There's a (relatively low) transaction limit for contactless payments without additional verification. So, to buy a TV, you still need to enter a PIN. Newer payment terminals can support device-based customer verification for contactless transactions, called CDCVM. The transaction limit doesn't apply if CDCVM is used. This is the mechanism used by Apple Pay, where you verify your identity using your fingerprint via Touch ID.
