TAG-6 RFID 125kHz 13.56MHz Unique Access Keychain



The RFID access fob TAG-6 125kHz 13.56MHz unique from the Spreest brand is a dual-system identification medium combining 13.56 MHz MIFARE Classic 1K (S50) and 125 kHz EM-ID technology in one housing.
Thanks to the integration of two popular standards, the fob is compatible with both HF and LF devices, making it a universal solution for access control systems, time and attendance, intercoms, and hybrid installations.
The 13.56 MHz part allows programming of memory sectors according to the MIFARE Classic 1K architecture, while the 125 kHz chip has a factory-written and unchangeable ID. Both modules operate in parallel, and their inviolable identifiers ensure stable, repeatable identification in systems.
Due to the design of the MIFARE S50 and EM-ID systems, neither UID/ID can be changed – the fob is not a copyable medium.

Key features
- Dual Technology HF + LF: supports 13.56 MHz (MIFARE Classic 1K) and 125 kHz (EM-ID) systems
- Media copying: none – both identifiers are factory-secured and unchangeable
- Programming: 13.56 MHz – ability to edit sectors, blocks, and keys excluding sector 0; 125 kHz – no programming capability (fixed ID)
- UID/ID: identifiers in both systems cannot be changed
- Communication standards: ISO/IEC 14443A (13.56 MHz), EM-ID (125 kHz)
- Format: ABS keyring with metal ring, durable and compact
- Application: access control systems, time and attendance, intercoms, user identification, hybrid systems
