ᐅ Keyless Entry Systems

But then you have to have the transmitter with you again.

I can see that I will have to deal with the implantation after all.
The owner will just get it injected on their next milestone birthday, possibly combined with a heavy drinking session.

Yes, but the transmitters come in various forms, such as key fobs for car keys or similar items. As long as you’re not walking around naked as a nudist, you can usually find something suitable.

Based on my recent experience, the fingerprint system is no longer an option for me...
It usually doesn’t work with dirty fingers. In my particular case (I do a lot of tinkering with old machines), this was a deal breaker for me and the system.

Depending on the security level of the system (in this case a business notebook from HP set to the highest security level), even a small cut on the finger can prevent recognition.
This might not seem directly related to the access systems mentioned above, but my point is that you should consider this as well.
HP acted quickly and issued a patch to improve recognition of, for example, injuries.
For a door access system, this would at least require an update—if one is available at all.
This is something to keep in mind during research, especially if you work in trades or similar fields.

With a fingerprint system, you can register each finger individually. If you cut one finger, you still have nine others. Or is the argument now “what if I lose both hands in a machine, but still want to get in”?
If your hands are dirty, just wash them. There’s always at least one finger clean enough. Otherwise, you’re going to damage not only the device but also your front door with all that oil.

We have a fingerprint system and it works great. We still have a regular house key as a backup to get in if needed. You can seal it and bury it in the garden, hide it under a paving stone, or place it somewhere else (like the back box in the shed), or leave it with your parents or wherever, so that you can still get in after 10 years in case of a power outage.

Of course, you can train any finger. But pressing the middle finger alone on the protruding pad was already awkward, and I gave up on the ring finger^^

When my hands are dirty, logically all my fingers are dirty, and often really badly so. “Just wash them” is not always something you can quickly do, and I don’t want to have to wash my hands every time I briefly enter the house. Most of the time I just grab an extra tool and keep working, so washing hands would be pointless. Besides, fingers often don’t get properly clean from just washing hands alone.
That’s why I prefer having a separate “workshop key” hanging on a lanyard. When I want to go inside, only this gets dirty, because I use it to open the door at the same time.

Again, I’m not trying to criticize or put the system down. That’s why I’m writing that FOR ME the system is no longer suitable. It just doesn’t fit my needs.

Our fingerprint scanner is flat, so there’s no awkward positioning needed. It even recognizes my finger when there’s a plaster covering half of the fingertip. However, I wouldn’t want to use the scanner with oily fingers, mainly because of the mess.

However, this also means that the system’s security is reduced in favor of recognition accuracy.
The larger the portion of the fingerprint scan used, the higher the security, but the comfort decreases because the frequency of rejections increases.
Partial fingerprints are left almost everywhere anyway, so personally, I would prefer higher security. Everyone has to weigh this for themselves if they think about it.
