t about picking a winner—it’s about finding the perfect fit for your needs. Consider your security requirements, budget constraints, and the specific environment where the cards will be used. RFID tags and readers have to be tuned to the same frequency in order to communicate. There are different RFID frequencies for public use: Low frequency (LF) 120 – 125 kHz: Older (less popular) proximity technology based upon inductive electromagnetic coupling.Contactless RFID tag technology is adding speed, accuracy, efficiency, and security to an ever-expanding range of RFID applications.

In this article, the authors describe existing problems with current RFID systems and survey potential solutions for proximity detection. They then present a new RFID device, called "Sense-a-Tag" (ST), that can passively detect .Proximity cards typically enable read-only capability while vicinity card or other RFID cards enable both read and write functionalities. The more widely used passive proximity card has a limited reading range and therefore must be held close to the reader unit.
If you want to detect a normally-not-powered passive type tag at extreme distances you have to power to that tag from a significantly bigger magnetic field. Making your magnetic field stronger is the only way I can know (and can recommend). One key distinction between proximity cards and RFID cards lies in their memory capacity. Proximity cards possess limited memory, whereas RFID cards offer expanded data storage capabilities. The amount of information stored within the .
