An $80 padlock with a fingerprint scanner on it, which is touted as being able to be used outside, just got funded on Sharktank. Either they've got a new low-cost type of fingerprint sensor that can work when wet, cold, or dirty, or this was one of those ideas that are so good that non-technical investors will believe anything. They said one charge will last a whole year with 4 times use per day.
I don't think the product is yet available, but I wonder if IPVM can get a hold of one to test. Did anyone hear the inventor's statement of cost to build? Was it something like $20 bucks?
There is still a traditional hard key override that sits in the traditional place on a padlock. I think the key eill come in quite handy if someone expects this to work reliably outside or in applications where rowdy and typical kids in a school locker application won't let this thing stay clean to save their lives. It erases all stored fingerprints (up to 4) if an unregistered finger is presented more than 4-5 times I believe. Now .. where is that key?
