Features

Same NFC card on the surface — a completely different service behind it.

Pre-linked before it ships

Chip written, account linked — you just fill in and publish

Push, LINE and Email alerts with GPS location the moment it's tapped

Bounced emails and unlinked LINE accounts are flagged instantly — your safety net never dies quietly

Bilingual public page, local emergency numbers by the finder's country, timezone-aware alerts

The one who fills the card needn't be the one who carries it

Disable the page instantly — good-faith finders can still request access

One message with location and status reaches the family instantly

Guardian, gifting, business and custom links in one account — buying NFC here adds quota

They're great — for a different problem. Full comparison here.
