one emplementation i saw in one office was since barcoded id of person A can
be used by person B to login person A., what they did is they used a camera
to take a picture of the person login in. So that when there is some
anomally or what ever and they need to verify if the person A really did
come in that day they can check the picture. The verificationis still manual
but it will make people more honest :) and it does consume more disk space
(low quality image i think is enough).


My 2 cents,
John

Most of the serial and usb bar code 'gun' works well with linux. One
thing you can do is upon upong recognizing the bar code, a picture
will pop-up, along with the employees info. The security officer then
will recognize the irregularities.
