E-RUPI is a cashless digital payment system introduced by the Indian government. It uses QR codes or SMS strings to deliver vouchers to user's phones that can only be redeemed for a specific purpose, such as buying medicine. E-RUPI aims to help deliver services under government welfare schemes more efficiently by ensuring funds are used as intended without physical contact or the need for digital payment apps. Key benefits are that it keeps user details private, allows only intended purchases, and prevents misuse of funds. E-RUPI was launched on August 2, 2021 by the National Payments Corporation of India to promote cashless transactions for services like healthcare.
