Why are locks with smart cards (RFID) not used for apartment doors?

Do it yourself

Sometimes I forget something at home - I have to go back, unlock and lock a bunch of locks.
Why do we still suffer from obsolete mechanical locks?
Why are electromagnetic and electromechanical locks with RFID keys bad? After all, in the event of a power outage, you can build a backup battery.

Why not? Buy two readers, a Z-5 controller, an electromechanical lock (it will cost you $50-100) and use it, it just hasn’t become a habit, wait a bit, in 10-15 years everyone will forget about such anarchism as a door key =)

A regular RFID tag is too easy to copy without you even noticing it. Copy devices are sold, there are open-source schemes. Making a lock that opens the door using an access card, and then storing the card in a foil pocket is somewhat strange :)
Modern intercoms sometimes use RFID tags in the form of key fobs, but intercom doors have a slightly different task.

My friend set it up ... or rather, they set it up and set it up for him.
They put an electromagnetic lock, it opens from the inside with a “handle”, and from the outside with a key (mechanical) or an em-marine card. In the event of a power outage, the controller with the reader is cut off (it has a power supply with a battery), and the lock remains closed. The reader can be made hidden (disguised under plaster), then you get a door without a lock. This door is harder to break.
Castles are of different types. The best choice for an apartment is an electromechanical lock, which looks like a regular one, but with a solenoid.

And, by the way, what to do with such doors if the light is cut out in the house?

By the way, there is a combi system of an electronic lock plus a key - if the electronic lock is dead, you can open it with a key

I have an idea to put an electric bolt and a combination lock on the IR. The key itself will be in the form of a cigarette with an LED on the end. He stuck it in the keyhole, he fired a code message. The castle opened. For backup power to the lock, bring the contacts to a couple of nails with which the upholstery is nailed.
Simple, but any pro burglar will break off to open such a door.

In 90, he did such a thing to a friend - switches were disguised under the carnations of the door upholstery. By pressing in the desired sequence, the alarm was turned off and the solenoid pulled the valve. All this was in addition to the existing mechanical lock. The person left often and for a long time and was worried about his apartment

Google said that there are such locks, so someone yes uses them.
I would love to use one card to access home/work.
But if you need to leave for a couple of weeks, then it is better to use a couple of mechanical locks ...

I think this is most of all due to the inertia of thinking: a simple lock, regardless of its type, is understandable to an ordinary person, because mechanics has been used for more than a century :), but here you need to figure out how reliable it is, how to use it, etc. etc. In addition, I don’t see the point of putting one at home, if a pro thief needs something, no lock will save, and standard means (an iron door and a “regular” lock) will save from an accidental drug addict.

Reliability and simplicity. That's all.

Now sometimes combination locks are also used, with buttons under the panel so that the dialed code is not visible. Sometimes I want to put myself one, if it has a cord for remote control and a digital home, it will be generally good.

Why not? Enough of these castles. out in google on the first page a pack of links

Such locks are actively used in enterprises when many keys can be distributed and, if anything, selectively activate / deactivate the key. Plus control when someone came in and out.

The main thing is that the light would not be turned off and the uninterruptible power supply would be enough.

In the event of a fire, electricity will be cut off. What to do in case of electric lock?

How do readers relate to stun guns? Suddenly someone wants to "annoy"?
