Mobile payment start-up Square has received an investment from Visa. Financial terms of the deal have not been disclosed. However, a person familiar with the deal told Los Angeles Times that it was in the "single-digit millions". In connection with the investment, a Visa executive will join Square's advisory board. "Square's early success suggests that using Square and a mobile device, new types of merchants will now be able to accept payment and help grow their business via Visa's global network with the security, speed and reliability we provide," Visa's president, John Partridge, said in a written statement. Square closed a USD 27.5 million round of funding led by Sequoia Capital in January, giving the company a valuation of USD 240 million, up from USD 45 million in the previous round of funding.
