how to write nfc NTAG215 cards and read it without an app on iphone

Question

I am interesting in writing an url to NTAG215 cards, so far I have download some apps for Ios tagwriter and NFC tools however once I try to read the card I have to open the app and read it, and my intention is to approach the phone and it will be able to pop up the window that let me open the link.

I have read and search quite a bit online about this but I am confused if this is something that needs to be develop using a sdk or its something the I have sort it out playing with the phone configuration.

any information will be much appreciated. JL

Answer 1

So iOS does support some background processing of URL's in the correct form.

See https://developer.apple.com/documentation/corenfc/adding_support_for_background_tag_reading

If you look at the NDEF spec https://github.com/haldean/ndef/blob/master/docs/NFCForum-TS-RTD_URI_1.0.pdf and look to only support URI Identifier Code 3 & 4 and possibly not 1 & 2

And from Apple's doc's

Note
Background tag reading doesn’t support custom URL schemes. Use universal links instead.

Definitely not URI Identifier Code 0 (custom URL)

And NXP Tagwriter App seems to default to "custom URL", so try writing the URL using the https:// or http:// from the drop down menu.
