iPhone will not write, or the data does not fit

iPhone will not write

• iPhones are built mainly to read NFC. First-time writing often fails on them.
• Use any Android phone with NFC for the first write. After that the card reads fine on iPhone.
• On iPhone, NFC Tools needs iPhone XS or newer.

Data does not fit

• The chip memory is small. Long links and large contact records may not fit.
• Use a shorter link, or shorten it with a link shortener first.
• Choose a smaller record type, for example a link instead of a full contact.
