(Reuters) - Visa Inc V.N on Friday said here Mary Kay Bowman will join as head of the business that is tasked to attract more customers to use the world's largest payments network.

Bowman joins from Square Inc SQ.N, where she was head of payments. Her departure is the second high-profile exit from the payments processor following the departure of its Chief Financial Officer Sarah Friar in December last year.

At Visa, Bowman will head the designing, development and delivery of new services, the company said.

Bowman's resume includes stints at Amazon.com Inc AMZN.O, where she was a director of global payments.

Payments processing companies such as Visa and Mastercard MA.N have been facing headwinds from digital payments companies, like Square and PayPal Holdings Inc PYPL.O which have blossomed in the midst of a fintech boom in the U.S.

Square, which is led by Twitter TWTR.N CEO Jack Dorsey, has been one of the top companies in the fintech arena that have been giving bigger payment processors a run for their money and is re-orienting itself to become more small merchant-friendly.
