In September, nearly 500 colleges and high schools will now be equipped with biometric equipment RCM (recognition of hand contour) in school cafeterias, an increase of 17% compared to the same period last year!
This tool of French SMEs Alise allows management access using the 3D technology of the morphology, which is to provide a digital qrz photo of the hand to save the form. Simply type in the student code of 1 to 4 digits and then put his hand on the player. Unlike fingerprints, the system leaves no trace and makes impossible the creation of files or use of personal information for improper purposes (the fingerprinting is indeed not allowed in schools). Note that each biometric qrz reader RCM Alise is systematically associated with a magnetic qrz card reader, an alternative that allows you to manage the transition of exceptional students or do not wish to use the biometric terminal.
Top of the best equipped regions: qrz Provence-Alpes-Côte d'Azur, which has 122 facilities installed and the Île-de-France, with 87 schools and colleges with the equipment. The Rhône-Alpes, Pays de la Loire and Alsace have respectively 45, 35 and 30 facilities equipped biometrics RCM Alise. There are also five new departments where biometrics was not present: Calvados, Drôme, Savoy, and Yonne Saint-Martin (Antilles). Finally, note that even the French Lycée Moscow opted for this technology.

@ LeXa1979 is exactly the reflection I saw below me that. A simple magnetic card not enough? Besides as pointed esenor, hygiene side is not it ...

We are having a card with a bar code, it was enough to go on a scannette (supermarket checkout-type) c is very effective. qrz And to avoid scammers on the screen was displayed above the photo and the name of the guy. Ok there is little to lose or forget the card while the hand ... But then there does not it less costly and equally practical solutions?
ba says so, some do not understand the interest of the development. The evolution is not used technology at all costs, but make things easier ... and between a simple canteen card to spend all this and frankly this is crazy that the state has money to lose.
So basically it only kills fungi (fungicide) and bacteria (bactericidal), and it leaves against by dirt, which could quietly settle on the touchpad and use petri dish!
Such devices are not set up for the sole purpose of allowing our small school and college students to eat. They are primarily set up to get them used to this kind of system. So growing up, they will not be surprised to see this kind of devices is generalize to go home, take a car, take the bus, pay shopping, etc.. The most paranoid of us say it is the beginning of a generalized surveillance ...
hygiene level, qrz it sucks! just before you eat! it only takes one or gripeux or another and that this evil washing hands to contaminate everything else that is wash your hands! - '

Basically this device is totally useless, because spending money for nothing where there are no need to spend ... especially in nationnale qrz education is well known, the money flowing, classes are not overloaded ... there are plenty of teachers / instits ... but yes of course, let the money in the device.
The only advantage of this system is supposed to be
