What a great comment. If I could overpay my karma into it, I would do so ten times. Thanks for the helpful tips. Most fobs I've encountered are the basic 125 kHz ones but some, like my garage keycard, are not. And I'd like to be able to amplify that signal because it's hard to get the garage in my condo building to detect the card.
Because it's passively powered, "amplifying" isn't really possible, short of replacing the access control reader.
With that said, if your badge is in tag/fob format, you could clone it onto a card-format. Larger antenna, better coupling.
