The app gives the option to make payments either via mobile number or UPI ID, completing the transaction in a simple two-step process. To make a payment, the user needs to enter the mobile number or UPI ID of the payee, the amount and the UPI PIN. Upon confirmation, the payment is completed and the user gets a notification.
Currently, the GSPay app is available in 12 Indian languages, including English, Hindi, Marathi, Odia, and Assamese, among others. The company recently partnered with Nokia (HMD Global) to enable GSPay on some Nokia feature phones.
