125 Khz Badges - Access Control System

The badges working at 125 Khz frequency has the advantage to be simple (and cheap, too) and to provide a good reading distance.
The cons are the disadvantage of not being a standard, not have appropiate security systems and not manage the collisions.
There is different kinds of proximity badges working at 125 Khz frequency:

  • Just reading (EM400x) with 40 bits
  • Writable emulating the only reading badges working (also in this case with 40 bits)
  • Titan with 1 Kb capacity (more expensive with a proprietary format)
  • HID; badge con with proprietari technology, non not duplicable and available in different formats
  • other less popular typologies
