Glad you reactivated your project and had some good news to share! Thanks for the update!
Whatever you can share will be great news for anyone else just starting!

Hello Buzz and Trey.
Thanks a lot for sharing the solutions. I just "reactivated" my RFID project (a lot of work in last months) and found your solutions to my issue really helpful.
- Changing from 5.0V to 3.3V the circuit Vin, It works like a charm! Really strange but I red from the new edition (11.04.2013) ID-Innovations datasheet, the following: "The choice of power supply is very important. The ideal power supply will be a linear type such as an LM7805 or a 3.3 volt equivalent. Batteries may also be used without a regulator, a suitable arrangement can consist of a 3volt lithium cell or 3x 1.5v cells to give 4.5 volts." It seems that the Trey got it at first! ("Gerardo This almost sounds like a power issue.").
- Now it seems that the new release of ID-2/12/20 series (LA) is Low power working range from 2.8 to 5.0 volt. But may be the previous ones were too? Do not really understand. I will send them the video, the circuit powered at 5 (during locking) and the working one powered at 3.3. I'll let you know their answers.
Chris may the 3.3 Vout be more "linear" and stable than 5.0 Vout?
