FAQs

Should I lock my tag after writing it? Only if you’re sure the content won’t change. Locked tags can’t be edited.
My iPhone won’t write the tag—why? Some iPhone models read but don’t write reliably through thick cases or metal; remove the case and try again, or move the tag away from metal.
Can I store my full contact card on the chip? You can, but a short branded URL to a profile/VCF is easier to update and more reliable across devices.
