Getty Images By Lisa Gerstner, Contributing Editor March 7, 2019From Kiplinger’s Personal Finance For years, Apple Pay and other mobile wallets have offered customers the ability to “tap to pay” at the register. Now, U.S. credit- and debit-card issuers are hopping on the bandwagon. Contactless payments are typically speedier than transactions in which you insert a card into a chip reader.

A contactless card transfers unique, encrypted data when you tap to pay—just as it does when you insert it into a chip reader—so that thieves can’t glean enough useful information in a breach to create counterfeit cards. Fraudsters could use a skimming device to steal data from your card by coming in close proximity to it. But that’s not a valid concern because crooks still can’t gather enough viable data to make counterfeit cards, says Randy Vanderhoof, director of the U.S. Payments Forum.
