Android Question NFC - phone behave as rfid tag

[Drago Bratko]

I'm trying to do simple app which would on click of a button transmit data as would rfid tag do.
So, phone should act as rfid tag which is put over standard rfid reader (in my case connected to computer). Ideal would be that I can send serial number (on my own) and data.

I was playing with NFC example, but can't make it work in such scenario. Maybe I'm doing something wrong ...

Any suggestion would be helpful.

I have found old Erel's answer from May 14, 2019 :

Android does support it: https://developer.android.com/guide/topics/connectivity/nfc/hce.html
However it is not a simple feature to use. Currently there is no library that wraps this feature.

Has something changed in between?

 

[Erel]

I don't think so. Sorry.

Thank you for your feedback.

Which way(s) do you see that this would be possible to do with elegancy of b4x tools?
Is there something out there what could be wraped? Or some other way?
I ask because on one side I don't know how to do it ... but if I would know options, maybe I (or we as comunity) would found a way.

It can, Google Pay and Googel Wallet do it as well as London Transports' Oyster card and other payment schemes. However I don't think you will find a way with B4A without trying to do it yourself as it looks a bit complicated

Yes, I have run to that link also, and for me that's something what I don't know how to implement on my own.

It looks that I'm not the only one which would need that feature ... but question is, is there enough of us needing that ... I hope yes.

Anyone interested to make that library? I would be first to buy it.
