What Is An mPIN Number?

The full form of a mPIN is a mobile personal identification number. It is important to understand that mPIN means a unique numeric 4 or 6-digit code for authentication and authorization in mobile banking and digital transactions. It plays a significant role in ensuring the security of financial transactions conducted through mobile devices.

Now, let us take an example of an mPIN number. To create and manage an mPIN, register with a bank or financial institution that offers digital banking services like a mobile money identifier. You will be asked to set up a personalised PIN during registration. This PIN acts as your mPIN.

The mPIN facilitates various banking services such as fund transfers, bill payments, and mobile wallet transactions. Whenever you initiate a transaction through your mobile device, you will be prompted to enter your mPIN to authenticate and authorise the transaction.

mPIN Meaning

Now you have a general understanding of what is the mPIN, let us discuss the meaning of the mPIN number. It is a 4 or 6-digit passcode you must enter whenever you wish to make a transaction. The mPIN is valuable because you do not have to enter IFSC (Indian Financial System Code) or other information each time you want to send or receive money.

You might have seen mPIN and UPI (unified payments interface) used in the same place many times, so now you might wonder what is UPI. The UPI is India’s leading digital payment platform. It does not have a minimum transfer limit, which enables consumers to use this payment mode daily. While this payment mode is still in its infancy, it has already made significant inroads into consumer mindset and behaviours. One does not think twice before whipping out a mobile phone and scanning a QR code or entering beneficiary details to make digital payments.

Without the need to memorise IFSC codes and bank details, UPI offers consumers a fairly straightforward way to make transactions at will. Now that you have an idea about what is UPI ID, let us talk about mPIN with examples.

How Can You Register Yourself on a UPI App?

To use UPI, you must begin by downloading a UPI-enabled app. As there are many apps to choose from, you must consider your usage patterns before selecting the right one for your needs.

When you download an app for the first time, you must register yourself on it. The registration details you must fill out are your name, virtual ID (or virtual payment address), password, and bank details. Depending on the app you downloaded, you can link multiple bank accounts if you need to.

Once the basics are taken care of, you must create an m-PIN. Like an ATM PIN, an mPIN is a 6-digit passcode you must enter whenever you wish to transact. The mPIN is highly valuable because you do not have to enter IFS codes or other information each time you want to send or receive money, which is why the mPIN proves to be a great means to confirm one’s identity. Without this pin, you cannot make transactions. This ensures that if your phone goes into the wrong hands, you will not find yourself staring at huge transactions and an empty bank account the next day.

Who Can Use UPI?

Anyone with a registered bank account can use UPI as and when they like. This mode of payment functions outside of banking hours, giving you great freedom when transferring funds. The payment mode does not have a minimum transfer limit, so you can use it to pay your local vendors and merchants, pay for transport, clear utility bills, make purchases online, and make any remittances you may require.

UPI is a form of payment introduced by the National Payments Corporation of India (NPCI) and was created with the facilitation of a digital economy in mind. This is why the payment types that this mode facilitates are so accessible.
