Hi....I am trying to connect a Rapsberry pi to parallax Propeller microcontroller. My intend is to use the propeller read comands from the pi and control motors and read sensors and relay the information back to the Pi on a mobile robot. I intend to add vision eventually using OpenCV or some other vision library so the Usb port cannot be used for communications. Any information regarding how to do the communications would be appreciated. Oh and one more thing my programming experiences are primarly C++ and Java with a little basic.

Dormakaba evolo locks work well at least when using a Mifare master card and whitelist mode.

+1 and use Mifare Desfire Ev2 so one can use it with different mastercards

I like Kwikset locks. Although one blogger writes that Schlage is good too. P.S. I think you should read, Richard knows what he is writing about. Good luck (Richard`s blog)

Hey guys I updated the Google Spreadsheet w/ what door locks work w/ the SLE77 or not so please refer to that :) https://docs.google.com/spreadsheets/d/1pA2B4Ck0NDgiT30hev4OjfqQgG5nBGMY1pcDApsLaGw/edit?ts=5787f16d#gid=0

Hi @johnyma22 does this one work with the payments ring ?

Confirmed working by johnyma22 in previous post. You would need to program your NFC ring tag ID onto the system before the door lock would recognise it. All NFC rings have two tags embedded which will be able to be used with Salto

Hi, I understand MIFARE cylinders and NTAG chips used in NFC rings share the same NFC frequency (13.56 MHz) and the same ISO/IEC 14443 standard. I don't understand the limitation, especially as NFC ring say in their FAQ: "All door locks with NFC (ISO14443) should work fine." So maybe the cylinder you bought is not ISO-14443 compliant?

Hi, If you are using RFID tag reader/ writer that is not working well and not happy with that I think that you should choose other company RFID tag that easy to work with NFC ring. Hence there are many companies that provide top quality RFID tag online. For more updates visit on RFID Loyalty tag.

Really, If you are trying to change your simple door lock and want use electronic digital lock, I will say. You should try once www.sato.sg of primesource.me. These companies are providing top quality digital locks for home and business.

No reply?

It may not necessarily work, because even if it uses the same ISO standard and frequency it really depends on how the door reads the storage. Here is a reference to an old post from 3 years ago for a similar situation you're facing: https://forum.nfcring.com/topic/76/samsung-shs-2920-does-not-work/16 In short, the door may read the M1 card but not NTAG203 that is used in the ring.

Hey @aus-gazza to register a ring you just add it as you do any normal device. No special cloning etc!

If you are really looking for a locksmith i suggest http://locksmithtoronto365.com/. He installed my Kwikset system. Its good and reliable small company. Now i`m looking forward to smart Samsung lock. I recommend not to install yourself expecially when the lock is pricy.

@johnyma22 right, my bad. Not thinking before typing. :p
