RFID Keychain is a portable tag that integrates a radio frequency identification (RFID) chip and antenna, and its physical form is designed to be easily hung on a keychain. It is a data carrier for automatic identification and target tracking. RFID keychainsare designed to be extremely portable. Through the hanging ring at the top, it can be integrated with the user’s keys, backpack and other daily belongings, ensuring that they are at your fingertips when needed, greatly reducing the possibility of loss. This is in sharp contrast to other RFID tag formats such as card and wristband.
Not all rfid keychains are the same, and their performance and application scenarios are mainly determined by their operating frequency:
Low frequency rfid keychain frequency is 125 kHz, strong penetration, can effectively penetrate non-metallic materials, anti-liquid and human interference ability is excellent. But the reading distance is very short (usually 10 cm). Typical applicationsinclude access control systems and animal identification. Because its signal is stable and unaffected by the surrounding environment, it is ideal for safety-critical applications.
The high-frequency rfid keychain frequency is 13.56 MHz, the reading distance is moderate (a few centimeters to one meter), the data transmission rate is fast, and it supports high security encryption and more complex data interaction. This is the frequency of the most common access cards, membership cards, library book labels. It also supports NFC technology, which means your HF RFID keychain can interact with NFC-enabled smartphones for identity verification or information transfer.
UHF rfid keychain frequencyis 860-960 MHz, long reading distance (up to several meters or even ten meters), fast group reading (can identify hundreds of tags at the same time). But the signal is easily absorbed or reflected by liquids and metals. Typical applicationsinclude logistics and warehouse management (attached to pallets or containers), vehicle management (parking lots, toll booths, no traffic), retail inventory. UHF rfid keychains are often used in industrial scenarios where long-range, high-volume identification is required.
In order to adapt to different environments, the keychain has a variety of shapes and materials, and can be designed into any shape-company Logo, product outline, mascot, etc., becoming a powerful brand promotion tool. In addition to the common ABS plastic, there are metal,wooden, leather,or silicone keychains to meet the tonality of different brands and the aesthetic needs of users, and enhance the value of gifts.
In addition to access control, RFID keychains extend more unexpected innovative application scenarios:
In a large factory or repair shop, every expensive tool comes with a sturdy RFID keychain. When employees borrow and return, they only need to swipe the toolbox in front of the reader, and the system can automatically record, greatly improving management efficiency and accuracy.
In the themepark and museum, the visitors buy a special nfc keychain, interact with different attractions in the park, collect electronic seals, and finally generate personalized tour souvenir books.
In the retail: The brand uses the rfid keychain as a member voucher, and customers can touch the sensor with the key chain in the fitting room to get more product information or call the clerk service.
In Pet management: In addition to implanted chips, RFID keychains worn on pet collars are also effective identification, which is convenient for shelters or veterinarians to quickly identifypet birth, vaccination and other information.
