초록

A portable fingerprint recognition transmitter that is compact, being less than the size of a cigarette pack, allowing the fingerprint recognition transmitter to be carried by an individual in a pocket or purse. The fingerprint recognition transmitter operates to take the image of the fingerprint and formulates a fingerprint image capable of transmitting through infrared or radio frequency to a receiver having previously stored fingerprint images so as to cause a comparison between the image taken and the image stored for purposes of unlocking a security...
