Indian mobile-based payment solutions provider Ezetap Mobile Solutions Pvt. Ltd. has received undisclosed amount in investment from credit card giant American Express (Amex) in exchange for a minority stake.

Bangalore-based Ezetap said that it would utilize the funds invested by Amex to add services like loyalty points and rewards for consumers.

Speaking about the deal, Ezetap co-founder & CEO Abhijit Bose said, "This investment will allow us to turn on additional value added services such as loyalty and rewards that will delight users and change the entire payment experience for end consumers."

A few weeks back, the Indian company had bagged $8 million in a Series B round led by Helion Venture Partners. The list of other investors included Berggruen Holdings and Social+Capital Partnership.

Sanjay Rishi, president of American Express (South Asia), pointed out that the mobile point of sales solutions would play a crucial role in further enabling commerce by delivering a smart as well as convenient way for small businesses to receive consumer payments.

American Express Ventures, a subsidiary of American Express, last month invested nearly $4.5 million in consumer engagement firm Capillary Technologies.

Ezetap, which turns a merchant's mobile device into a smart point of sale capable of reading all cards and make financial transactions, was co-founded by Abhijit Bose (CEO) and Bhakta Keshavachar (CTO) in 2011.
