UPI QR Code-CBDC Interoperability: Simplifying Digital Transactions
Interoperability
- UPI (Unified Payments Interface) QR code interoperability with the digital rupee (Central Bank Digital Currency or CBDC) means that UPI QR codes can seamlessly work with CBDC apps.
- Initially, users of the e₹ (retail digital rupee) had to scan a specific QR code for transactions.
- Now, with the interoperability in place, payments can be made using a single QR code.
How e₹ Works:
- The e₹ is stored in a digital wallet, which is linked to the user’s existing savings bank account.
- UPI, on the other hand, is directly linked to the user’s bank account.
Benefits for Customers and Merchants:
- The interoperability of UPI and CBDC streamlines transactions for both customers and merchants, eliminating the need to switch between multiple digital platforms.
- Digital rupee users can make payments for everyday essentials like groceries and medicines by scanning any UPI QR code at any merchant outlet.
- Merchants do not need a separate QR code to accept digital rupee payments; they can use their existing QR code.
- If the merchant has a CBDC account, the payment will be settled in the CBDC wallet.
- If the merchant lacks a CBDC account, customers have the option to make payments using UPI.
- In essence, UPI QR code-CBDC interoperability simplifies digital transactions, making it convenient for users of the digital rupee and ensuring that merchants can accept payments seamlessly without the need for additional infrastructure.
Understanding QR Codes:
- A Quick Response (QR) code is a pattern of black squares arranged on a white background. It can be scanned and read by imaging devices like cameras.
- These codes contain information related to the item or application they are linked to.
- QR codes provide a contactless payment channel, enabling businesses to receive payments directly into their bank accounts.
The Role of Interoperability in CBDC Adoption:
- Interoperability between UPI (Unified Payments Interface) and CBDC (Central Bank Digital Currency) is expected to boost the adoption of digital rupee.
- UPI is currently a widely utilized payment method with more than 70 mobile apps and over 50 million merchants accepting UPI payments.
- As of July, there were 1.3 million customers and 0.3 million merchants using the retail digital rupee (e₹-R).
- Daily e₹-R transactions in July ranged from 5,000 to 10,000.
- The seamless integration of CBDC with UPI will enhance the acceptance and usage of digital currencies in everyday transactions.
What is E-rupee?
- E-rupee is the same as a fiat currency and is exchangeable one-to-one with the fiat currency.
- Only its form is different. It can be accepted as a medium of payment, legal tender and a safe store of value.
- The digital rupee would appear as liability on a central bank’s balance sheet.
What are the types of e-rupee?
Based on the usage and the functions performed by the digital rupee and considering the different levels of accessibility, CBDC can be demarcated into two broad categories —
Retail CBDC
- It is an electronic version of cash primarily meant for retail transactions.
- It will be potentially available for use by all — private sector, non-financial consumers and businesses — and can provide access to safe money for payment and settlement as it is a direct liability of the central bank.
- However, the RBI has not explained how e-rupee can be used in merchant transactions in the retail trade.
Wholesale CBDC
- It is designed for restricted access to select financial institutions.
- It has the potential to transform the settlement systems for financial transactions undertaken by banks in the government securities (G-Sec) segment, inter-bank market and capital market more efficiently and securely in terms of operational costs, use of collateral and liquidity management.
What are the forms of CBDC?
The central bank says e-rupee, or CBDC, can be structured as
Token-based CBDC
- It would be a bearer instrument like banknotes, meaning whosoever holds the tokens at a given point in time would be presumed to own them.
- In a token-based CBDC, the person receiving a token will verify that his ownership of the token is genuine.
- A token-based CBDC is viewed as a preferred mode for CBDC-R as it would be closer to physical cash.
Account-based system
- It would require maintenance of record of balances and transactions of all holders of the CBDC and indicate the ownership of the monetary balances.
- In this case, an intermediary will verify the identity of an account holder.
- This system can be considered for CBDC-W.
What’s the model for issuance?
There are two models for issuance and management of CBDCs under the RBI’s consideration —
Direct model (single tier model)
- The central bank will be responsible for managing all aspects of the digital rupee system such as issuance, account-keeping and transaction verification.
Indirect model (two-tier model).
- An indirect model would be one where the central bank and other intermediaries (banks and any other service providers), each play their respective role.
- In this model, the central bank will issue CBDC to consumers indirectly through intermediaries and any claim by consumers will be managed by the intermediary.
What are the advantages of e-rupee?
- Reduction in operational costs involved in physical cash management,
- It will foster financial inclusion,
- It will bring resilience, efficiency and innovation in the payments system.
- It will add efficiency to the settlement system and boost innovation in cross-border payments space and provide the public with uses that any private virtual currencies can provide, without the associated risks.

Laws Governing Forests of the Northeast
Context:
On August 22, the Mizoram Assembly passed a resolution unanimously to oppose the Forest (Conservation) Amendment Act, 2023. This amendment permits the use of forest land for various projects within 100 km of India’s international borders without the need for forest clearance. The Mizoram Assembly’s move is aimed at safeguarding the rights and interests of its people. This amendment affects most of India’s Northeast. Nagaland is expected to follow suit in the coming week, facing similar demands to oppose the amendment. Notably, even states like Tripura, Mizoram, and Sikkim, governed by the Bharatiya Janata Party (BJP) or its allies, have expressed their opposition to the 100-km exemption clause.

