The move is an important opportunity for China UnionPay to expand its services in South America, the company said.

In September 2010, the company reached agreements with Redcard and Itau Unibanco, Brazil's largest commercial bank, to expand the acceptance of UnionPay cards by Brazilian merchants and ATMs in Brazil.

According to the agreements, Itau Unibanco will gradually add UnionPay card services to its 23,000 ATMs. A total of 130,000 Brazilian merchants using the Redcard POS system will also be able to accept UnionPay cards.
