The ReinerSCT ACCS is an RFID transponder of type MIFARE DESFire EV3, specifically designed for use in time recording systems. It is delivered in a pack of 100 and serves as an identification medium for employees to accurately and securely record working hours. The technology is based on the MIFARE DESFire EV3 standard, developed for high security requirements in corporate environments. The transponders are suitable for use in contactless access systems and time recording solutions, particularly in combination with ReinerSCT systems such as the timeCard Premium series.

RFID Technology and Memory
The transponder uses MIFARE DESFire EV3 technology, a contactless RFID solution based on the ISO/IEC 14443 Type A standard. This technology enables secure and fast data transmission over short distances. The memory capacity is 4K bytes, sufficient to store multiple user profiles, access rights, or time recording data. The capacity of 70pF (picofarad) refers to the electrical capacitance of the antenna, which is crucial for the transponder’s functionality during communication with readers. This specification ensures reliable and stable signal transmission, even in environments with electromagnetic interference.

Applications
The transponders are primarily intended for time recording systems, especially in companies using electronic working time documentation. They can be integrated into systems based on the timeCard Premium platform and enable contactless identification of employees. Typical usage occurs in office environments, production facilities, or other workplaces where quick and secure presence control is required. The transponders are not intended for direct use in mobile phones or other devices, but exclusively for use with compatible readers.

Compatibility and Accessories
The transponders are specifically developed for use with ReinerSCT systems, particularly the timeCard Premium series. They are compatible with readers supporting the MIFARE DESFire EV3 standard. Compatibility with other manufacturers or systems is not guaranteed, as specifications and security protocols may vary. The transponders are used exclusively as replacement or additional transponders for existing systems.

Mounting and Installation
The transponders are pre-fabricated RFID modules and require no mounting or installation by the user. They are directly integrated into time recording systems by passing them over the respective reading points. Communication is contactless, with the user holding the transponder near the reader. No additional configuration or software adjustment is required, as the transponders are pre-equipped with the necessary firmware for MIFARE DESFire EV3 technology.

Operational Advantages
The use of these transponders provides high security through encrypted data transmission, making manipulation of working hours or access data difficult. Contactless communication enables fast and seamless operation, minimizing waiting times at reading points. The robust construction and standardization on MIFARE DESFire EV3 ensure long service life and reliability in daily operation. The transponders are used exclusively in closed systems aligned with MIFARE technology.
