## Summary description

RoGer EMC-4 is a proximity RFID access card with a modifiable UID designed for contactless identification at 13.56 MHz. The card serves as an access credential for readers and control systems that accept rewritable UID cards. It is suitable for building access control, time attendance systems, and secure area authorization where replacing or cloning UID is required.

## Long description

RoGer EMC-4 is a 13.56 MHz proximity RFID access card with a modifiable UID designed for contactless identification. The card operates as an access credential compatible with readers and control systems that accept rewritable UID tags, enabling flexible assignment and replacement of credentials for access control and time attendance. Its slim, card-format design fits standard cardholders and wallets while supporting common contactless workflows for building and facility entry.
Advantages
The modifiable UID allows administrators to reprogram the card to match existing UID-based systems without replacing physical media, reducing logistics and inventory complexity. Operating at 13.56 MHz offers compatibility with modern contactless readers and improved read stability compared with lower-frequency alternatives. The ISO-sized form factor and durable PVC construction provide reliable daily use and easy integration into access or attendance systems.
Suitable for
Access control systems requiring rewritable UID cards
Time and attendance terminals with 13.56 MHz readers
Secure areas where UID replacement or cloning management is needed
ID card holders, employee badges, and visitor management
Key specifications
Operating frequency: 13.56 MHz
Form factor: ISO credit-card size (PVC)
UID: rewritable/modifiable
Contactless communication: proximity RFID
Typical use: access credential for compatible readers and control systems
How to use
To use the RoGer EMC-4 card, program the UID using a compatible writer or configuration tool following the reader or control system manufacturer's instructions. Present the card to a compatible 13.56 MHz reader at the standard operating distance; the reader will authenticate the card based on the programmed UID. Store and handle the card like a typical PVC access card, avoiding excessive bending, heat, or exposure to strong magnetic fields to maintain functionality.
Usage recommendations
Before deployment, verify compatibility with your control system and test the programming procedure on a small sample. Maintain a secure process for UID programming and tracking to prevent unauthorized cloning or credential misuse.
