Very safe. Your actual credit card number is not used in the transaction, it generates a one time unique one each time it is used. SO very safe.
Correct, it's called a token. The signal emitted by the contactless chip in the card is readable and can be intercepted with a nearby scanner, but the card is not transmitting your real credit card number, it sends another number called a token that gets translated into your card number when it's received by the bank. So any info crooks steal using this method is worthless. Like intercepting an encrypted transmission, by the time the crooks decode it the token is no longer valid.
