What does UPI mean in texting?

In the context of texting and digital communication, UPI stands for Unified Payments Interface. It is a real-time instant payment system developed by the National Payments Corporation of India (NPCI) that allows users to transfer money between bank accounts as easily as sending a text message. Key features include:

• Instant money transfers available 24/7, including holidays.
• Use of a unique UPI ID or mobile number instead of bank account details.
• Secure transactions requiring a personal UPI PIN for authentication.
• Interoperability, allowing transfers across different banks through a single interface.
