Hidden camera rule #17: try not to put them in things that people intently stare at as soon as they meet you.
The AME-105 fake ID card gets a lot of things right—this disguise is in many ways ideal for spy-camming, as the circuitry, battery, 4GB of flash memory and 352x288/15fps video camera can all fit quite naturally into the body. Unfortunately the concept falls flat when you realise that your nametag is probably the most-eyeballed item on your body body. The tiny text won't exactly help matter either.
Sadly for those who make their living spying on incredibly inattentive and/or senile people, the AME-105 is only available in Japan. [Akihabara]
