An NFC business card has a tiny chip inside. When someone holds their phone near it, the phone reads a web address from the chip and opens your profile — no app, no pairing, no typing. The whole thing takes about a second.
NFC stands for Near-Field Communication, the same short-range technology your phone uses for contactless payment. The chip is passive: it has no battery and does nothing until a phone comes within a couple of centimetres and powers it for that instant.
The key idea: the chip does not store your phone number or email. It stores a short web address that points to your online profile. That is what makes the card updatable for life — you change the profile, and the same address shows the new details. The object carries an address, never the data.
iPhone XR and newer read a tap automatically. Most Android phones from the last few years do too — NFC may need to be enabled once in settings. Older phones fall back to the QR code every card also carries.

The TapAdd way: pick your object — the Prime metal or PVC card, the Flex silicone band, the Pulse phone sticker, the Clip keyring or the Totem counter stand — and one tap opens your TapAdd profile, updatable for life.
No. The chip is passive and draws the tiny power it needs from the phone that taps it. Nothing to charge, nothing to break.
The tap works offline, but opening the profile needs a connection, like any web page.
