What Is an RFID 1K F08 Key Fob?
An RFID 1K F08 key fob is a small contactless RFID device using a 13.56 MHz F08-compatible chip. The chip communicates with compatible RFID readers without requiring physical contact, allowing the key fob to be used as an identification credential.
The 1K designation generally refers to approximately 1 KB of EEPROM memory. A MIFARE Classic 1K-compatible structure is commonly organized into 16 sectors, with each sector containing four blocks. Depending on the specific chip implementation and application, memory can be used for identification data, access-control information, or other application data.
Unlike a standard plastic access card, a key fob is designed around a compact form factor with an integrated hole for attaching it to a key ring or other accessory.

13.56 MHz RFID Technology
The RFID 1K F08 key fob operates at 13.56 MHz, a high-frequency RFID band commonly used for contactless identification applications.
When the key fob is placed within the operating range of a compatible reader, the reader generates an RF field that enables communication with the chip. The user does not need to insert or physically connect the key fob to the reader.
This contactless operation makes the format practical for doors, gates, employee identification points, lockers, and other locations where users need fast and convenient credential presentation.
The actual reading distance depends on the RFID reader, antenna design, installation environment, chip configuration, and key fob construction. Therefore, a fixed read distance should not be assumed for every installation.
F08 Key Fob vs. 125 kHz RFID Key Fob
One of the most important factors when selecting an RFID key fob is frequency. A 13.56 MHz F08 key fob should not be confused with a 125 kHz proximity key fob.

|---|---|---|
| Frequency | 13.56 MHz | 125 kHz |
| RFID Technology | HF RFID | LF RFID |
| Typical Chip | F08 / MIFARE Classic 1K-compatible | EM4100 / TK4100-type |
| Typical Use | Access control, identification, NFC-related applications | Basic proximity access systems |
| Memory | Around 1 KB in typical 1K configurations | Usually limited or read-only depending on chip |
| Communication | Contactless | Contactless |
| Reader Requirement | 13.56 MHz compatible reader | 125 kHz compatible reader |
| Interchangeability | Not interchangeable with 125 kHz systems | Not interchangeable with 13.56 MHz systems |
Before ordering, always confirm the frequency and chip technology supported by your existing RFID reader.

Data Capacity and Memory
A typical MIFARE Classic 1K structure provides 1 KB of EEPROM memory organized into sectors and blocks. However, not all of the nominal memory is necessarily available for general application data because some memory areas are reserved for system information and security functions.
For this reason, the usable capacity should not be described simply as the full nominal memory size.
If your application requires storing data on the RFID credential, confirm the actual available memory and data structure with the chip supplier before production.
Read and Write Performance
The key fob communicates with a compatible RFID reader through electromagnetic coupling. No battery is normally required for this type of passive RFID credential.
Read performance depends on multiple factors, including:
- Reader output power
- Reader antenna size and design
- Key fob orientation
- Distance between the credential and reader
- Presence of metal or electromagnetic interference
- Housing material
- Installation environment
Consequently, the actual performance should be validated using the final key fob and the intended reader rather than relying only on theoretical specifications.
