I thought tap to pay used a one time code? Or are you saying tap to pay uses the PAN + a one time code?

There are two different interfaces. One exposes the number + name + expiry over unencrypted ISO 14443 interface. Readable by any compatible reader (IE, every NFC enabled téléphone - https://www.apkmonk.com/app/com.github.devnied.emvnfccard/)

The EMV / payment interface is a different interface and fully encrypted.
