Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. RFID is one method of automatic identification and data capture.
Unlike a barcode, you don’t need to search and read tags one by one, multiple RFID tags may be scanned and read via just a single RFID reader. As such, RFID technology can overwhelmingly shorten the time to count inventory.
As the UHF passive RFID (RAIN RFID) is capable of collective reading from a certain distance without a battery. In just 2017 alone, over 12 billion RFID tags were shipped worldwide.
While RFID is a useful technology, there was a problem in which a tag placed away from an antenna reader could not be detected and a reader’s accuracy on identifying the locations was low.
RFLocus achieves a 100% tag reading via our patented phase-based technology. Furthermore, we were able to specify the right and left position of multiple asset items in a shelf with an accuracy of 10 cm or less.
In comparison with the conventional approach using signal strength, RFLocus’s patented phase information technology reads more than 400 times per second. The technology herein uses all these collected data to compute for the tags’ positions relative to the reader in use. The resulting positioning information is not affected by tag sensitivity and reflection.
Our technology enables searching for items with RFID tags and automatically managing the position of all the items at night without any manual intervention. This saves labor and improves efficiency of work in counting inventory and searching for goods.
