How do contactless card readers work?
How do contactless card readers work? A contactless credit card uses RFID technology to enable you to hover or tap a card over a card terminal as a means of conducting a transaction. The card emits short-range electromagnetic waves containing your credit card information to be captured by the point-of-sale system and processed to complete the transaction.
What happens if someone used my contactless card?
What happens if someone else uses my contactless card? As with unauthorized charges to any other cards, the bank will be liable, not you. If you suspect any unauthorized transactions, report them immediately to your card issuer.
