37Shares A curious new fintech platform called convertCASH claims it will pay for your monthly car and home instalments first without charging any interest. ADVERTISEMENT “It is interest-free, no borrowing with instant approval. We only require the users to have a credit card as security while using convertCASH’s ‘Pay for you First’ benefit. They can then pay back to the credit card up to 45 days later without any interest charge,” said convertCASH co-founder Jason Bak. Bak said this system will eliminate the need for car and/or homeowners to borrow money from friends or family to keep up with those monthly instalments. Once relevant details are filled in, convertCASH claims it will pay the instalment within one working day.
