Beginning this month, four of the largest credit card networks in the United States no longer require signatures to complete transactions — a move driven by evolving security and technology.
American Express, Discover and Mastercard gave merchants the option to stop requesting handwritten authentication for credit and debit card transactions April 13, while Visa implemented the policy the following day.
Terms for the change will vary. American Express eliminated the requirement for all its cards globally, while Visa lifted the requirement only in the United States and Canada for payment systems that read chip cards.
Mastercard ended the requirement exclusively in North America, while Discover offers the choice in the United States, Canada, Mexico and Caribbean nations.
