Can a contactless payment go through twice?
Can a contactless payment go through twice? You can't pay accidentally—your contactless card or payment-enabled mobile/wearable device must be within 2 inches of the terminal for the transaction to take place. And you won't be billed twice, even if you accidentally tap twice.
What are the rules on contactless payments?
Because no signature or PIN verification is typically required, contactless purchases are often limited to a maximum amount per transaction, known as a Cardholder Verification Limit (CVM limit). Limits vary between banks.
