The Keysy is a pocket-sized device for copying and emulating Low Frequency (125KHz) RFID tags. The device can hold four LF tags, which can be written off the device at a later time onto the Keysy LF tags.
Tag reading is simple and takes 20-30 seconds – place the device on top of the target badge, press a few buttons and it will be saved to the button slot you pushed. Tags can be immediately emulated / replayed or written out onto a physical badge.
With its discreet looks and card compatibility performance, the Keysy is another solid RFID tool for penetration testers.
