Has anyone come across a solution to track the likes of a VMC or Telecom 'Air card'...
...when it's not connected?
Essentially it would apply to any PCMCIA card for that matter.
Is RFID really my only option? It's a bit unreliable with the devices (being mainly constructed of metal and generating quite a lot of interference)...without putting some sort of giant swing tag on them.
Any help?