Is FCA Applicable to the Northeast?
Constitutional Protections for Northeast States
- Article 371A for Nagaland and 371G for Mizoram offer constitutional protections.
- Laws enacted by Parliament affecting customary law, land, and resources need Assembly approval.
Application of FCA in Nagaland
- In 1986, Nagaland extended FCA to government forests and certain wildlife sanctuaries.
- Controversy arose over the applicability of FCA.
- Home Ministry initially said FCA doesn’t apply as per land resources.
- Environment Ministry later contradicted this, leading to no FCA clearances since 1980.
Application of FCA in Mizoram
- Mizoram gained statehood in 1986 with Article 371G extension, including FCA.
- Autonomous District Councils’ powers don’t extend to reserved forests.
- FCA covers 84.53% of notified forests, with some receiving FCA clearance.
FCA in the Rest of Northeast
- FCA applies in Meghalaya, Tripura, Sixth Schedule Areas in these states, and Arunachal Pradesh, Sikkim, Manipur.
- Arunachal Pradesh leads in FCA clearances, followed by Tripura, Assam, Manipur, Sikkim, and Meghalaya.
Understanding RFA and Its Impact
FCA and Forest Diversions
- Over 1 million hectares of forest diverted under FCA since 1980.
- FCA’s aim: Forest deforestation as per Indian Forest Act 1927.
Expansion of “Forest Land”
- Supreme Court, in 1996 Godavarman case, broadened “forest land” in FCA.
- Now includes any area marked as forest, regardless of ownership.
- Includes unclassed forests, recorded but not notified.
Recorded Forest Area (RFA) in Northeast
- Over half of Northeast is RFA.
- RFA has 53% unclassed forests, governed by local customary laws.

What is Human Immunodeficiency Virus (HIV)?
- HIV stands for human immunodeficiency virus.
- It harms your immune system by destroying a type of white blood cell that helps your body fight infection.
- This puts you at risk for serious infections and certain cancers.
AIDS
- AIDS stands for acquired immunodeficiency syndrome.
- It is the final stage of infection with HIV.
- It happens when the body’s immune system is badly damaged because of the virus. Not everyone with HIV develops AIDS.
HIV can spread in different ways:
- Through unprotected sex with a person with HIV. This is the most common way that it spreads.
- By sharing drug needles
- Through contact with the blood of a person with HIV
- From mother to baby during pregnancy, childbirth, or breastfeeding
Symptoms of HIV/AIDS
- Fever
- Chills
- Rash
- Night sweats
- Muscle aches
- Sore throat
- Fatigue
- Swollen lymph nodes
- Mouth ulcers
What are the current treatments for HIV?
- Although there are no cures for the infection at present, the disease can be managed using antiretroviral therapy.
- These medicines suppress the replication of the virus within the body, allowing the number of CD4 immune cells to bounce back.
- Although earlier the drugs were given only to those with low CD4 count under the government’s programme, now the programme supports anyone who has been diagnosed with HIV.
- The drugs have to be taken for life because the virus continues to persist in reservoirs across the body. If the drugs are stopped, the virus can again start replicating and spreading.
- When the viral levels are low, the likelihood of a person transmitting the infection is also low.
- If left untreated, the virus destroys a person’s immune system and they are said to be in the Acquired Immunodeficiency Syndrome stage (AIDS) where they get several opportunistic infections that may result in death.
- Although there is no vaccine for HIV, there are Pre-exposure prophylaxis (or PrEP) medicines that can be taken by people at high risk of contracting the infection. PrEP reduces the risk of getting HIV from sex by about 99 per cent.
Key Highlights of the Global Fund’s Deal
- The deal will reduce the cost of the advanced HIV drug Tenofovir disoproxil, Lamivudine and Dolutegravir (TLD) by 25%.
- This reduction will enable the provision of TLD for less than USD 45 per person per year.
- The lower pricing of TLD will facilitate the expansion of treatment programs, potentially reaching an additional 19 million people living with HIV in resource-limited areas.
About the Global Fund:
- The Global Fund is a global initiative established in 2002 to combat HIV, tuberculosis (TB), and malaria and promote a healthier, more equitable future worldwide.
- It operates on a three-year funding cycle, providing greater predictability in the fight against these diseases.
- Funding is contributed by governments, the private sector, and non-governmental organizations to support its mission.
Global Fund’s Mission:
- Raise and invest USD 4 billion annually to combat the deadliest infectious diseases, address the underlying injustices, and strengthen healthcare systems in over 100 countries.
Global Fund Strategy (2023-2028):
- The primary objective of the strategy is to eliminate AIDS, tuberculosis, and malaria, with a specific emphasis on making transformative investments and harnessing innovations to accelerate progress in reducing new infections.
Tenofovir disoproxil, Lamivudine, and Dolutegravir (TLD)
- A TLD, or Tablet TLD, stands for a fixed-dose combination of three antiretroviral drugs used in the treatment of HIV.
- These three drugs are Tenofovir, Lamivudine, and Dolutegravir.
- Tablet TLD is considered the primary treatment for over 85% of HIV cases.
- It is highly recommended by the World Health Organization as the preferred first-line HIV treatment for both adults and adolescents.
- This combination of antiretroviral drugs is known for its ability to rapidly suppress the HIV virus, causing fewer side effects and being convenient to administer.
