Can an NFC business card be hacked?
There's no login or software on the chip to break into.
An NFC business card chip doesn't run software, hold a password, or accept commands — it stores a link and responds to a read request from a few centimeters away. There's no server, app session, or account sitting on the physical card for anyone to break into.
The only thing 'hacking' could mean here is someone gaining access to your app.smartcards.ng account, which is protected the same way any online account is — by your login credentials. Use a strong password and don't share your license key, and that risk is the same as it is for any online account.
Compare that to a phone number or email printed on paper: once it's out there, there's no way to update or revoke it. Your SmartCard profile can be changed or shut off any time from your account.
Nothing to hack remotely
The chip only stores a link — there's no login, wallet, or session on the card itself for anyone to break into.
