快三大倍投

END OF THE KEY?THE first doorknob with fingerprint recognition c

ould unlock the future... and make keys a thing of the p

ast. Users whose prints have been programmed into the devices memory simply brush a finger across it to o

pen the mechanism.

If the idea catches on, it could mean families would no longer need to carry traditional keys or hide them for neighbours. The BioKnob lock replaces an existing doorknob and, its makers claim, is more secure than a traditional lo

ck. It stores up to 100 sets of fingerprints which can be re快三大倍投 cognised by its in-built sensor and an audit feature records the last 1,000 uses. That means parents can tell what time children come home - and bosses can check on their workers timekee

ping. No pictures of fingerprints are recorded so no one can repli

cate prints from the data, i

ts makers claim. It runs on rechargeable batteries. The BioKnob was designed and developed by Tyc

hi Systems near Boston. Sheng Deng, the firms president, said: We wanted to bring biometric technologies mostly seen in g

overnment agencies to consumer products. It was a technological challeng

e but, after three years, we are delig

hted.  The BioKnob is available online, costs 255, and is available in silver or polished brass. m.swain@mirror.co.uk
