The UHF stationary 4 channel RFID reader has the highest performance recognition distance and the best multi tag recognition performance. This is ideal for recognizing hundreds or more tags. It also has the ability to read only the desired tag using visible beams. This function is a technology invented by IDRO Co., Ltd. It is a function to intuitively select and read a tag by illuminating the tag to read. This technique is especially useful when you want to read only one tag when multiple tags are adjacent.

In the conventional RFID technology, when a plurality of tags are positioned adjacent to each other, unwanted adjacent tags may be read, resulting in a system error. This is one of the major disadvantages of the existing RFID technology. In order to reduce these errors, the conventional RFID system requires very complicated and time-consuming operations such as very precise power control and shielding installation.

However, Visible RFID technology with ID is a solution to this problem.

It is a system that can solve this problem by simply shining a light on the desired tag. This function is particularly useful in process management, kenveer applications, and facility management. In such applications, using Visible RFID technology instead of using the existing RFID technology can dramatically reduce system errors caused by the recognition of unwanted adjacent tags.

The IDRO Visible RFID Reader also supports the existing ISO 18000-63 / EPC Gen2, so you can select the functions you want.
