RFID Key fob Tags with 13.56 MHz F08 4k Chip
(Product ID: 3579)

RFID Key Fob Tags with the Fudan F08 4K chip are suitable for readers operating at a frequency of 13.56 MHz, following the ISO14443A protocol, and can write specific data to memory.

These key tags are special because they contain chips with larger memory than standard 13.56 MHz tags like Mifare Classic 1 kB or Fudan F08 1k chips.

These key fobs with larger memory are also suitable for systems that require only 1 kB of memory and systems that do not use memory at all but rely solely on the factory-programmed chip ID code for identification.

An example of using RFID key tags with a 13.56 MHz F08 4k chip is access control devices that require 4 KB of memory. The memory is typically used for transferring user and transaction data between the standalone access control device and a computer.

Fudan F08 4k chips are significantly more affordable than other chips with the same memory size.

We have gray key fobs in stock, other colors and personalization is available upon request. We can also number or print tags with a logo.
