Great invention or bad one

I think it is a good idea as it may reduce the number of burglaries, but if someone wants to break into your house they will do it anyway with or without a key. also if someone hurts you at the door you will probally have to be consious as lifting an unconsious body is harder so you will be able to see the person doing it, with a key they can knock you out and take your key.

First of all I did not heard about such invention. But as U told if it is so, according to me, it is not practical for day to day life. Yes it should be useful in higly secured area, where finger prints of paricular person is a key to open the secured room.

I dont think i is a that good an idea. That is true. What if someone hurts you at the front door. Everyone dosent have the same fingerprint and there might be many members living in the same household.It would be better if the finger print of only one finger is taken to open the door and trying more than 3 times will fail the lock completely. I still dont think it is a good invention. Numbersystem is a beter method.

I think its not that bad idea to have the finger prints, its far better an invention than some of the earlier ones.... i meant with the inventions which are causing this Globalwarming of all sorts
