【Basic Knowledge of RFID】What is an RFID Reader/Writer? The Impact of Layering RFID Tags
We have created a video explaining the effects of stacking RF tags, and we will publish it. When RF tags are stacked, their communication performance decreases, making stable communication impossible. This is because the antennas of the RF tags overlap, and due to mutual inductance, the resonant frequency of the RF tags shifts towards the lower frequency. The degree of impact on communication performance varies depending on the spacing between the RF tags when stacked and the number of tags stacked. 1. About the principle Explanation of the principle behind the decrease in communication performance when stacking RF tags. 2. Demonstration Operational demonstration explaining the following content: - Stacking RF tags decreases communication performance. - The narrower the spacing between RF tags when stacked, the more communication performance decreases. - The more tags stacked, the greater the decrease in communication performance.

Company information
Founded in 1894 as a textile company, Takaya Textile expanded and established its electronics division in 1966, beginning the assembly of transistor radios. Currently, in addition to contract manufacturing services (EMS) related to electronic devices, the company actively manufactures and sells in-circuit testers (printed circuit board inspection devices), RFID-related equipment (technology that enables information exchange through short-range wireless communication from IC information tags), and engages in IT consulting and system solutions, among various electronics businesses both domestically and internationally. We will continue to evolve as a corporate group that contributes to the development of society, with textiles and electronics as our two pillars.
