Clamshell cards, a distinct type of RFID (Radio Frequency Identification) device, have become increasingly prominent across various industries. Their unique design and functionality set them apart in the realm of access control and identification.
The name “clamshell” perfectly captures the physical appearance of these cards. Comprising two layers of durable material, often plastic, that are sealed together around the edges, they form a protective enclosure reminiscent of a clamshell. This construction shields the internal RFID components, which typically include an antenna and a microchip. The chip holds the all-important identification data, while the antenna enables seamless communication with RFID readers.
Among the different iterations, the RFID thick card is a notable variant. Its sturdier build makes it highly resistant to bending, abrasion, and even accidental impacts. This robustness is invaluable in industrial settings or outdoor environments where cards may be exposed to harsh conditions. Whether it’s a construction site or a large outdoor event, the thick card can withstand the rigors of daily use.
Clamshell proximity cards, on the other hand, are centered around the concept of proximity sensing. They utilize RFID technology to enable contactless access. When a user nears an access point outfitted with a compatible reader, the card’s antenna detects the reader’s electromagnetic field. Instantly, the microchip wakes up and transmits its unique ID. This allows for quick, effortless entry, eliminating the need for manual key insertion or code punching.
In access control systems, clamshell cards offer enhanced security. Each card has a one-of-a-kind identification code, which is difficult to duplicate. Moreover, access rights can be easily managed from a central console. Administrators can revoke or modify access privileges in real-time, ensuring that only authorized personnel can enter specific areas.
In ticketing applications, such as for concerts or public transportation, clamshell cards simplify the entry process. They can be scanned rapidly, reducing queues and congestion. Additionally, they can store extra information like seat numbers or travel itineraries, enhancing the overall user experience. Whether it’s safeguarding a building or streamlining event entry, the clamshell card stands as a reliable, multi-functional tool.
Clamshell Card(Thick Card), is one of the card in competitive price and widely used in many industrials, such as Car Parking, Access Control/ Time Attendance, Piece Work, Patrol System etc.
