Hi all!

At least I found a nice (and cheap) european standard lock cylinder. Unfortunatelly it does not work with NTAG tags, only with Mifare 1K. I suppose the RECC610 (version without mechanical keys) does not work either. Product link.

@Pingi Hi. I think you should write about this problem on stackoverflow. Maybe Michael Roland spots your question and helps you, he is quite good in NFC things! Dont forget to come back with the solution to this forum ;)!

@korbin Technically it could replace it, but you have to ask your employer to approve it!

@MrStein Off course, I am interested in anything that has to do with NFC :)

As I see there are 15pcs available again on Elecrow. Are there any changes in the new batch?

Infineon press release is also out about the ring: http://www.infineon.com/cms/en/product/promopages/nfc-payment-ring/?intc=0120156

Some clarifications would be nice to know how to use the ring after we buy it?

Maybe try to add ACR1252U, ACR122T, SCM SCL3711 devices to the compatibility list

I have a business, but they dont sell only 1 cylinder and they also didnt told me the price.

Well, I contacted them (Hungary) but they only sell locks to special projects, they dont sell to "people from the street"...

Yes, i meant Keyduino :). Meantime I found an information on Keyduino forum that it will be available on Elecrow(.com) website. They are manufacturing the Keyduino I think.
