American startup PayJoy makes it easier for people without a bank account or credit profile to purchase a smartphone on installment. The phones and loans are provided by third parties. What PayJoy provides is proprietary software that locks the phone if payments are not made on time, making the device unusable. Once the missed installments are paid, the phone is unlocked and can be used as normal. According to PayJoy, its technology can do more than just put smartphones in users' hands. Customers' payment histories are reported back to local credit bureaus, which serves to build up credit profiles. PayJoy aims to expand in emerging markets such as Asia, particularly in India and Indonesia. In most markets, PayJoy partners up with local mobile makers, distributors and lending institutions. The company then takes a cut from every loan originated using its technology, a business model that lowers costs as well as risks for PayJoy.
