nfc reading

Looking for the simplest way to read data from an NFCV tag in B4i (and B4A) Looked on the forums and there's no clear solution Any help would be greatly appreciated Thanks

I have downloaded the file AdvancedNFC.zip from here https://www.b4x.com/android/forum/threads/nfc-reading-and-writing.64451/ I try to run it and I get an error on line 38. How can I solve this? Logger connected to: emulator-5554 --------- beginning of main --------- beginning of system ***...
