Can you remotely disable an NFC card?
Yes. You can effectively disable an NFC card by deactivating or removing the profile it points to. The chip still works and will try to open the URL, but if the profile is deactivated, the tapper sees a 'profile not found' page or is redirected away. The card becomes useless without physically altering the chip.
How profile deactivation works
Log into your platform dashboard and deactivate, pause, or delete the profile associated with the card. From that point, anyone who taps the card hits a dead endpoint — your platform shows a 'page not found' or a blank page. For company team accounts, admins can deactivate an employee's profile the moment they leave — no need to physically retrieve the card.
The difference between deactivation and deletion
Deactivation (pausing a profile) keeps your data intact and lets you reactivate later. Deletion removes the profile permanently. For employee offboarding, deactivation is typically safer — you can review or export the data before permanent deletion. Both effectively prevent the card from working.
What if a lost card is found and tapped?
If you've deactivated the profile, tapping the card does nothing useful. If the profile is still active, the finder sees your public profile — same as anyone else would.
Can you report an NFC card as stolen?
To your platform, yes — they can deactivate it. There's no broader reporting mechanism (unlike a stolen credit card) because NFC business cards don't enable financial fraud.
Is there a way to lock the chip so it truly can't be read?
Enclosing the card in an RFID-blocking sleeve physically blocks reads. But for business cards, simply deactivating the profile is usually sufficient.
