What they get when they tap.
The same thing they would get if you texted the link. WhatsApp, Instagram, your number, a Google review page — whatever you set. They do not get a login to TAPSYNC. They do not install an app.
Straight answer
Are NFC cards safe?
Yes, if you know what the chip holds. A TAPSYNC Digital, Social or Review card stores a TAPSYNC link — not your debit card, not your password. They tap. A public page opens. You decide what is on that page.
What if I lose the card?
Anyone who finds it can open the same public page. Log in at tapsync.in and change the destination, or write to hello@tapsync.in. The lost plastic is just plastic. The profile stays yours. Order another card if you still want one in the wallet.
Smart Wi-Fi is a different object.
The face holds a WIFI: join — that is how guests get online without spelling the password. They do not see you type it. Keep a guest network if you do not want them on the home LAN. Change the network from the QR on the back. How both sides work.
Wallet and debit cards.
TAPSYNC is wallet-size. Do not stack it tight against a contactless debit card if taps feel flaky — give it its own slot. The card has no battery. It does not charge. It does not run when nobody is holding a phone to it.
