We will explain the features of RFID and what can be done with RFID for customers considering its implementation.
The HF band is an abbreviation for "High Frequency" and utilizes a frequency of 13.56 MHz. The HF band has a short communication distance and is used in various fields due to its stable communication performance and high security. HF band RFID is a short-range wireless communication technology that uses the 13.56 MHz frequency band. This technology employs electromagnetic induction and is less affected by moisture and metal compared to UHF band radio waves. Therefore, although the communication distance is relatively short, ranging from about 5 to 70 cm, it is widely used in situations where stable communication performance is required. Despite the short communication distance, it allows for high-speed data transfer and is suitable for applications where security and individual authentication are important. Common examples include personal authentication with transportation IC cards and basic resident registration cards, as well as specimen management in healthcare and surgical instrument management. These technologies demonstrate their convenience in everyday life and industrial fields. Furthermore, NFC (Near Field Communication), which is incorporated into smartphones, is also a type of HF band technology. NFC is widely used as an important technology supporting modern digital life, such as cashless payments and data sharing.

basic information
Four Features of HF Band RFID Communication Distance The communication distance is relatively short, ranging from about 5 to 70 cm, making it suitable for applications that require one-to-one item authentication, thus reducing the risk of reading unnecessary tags. Resistance to Metal and Liquid Environments The HF band uses electromagnetic induction, making it relatively resistant to the effects of moisture and metal. High Data Security HF band RFID adopts standardized protocols such as ISO/IEC 14443 and FeliCa, utilizing advanced encryption technologies to prevent unauthorized access to data.

Applications/Examples of results
Manufacturing By attaching RF tags to work instruction sheets and holding them up to an antenna, the start and end times of work can be recorded, allowing for real-time tracking of progress. The introduction of RFID reduces the burden of handwritten daily reports and improves the accuracy of progress management. Healthcare By attaching RF tags to medications, the flow from dispensing to administration to patients can be recorded, enhancing the accuracy of medication management. This simplifies the management of medication usage history and expiration dates, reducing the risk of medication errors. Library By attaching RF tags to books, the lending and returning process for multiple books can be handled simultaneously. This reduces the time required for tasks compared to the traditional barcode method, improving user convenience. Additionally, the RFID gate system installed at the library entrance issues a warning if books that have not been checked out pass through, helping to prevent loss or theft of books. The gate is also equipped with infrared sensors, allowing for the counting of visitors.
