Designed to cater to a variety of needs, these NFC key fobs are perfect for anyone seeking a compact, reliable, and water-resistant solution for their access control and identification requirements. Each key fob has been constructed from high-quality ABS material, ensuring durability and resistance against environmental factors. At just 31 x 40 x 3mm, these key fobs are highly portable, making them easy to carry in a pocket or on a keychain. The inclusion of key rings further enhances their portability, allowing for seamless integration into everyday life.
Operating at a frequency of 13.56MHz, these key fobs are capable of both reading and rewriting data, which provides flexibility in various applications ranging from door entry systems to parking lot access. A notable feature is the UID changeable capability, enabling users to customize their key fobs based on specific requirements. Importantly, these key fobs have a reading distance that extends up to 10 cm, although actual performance may vary depending on the reader's design and environmental conditions. They are engineered to withstand harsh temperatures, functioning optimally within a range of -40°C to 65°C and having a storage temperature range of -25°C to 50°C.
The utility of these key fobs extends across multiple scenarios. For instance, they can be effectively employed in access control systems, making them an ideal choice for hotels, staff attendance, and educational institutions. Additionally, their potential use in municipal services and transportation payments signifies their expansive application range. Given their compatibility with all RFID readers, integrating these fobs into existing systems is a straightforward process. This makes them an indispensable tool for users requiring reliable access solutions.
Users have reported varied experiences with the key fobs, particularly praising their functional reliability at a competitive price point. The feedback indicates that these fobs work seamlessly with various equipment, including Mifare Classic locks and NFC-enabled devices. However, there are some caveats regarding the UID changeability; while technically capable of being changed, it requires specific tools and commands, which may not be user-friendly for everyone. Thus, individuals must ensure they are equipped with the necessary hardware or software to fully utilize this feature.
In contrast to standard RFID cards that may only offer single-use capabilities, these key fobs stand out due to their rewritable nature and water resistance, providing a distinct advantage in durability and flexibility. Similar products often lack the robust features that these key fobs present. For users seeking affordable yet advanced solutions, this product does provide an impressive mix of features at an attractive price. In direct comparison with budget options, these fobs offer better performance, especially for applications requiring frequent rewriting and data modification.
Overall, these NFC key fobs represent a practical choice for anyone needing a compact, water-resistant, and versatile access solution. Their blend of durability, functionality, and ease of use provides excellent value, particularly for those utilizing them in professional or educational settings. While some complexities exist regarding the UID programming, the overall reliability and effectiveness make them a solid addition to any access control system.
