Biometric Padlocks, Do They Work?

Anyone used a fingerprint padlock?

Home Depot is selling this one, from Talon.

But this Kickstarter one seems cooler (not shipping till Fall):


Personally I did not try this model but heard that it is not reliable enough for "outdoor" (outdoor meant a locker inside of detached garage) usage.

I had a project where fingerprints were used for the access to personal lockers in the industrial environment. It was not an off-the-shelf lock neither a mentioned padlock but the idea was the same. Despite the fact that fingerprint sensors were from the reliable vendor, within a year, customer has made decision to change all sensors to keypads because of employees' complaints.

Thus I can say that if somebody will lock his bar with it then it should be fine. Otherwise I would think twice.

I would wager an old fashioned dial combo lock can be opened faster after a few months.

I could zip open my High school lockers in seconds (to get to the Ray-Bans). However, I can run my finger over my stupid laptop fingerprint sensor using a similar sensor type for ages before giving up and just typing in my password.

But, what was your combination? ;)

Well, I do actually remember it. It was a combination of the engine size of my car, and the last three digits of my beeper number.

All these electronic padlocks seem to fail-secure when the battery dies, which is a pain. They need some sort of inertial charging, like self-winding watches have, so you can just slam the lock back and forth 20 times and it will come to life.

Do you think there is internal Wiegand going on?

I highly doubt it. Being a SOC and using a proprietary sensor mean that whatever protocol they are using is fast and optimized for their design.
