HACK a Passive RFID Transponder/ tag
I use an Amtech transponder to access my neighborhood. The signal strength is poor and the association isnt cooperating with me to have the system upgraded or to offer me a new style of transponder.
I opened one my my transponders and it appears to be a PASSIVE RFID device.
HOW CAN I MAKE A PASSIVE RFID TAG INTO AN ACTIVE TAG? I.e. HOW can I add a battery and/or larger antenna. ANY other suggestions that you can offer would be appreciated.
