Where to buy NFC enabled locks?



  • Guys, this just made me think. If you could get a hold of an android phone that was used and had NFC, or a junked phone that could be setup with OTG and a USB NFC reader, it seems you could mount the phone next to the door on the inside, maybe near a light socket, then the reader could be opened to extend it's antenna. If you ad a doorbell,you could easily modify the top plate that came with the reader to fit behind your doorbell plate and wired through it's hole. If you do have a light switch even the res of the reader could be mounted behind the wall and could provide both with power. The cool thing is that with something like tasker and the phone, when you tapped your ring the app would send the command through your home network. to unlock the door, or lock if it's not already so. the phone itself could act as a screen at the door. Home page could have a time/temp widget and the tasker buttons to unlock/lock the door. A swipe one way could reveal a running grocery list, another swipe for to-do list. just got me thinking.

    Personally I see that as just about the most difficult way to do things, mostly because mobile phones don't enjoy being modified like that. I mean, it's doable, but your milage really is going to vary based on so many different things including how skilled you are with an iron and exactly how heavily you modify the phone.
    By the time you're done it would perhaps have been easier to use one of the elechouse PN532 units with an arduino instead.



  • I wasn't thinking of modifying the phone at all. just to use it as a go between for the lock and a US NFC reader running off the micro-USB OTG. The rest of my crazy was just mounting ideas.

    Ah, fair enough. I'm operating from the viewpoint that the NFC reader in the phone is far less sensitive than the $10 pn532 reader I got from ebay is all, so you'd have to do something to extend/retune/rematch the stock phone antenna and that's where you start running into expensive issues. You couldn't just use wires to extend the antenna for instance, you'd have to use coax. And then that changes all sorts of things in the circuitry for the reader, it just becomes a bit of a nightmare to do properly.



  • I was thinking it would be hard to find an old phone that had NFC. I figured that one could use a USB reader and make sure the phone has OTG capabilities to host it. Then you have some distance with the USB. As far as placement and asthetics. There are a few kinds of readers. Some relatively slim, square ines, and even some USB flash drive sized ones. Could make for easy hidden placement like alongside a doorbell. I have been researching this on and off for years. And my goals have been like have been mentioned.

    But with ease of use, implementation into existing system, and especially cost of great importance. I have come up with a couple ideas. I like this one because the android device, even a tablet of any size could also double as an info device. With many inexpensive ones out there, and even people having extra ones. besides the above uses, imagine that it could also act as a front door camera with an inexpensive wifi or even bluetooth cam. Free if yo0u had just about any old android cellphone to secure outside.

    A crafth person might be able to put the camera, reader and doorbell in a case that looks like it belongs, and run the wiring through the bell wire hole. :idea:

    I wouldn't say I'm cheap. just not rich and thrifty. They say necessity is the mother of invention? It's stepfather is a lack of funds. :D

    lol, all sounds fair to me - I'll be interested to see how you go with it mate.



  • Any updates? I'm looking for a NFC solution for 5 doors.

    What about hooking a NFC reader to a Bluetooth chip and making a remote trigger for LOCKITRON?
