Commerce, Secure and Mobile

"The mobile wallet will change the concept of money as we have understood it for years.” – Sam Pitroda

C-SAM envisions a world where every transaction, from making a mortgage payment to buying groceries, from paying a cabby to buying a movie ticket, from paying for parking to buying goods off vending machines, from sending personal health information to getting a diagnostic test-kit, and from filing an expense report to voting for representatives in public office, is done by clicking a few buttons on your mobile phones.

C-SAM has been tirelessly pursuing this vision for nearly 20 years. C-SAM pioneered the concept of the Digital Wallet in the early 90’s, recognizing very early that to deliver a true leather wallet metaphor on mobile phones it was imperative that existing providers come together on a common infrastructure platform, leveraging the advantages of the Internet and mobility, but yet maintaining their existing branding and risk management practices.

Essential to C-SAM’s vision are the underlying needs of consumers – an easy to use interface, ability to securely transact in the virtual and real world, a wide range of personalized applications, and the ability to get various profile driven value added services based on static preferences and dynamic behavior.

In 2013, C-SAM was sold to MasterCard.
