(Reuters) - Visa Inc V.N beat analysts' estimates for quarterly earnings on Tuesday, as a robust economy encouraged customers to spend more and boosted fees for the world's largest payment processor.

Total payments volume rose 8.7% to $2.23 trillion, on a constant dollar basis, with the United States - its largest market - accounting for about 8.8% of the total.

Payments volume represents the dollar amount of purchases made with cards carrying Visa’s branding.

The number of transactions processed rose 11.7% to $35.43 billion.

Net income rose to $3.10 billion, or $1.37 per Class A share, in the quarter ended June 30 from $2.33 billion, or $1 per Class A share, a year earlier. (bit.ly/32LPG4m)
