In the image you can see the setup I want to have. Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. Battery-powered RFID tags are embedded with small batteries that power the relay of information. Passive, Active and Semi Tags "Passive" tags have no power source but use the electromagnetic waves from the reader to energize the chip and transmit back (backscatter) their data. A passive RFID-based location system for personnel and asset monitoring. Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. They leverage a battery that can be used to power on-board microcontrollers and extra sensors, i. Our equipment is used for access control, asset management, time and attendance and mass evacuation. Thanks for your interest. But I am not sure which company manufactures it or what will be cost of such RFID reader. ELA Innovation offers a wide selection of long-range active RFID products to satisfy all your identification project needs. Battery for Tag : Available : Not Available : Tag power requirement : continuously available : available in the range of RF field of the RFID reader : required signal strength from reader to tag : Low : High. As high-performance, multi-protocol devices, the UHF RFID passive Readers are compliant with EPC Gen2 (ISO18000-6C) and ISO18000-6B standards. Active tags can be picked by RFID readers from a range of 60-100 feet in most operating environments. Aloof RFID systems can work in the low recurrence (LF), high recurrence (HF) or ultra-high recurrence (UHF) radio groups. Passive RFID systems are commonly used to track inventory assets in retail applications, to monitor goods in a supply chain, to identify products such as pharmaceuticals, and to add RFID capability to a wide range of devices. The passive RFID tag returns a signal that is a 96-bit string of data which identifies the asset. If you use ISO15693 tags (which the 4mm x 4mm tags are!) then you can also use a lock block command to keep the data permanently stored so no one can overwrite it - I think that would be very useful for your use case. I used an RFID reader from Trossen Robotics.
