Who started UPI?

National Payments Corporation of India (NPCI) launched the UPI program in collaboration with the Reserve Bank of India and the Indian Banks Association (IBA).
The organisation called NPCI, which runs the RuPay payment infrastructure, operates similarly to MasterCard and Visa. It makes it possible for different banks to link and transfer money.
The NPCI has another project called Immediate Payments Service (IMPS). The UPI facility is currently viewed as an upgraded version of the IMPS facility.

What are PIN and UPI ID?

A bank account can be identified by its UPI ID in order to transfer and receive money. To authorise a money transfer using UPI, a 4-digit personal identification number known as the UPI PIN must be entered. The account holder has the option of selecting this PIN.

What exactly is UPI 2.0?

A new and future version of the UPI payment system, called UPI 2.0, has enhanced capabilities and advantages. The service is promoted as being more comprehensive, secure, and having an easier authentication process.

Future Functions of UPI 2.0

UPI 2.0 promises to be a more effective tool than UPI, despite the fact that it has many more functions. The following are some of the new features that UPI 2.0 will offer:
  • Paying bills
To send money to someone who has a bank account, customers can currently use the UPI system. The electricity bill payment option will, however, be added with UPI 2.0. With the help of this software, you may pay any time and anywhere for bills such as power, phone, insurance, mobile, credit card, and even EMI collection. Two banks are reportedly planning to offer the feature very soon, according to recent sources. Bharat Bill Payment System will be integrated with UPI to make bill payments easier.
  • Pre – Approved Transaction:

Through the addition of the pre-authorized transaction capability, UPI 2.0 solves the issue of forgetting about overdue bill payments. Regular bill payments can be made stress-free by authorising billers to automatically deduct the required amount from the user’s account prior to the bill due date. The number of automated payments can also be limited with the choice of the maximum amount restriction and pertinent date. EMIs will function with pre-authorized transactions as well.

  • Biometric verification

With the integration of fingerprint mapping technology and iris scanner in UPI 2.0, UPI-based payments are expected to become more secure. The Aadhar service will help to establish the option for biometric payment authentication. Since UIDAI has already gathered the biometric information for the majority of Indian people, using that database to confirm a user’s identity is possible. Smartphones with fingerprint scanners and high-quality cameras for iris picture capturing have rendered the less secure MPIN obsolete.

  • Verify the transaction’s speed:

Velocity Check, which is already used by some banks in India to provide better security, is being added to UPI 2.0 to ensure that fraudulent transactions can be detected and hopefully They can be prevented from being completed. Adding this feature to UPI 2.0 will significantly increase its reliability. Any suspicious transaction can be reported to the bank and the customer through the UPI app.

  • Error Correction:

The current UPI app displays an error if your cell number is connected to other people’s bank accounts, such as those of your family members.The phone number must be particular to a person in order for UPI to function. UPI 2.0 is trying to resolve this issue.

  • Planned Payment:

The UPI payment system does not currently offer the ability to schedule payments. However, UPI 2.0 will contain this function, giving the existing system the much-needed flexibility.

  • Payments Based on Aadhaar:

Aadhaar numbers would be used for payments starting with UPI 2.0.An Aadhaar number is more unique to a single person than a mobile number, which can have belonged to multiple people before you. Furthermore, a handful of banks have started linking accounts to account users’ Aadhar numbers, making it easier to execute transactions straight from bank accounts.

UPI Security

Transactions using UPI employ an extremely secure encryption format that is difficult to mess with. The IMPS network of NPCI now processes daily transactions totaling about Rs. 8,000 crore. With the advent of UPI technology, this was anticipated to rise. This also checks every transaction and uses two-factor authentication, similar to an OTP.
