The product is an RFID tag in the form of a key fob, manufactured by Promag under the manufacturer's number MTAG63. It is a passive, contactless identification module operating in the MiFare standard, intended for use in access control systems, identification systems, or other applications requiring contactless data transmission. The device is compactly designed and suitable for attachment to a key ring or other portable items.

Applications

The RFID key fob is used in systems requiring contactless identification over short distances. Typical applications include access control systems in offices, factories, or residences, where the fob functions as an electronic key. It can also be used in logistics and inventory management systems for identifying employees or items. Usage is exclusively in the 13.56 MHz frequency range, complying with the globally widespread ISO/IEC 14443 Type A standard.

Functions and Equipment in Detail

The device features a 1 KByte memory, intended solely for storing a fixed ID assignment. The function is implemented as read only, meaning the stored identification number cannot be changed or deleted. The ID is assigned at the time of manufacture and remains unchangeable. This makes the fob particularly suitable for applications requiring a fixed, non-tamperable identification. Data transmission occurs contactlessly via electromagnetic induction in the 13.56 MHz range.

Technology Explained Simply

The RFID tag operates passively, meaning it requires no internal power supply. Energy is inductively transferred from the reader during interrogation. This enables simple and maintenance-free operation. Communication occurs in the MiFare standard, widely used in many access systems and contactless payment systems worldwide. The 1 KByte memory capacity is sufficient to store a unique ID that can be recognized and processed by a reader. The technology is robust and enables fast, reliable identification.

Compatibility and Accessories

The fob is compatible with all readers supporting the MiFare standard (ISO/IEC 14443 Type A). This includes a wide range of access control systems, terminals, and scanners commonly used in industrial, office, and retail environments.

Mounting and Installation

Mounting is achieved by simply attaching the fob to a key ring or other portable item. No additional mounting aids or tools are required. Operation is contactless; the fob only needs to be brought near a compatible reader to transmit the ID. Integration into existing systems requires no special modifications, provided the readers support the MiFare standard.

Advantages in Operation

The RFID key fob provides reliable, contactless identification without mechanical wear parts. Passive technology ensures long service life with no maintenance. The fixed ID assignment protects against unauthorized changes to the identification number. Its compact form and robust construction make it suitable for daily use. Compatibility with widely adopted standards ensures easy integration into existing systems.
