Important Points About USSD and Bharat QR Code – General Awareness

Unstructured Supplementary Service Data (USSD):

Unstructured Supplementary Service Data (USSD), sometimes referred to as “Quick Codes” or “Feature codes“, is a communications protocol used by GSM cellular telephones to communicate with the mobile network operator’s computers. USSD can be used for WAP browsing, prepaid callback service, mobile-money services, location-based content services, menu-based information services, and as part of configuring the phone on the network.

USSD messages are up to 182 alphanumeric characters long. Unlike Short Message Service (SMS) messages, USSD messages create a real-time connection during a USSD session. The connection remains open, allowing a two-way exchange of a sequence of data. This makes USSD more responsive than services that use SMS.

Uses

When a user sends a message to the phone company network, it is received by a computer dedicated to USSD. The computer’s response is sent back to the phone, generally in a basic format that can easily be seen on the phone display. Messages sent over USSD are not defined by any standardization body, so each network operator can implement whatever is most suitable for its customers.

USSD can be used to provide independent calling services such as a callback service (to reduce phone charges while roaming), enhance mobile marketing capabilities or interactive data services.

USSD is commonly used by prepaid GSM cellular phones to query the available balance. The vendor’s “check balance” application hides the details of the USSD protocol from the user. On some pay as you go networks, such as Tesco Mobile, once a user performs an action that costs money, the user sees a USSD message with his or her new balance. USSD can also be used to refill the balance on the user’s SIM card and to deliver one time passwords or PIN codes.

Some operators use USSD to provide access to real-time updates from social-networking websites like Facebook and Twitter. Wikipedia uses USSD to send articles to some feature phones.

USSD is sometimes used in conjunction with SMS. The user sends a request to the network via USSD, and the network replies with an acknowledgement of receipt:

“Thank you, your message is being processed. A message will be sent to your phone.”

Subsequently, one or more mobile terminated SMS messages communicate the status and/or results of the initial request. In such cases, SMS is used to “push” a reply or updates to the handset when the network is ready to send them. In contrast, USSD is used for command-and-control only.

Technical details

Most GSM phones have USSD capability. USSD is generally associated with real-time or instant messaging services. There is no store-and-forward capability, as is typical of other short-message protocols like SMS. In other words, an SMSC is not present in the processing path.

USSD Phase 1, as specified in GSM 02.90, only supports mobile-initiated (“pull”) operations. In the core network, the message is delivered over MAP, USSD Phase 2, as specified in GSM 03.90. After entering a USSD code on a GSM handset, the reply from the GSM operator is displayed within a few seconds.

Format

A typical USSD message starts with an asterisk (*) followed by digits that comprise commands or data. Groups of digits may be separated by additional asterisks. The message is terminated with a number sign (#).

USSD Mode

Mobile-initiated

  • USSD/ PULL or USSD/ P2P
  • when the user dials a code, e.g. *139# from a GSM mobile handset

Network-initiated

  • USSD/ PUSH or USSD/A2P
  • when the user receives a push message from the network; primarily used for promotional services

BharatQR:

BharatQR, developed by NPCI, Mastercard and Visa, is an integrated payment system in India. The system, which was launched in September 2016, facilitates users to transfer their money from one source to another. The money transferred through BharatQR is received directly in the user’s linked bank account. It provides a common interface for American Express, Visa, Mastercard, and RuPay cards. As opposed to other such systems, used by private companies and banks, BharatQR is interoperable with all the banks. Currently, BharatQR is supported on Android and iOS devices.

Overview

BharatQR was launched in September 2016 as per the directions set by the Reserve Bank of India with aim of facilitating India in transition to a less-cash society. The system helps in enabling digital payments to reduce the usage of card swiping machines for payment. A number of banks supported BharatQR, before the system was launched, and got ready to deploy it.

Although, BharatQR primarily works by scanning QR codes, it is not the only way to make payments. It allows users to pay through Aadhar number, UPI payment address or through account number and IFSC code, thus, minimizing the need to pay using debit and credit card which are, supposedly, less secure than BharatQR. The system, also, supports Dynamic QR code generation which eliminates the need of entering the amount for payment.

Usage

By early 2018, Delhi Metro Rail Corporation is planning to introduce BharatQR code enabled AFC gates at all the stations of the Airport Express Line allowing passengers to use the system while using the Line. Two entry points at Lal Qila metro station and two exit points at Jama Masjid metro station are set by DMRC providing commuters to enter and exit using QR codes.

Samsung Pay, which earlier in 2017, integrated Samsung Pay mobile wallet with Unified Payments Interface, integrated BharatQR to pay at merchants supporting UPI payment system.
