Can Someone Accidentally or Maliciously Tap My NFC Business Card?
This concern touches on both accidental reads and deliberate unwanted reads. Here is the reality.
Accidental Taps
For an accidental tap to happen, a phone would need to come within about 1 to 2 centimetres of your card. If your card is in your wallet, bag, or card holder, an accidental tap from a passing phone is essentially impossible. NFC requires deliberate, close contact.
Malicious Reads
Even a successful malicious read yields only the URL stored on the chip, which points to your publicly accessible Linktree or landing page containing only information you have chosen to make public.
Write-Protection
Tappio cards are write-protected after programming. Even if someone attempted to write new data to your chip, they cannot. The stored URL is locked.
The Practical Assessment
The security risk of NFC business cards is minimal. The chip stores a public URL. Physical proximity is required to read it. The card cannot be remotely read.
