iOS Question Reading NFCV (ISO15693) Tags

[jackdev65]

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

Only Ndef tags are supported: https://www.b4x.com/android/forum/threads/nfc-reading-ndef-tags.84784/#content

I have a client that needs support for NFCV, so I am quite desperate for a solution, there are apps out there that can scan them on iOS from my testing.
What roughly would I need to do to implement this in B4i, even if it's theoretical?

Example NFCV

This thread seems to have achieved it for B4A some years ago

Thanks

Support for latest NFC-v ISO15693 tags

Hello Does the current b4i version and iNFC v1.1 support read/write RAW data bytes from nfcv (iso-15693) tags? ( introduced in the latest ios version if i'm not mistaken) I've been working with these tags, only on android, for a few years now, and i'd really like to convert my app to ios...

That thread mentions NFCEx code, where can this be found?
Also is this NFCEx different from the built-in NFC library, or are they both required?

Thanks

Thank you, are you able to summarise what exactly NFCEx is and tie it into my second question so I'm on the same page, is it a separate NFC library to the built in one or does it rely on the built in one

Thanks

NFCEx is a class that adds some features to the iNFC library, however it won't be simple to support non-NDEF tags. You will need good understanding of Objective C and native iOS.

some nfcv tags are factory-formatted to ndef. some can be formatted to ndef. otherwise, even if you could read the tags using transceive(), the actual data could well be stored in a proprietary format. is that how your client is using these tags?
