I work for an entity that implements physical security for pretty much everything. Workstations in the office can even have their own badge reader (through "Imprivata") to "login". One group of employees we cater to absolutely uses these systems to keep notes, and to be able to move from one office to another quickly and effectively. The badge access systems make "authentication" quicker and slicker.
I wanted to make it even easier than reaching for my badge to tap in and out of the computer, so I bought a T5577 RFID writable ring off of Amazon, and an RFID reader/writer. At first, I got fairly frustrated that neither of those tools did what they were supposed to do.
Then I made one adjustment, and things were suddenly magic.
So, what did I do?
Use the mode key to select "HID 125KHz".
Once the HID 125KHz is selected, insert the badge, and press "read".
The device will then say to put the T5577 card in and press "Write". This will take some trial and error to find the right position to hold the ring for writing.
Once you have a successful position and press write, it will tell you it was successful.
With that, it was time to test it. At a workstation, I used my primary badge, and locked the session. Then I tried with my hand (ring) to unlock, and the light indicator went to "green" from "red", showing success.
The workstation unlocked, angels sang from the skies above, and I was suddenly being served pina coladas on a beach in Tahiti. (Well, one of the three was true.)
