ChangeJar designs mobile payment solutions that keep you in charge of your own money. ChangeJar is driving retail cash payments by making them mobile: as fast and convenient as credit or debit – but without the transaction fees. With the ChangeJar app on their phone, consumers can accumulate the value of change from physical cash transactions and then use it for mobile payment, tipping, and social giving. ChangeJar was founded in 2014 and is headquartered in Ottawa, Canada.
