Roadmap for Technology Upgrades in India's Payment Channels

Below is a roadmap framework for technological upgrades of payment platforms in India, incorporating industry trends, regulatory requirements (e.g., RBI guidelines) and localisation needs to plan key upgrades in a phased manner:

I. Short-term objectives (0-12 months)

Focus: Compliance Transformation & Infrastructure Optimisation

1. UPI 2.0+ Adaptation
   • Support mandates (auto debit), QR code dynamic generation
   • integrated (as in integrated circuit) e-NACH(automatic liquidation) and Bharat BillPay(Uniform bill payment)
2. security enhancement
   • PCI-DSS 4.0 Certification Readiness
   • AFA (Multi-Factor Authentication) Enhancements Required by RBI
3. performance enhancement
   • API response time optimised to <300ms
   • 99.9% SLA Guarantee

II. Medium-term objectives (1-3 years)

Focus: Intelligence & Eco-Extension

1. AI/ML application layer
   • AI risk control engine: real-time fraud detection (e.g., simulation of NPCI'sFraud Risk Management)
   • NLP-driven customer service automation (12 Indian languages supported)
2. Cross-border payment capacity
   Interconnection with systems such as PayNow Singapore
3. Offline payment programme
   SMS/USSD-based services for rural areas

III. Long-term evolution (3-5 years +)

Focus: Frontier Technology Integration & CBDC Integration

1. Central Bank Digital Currency (CBDC) Docking
   Reserved interface for digital rupee (e₹) settlement
2. Blockchain application pilot
   Smart Contract Settlement for Trade Finance Scenarios
   3.IoT Payment Scenarios
   Automated bill payment by car network, etc.

Key technology selection recommendations

Risk mitigation measures

• RBI Sandbox Testing Participation Programme
• NPCI co-development partnership established
• Tier-2/3 cities grey scale release strategy

Need to further refine the technical implementation of a particular phase or vertical? For example how to design India Stack compatible layered architecture.

Below is an in-depth extension of the solution for India's payment channel technology upgrades, with a module-by-module breakdown of the key implementation steps and recommendations for localised technology adaptations:

I. UPI eco-depth integration programme

1. Technology stack upgrade

• protocol layer
  • Adoption of NPCI publishedUPI Plug-in KitStandardised SDK
  • Support for RBI requirementsEMVCo QRcooperation with local communitiesBharat QRbiformat parsing
• Routing Optimisation
  • Deployment of intelligent routing algorithms (dynamic switching based on real-time success rates of PSP banks)
  • Priority use by Tier-3 citiesUPI LiteX(offline mode)

2. Feature Development

// UPI Mandate Auto-Renewal Example (Java Pseudo-Code)

class UPIMandate {

    void createRecurringPayment(String virtualId, double maxAmount) {

        NPCIAPI.validateAadhaarLink(virtualId); // Aadhaar validation

        mandateToken = generateRBICompliantToken(); // RBI standard tokenisation

        scheduler.scheduleCBDCsettlement(maxAmount); // CBDC settlement reserved interface

    }

}

II. Localisation of the risk control system

core component

Special Scenario Rules

• Anomaly detection at rural agency sites: Allow multiple account logins on the same device but limit the amount of cash top-up in a single day
• Religious holiday traffic control: Automatic expansion and enabling of alternate USSD channels during Diwali

III. Offline payment technology realisation path

1. Phase1-SMS/USSD base layer

   • TRAI-approved short code applications (e.g. *123#)
   • ASCII menu tree design (supports Hindi/Tamil etc.)

2. Phase2-IoT Enhancements

   # NFC tanker payment terminal example (Raspberry Pi implementation)
   
   def process_offline_payment().
   
       while no_internet.
   
           store_transaction_local(SQLite) # SQLite embedded database to store transaction records 
   
           sync_when_online() # Batch sync to NPCI node pool after CDMA network recovery 
   
   

3. Phase3 -- Satellite Backup Link (Tested in co-operation with ISRO)

IV. Regulatory Sandbox Participation Strategy

1. prioritisation

     B-->D[Singapore PayNow Interconnection].
   
     C-->E [Dialect Voice Bank Construction].
   
   

2. Compliance Testing Essentials

   • Prepaid Payment Instruments (PPI) licence compatibility verification
   • Data Localisation Audit (GDPR+Indian Personal Data Protection Act Double Check)

Do you need to focus on developing an engineering implementation programme for a specific technology? Example:

1. A specific implementation of Aadhaar hash desensitisation in the KYC process, or
