Security device (10) for online transactions between service purveyor computer (15) and an operator equipped with a computer (16, 18). The device comprises a photo-electric sensor (22) that is applied to the screen (16) of the computer to identify a matrix signal from the purveyor computer which is then processed to generate a code and communications means that allows it to be accessed by the operator. The device also comprises a biometric sensor, particularly a fingerprint sensor with which data relative to the operator are input. Encryption means are provided between the photo-electric sensor and the communications means that ensures the code determined from the screen is only accessible if the fingerprint matches the one stored in the card. The security device is credit card sized and has an independent power source. |
