"Basic Knowledge of HF Band RFID" explains the effects of proximity to metal and countermeasures in an easy-to-understand manner in a YouTube video.
When a reader-writer (antenna) comes close to metal, communication performance (distance, area) may decrease. This is especially true when there is metal behind the antenna, as it is most affected by the metal. Therefore, we have created a video that explains the impact of metal proximity on the antenna and the countermeasures, and we are now releasing it.

basic information
1. About the Principle We will explain the mechanism by which the communication performance decreases when an antenna approaches metal. 2. Demonstration Through an actual operation demonstration, we will confirm that the communication performance (communication distance) changes depending on the presence or absence of metal behind the antenna. 3. Countermeasures We will explain the countermeasures to prevent the influence of metal. - Increase the distance between the antenna and the metal - Insert ferrite between the antenna and the metal - Optimize the antenna characteristics according to the installation environment

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