UPI Circle Explained: Delegated Payments for Families & Secondary Users

While India’s UPI ecosystem processes billions of payments monthly, a significant segment of the population remains digitally excluded: dependents, young students, elderly parents, and domestic helpers who either do not hold independent bank accounts, do not have active debit cards to set up a UPI PIN, or lack digital financial confidence.

Historically, families solved this by handing over physical cash for daily grocery runs or sharing primary phone screens.

To solve this demographic challenge safely, the National Payments Corporation of India (NPCI) launched UPI Circle (Delegated Payments).

Here is an analysis of how UPI Circle works, the two delegation models, and how Indian retail and e-commerce merchants benefit from expanded family purchasing power.

What is UPI Circle and Why Was It Created?

UPI Circle transforms a single bank account into a shared family payment hub:

The Traditional Family Payment Friction:
College student needs books ──► Calls parent ──► Parent sends manual transfer
Elderly parent at pharmacy  ──► Cannot remember UPI PIN ──► Forced to carry cash

The UPI Circle Solution:
[Primary Account Holder (Parent)]
               │
               ▼ (Delegates Monthly Allowance via App)
[Secondary User (Child / Parent / Assistant)]
  ├── Has their own smartphone and UPI app (GPay / PhonePe / BHIM)
  ├── Has ZERO bank account linked
  └── Scans any merchant QR to pay within authorized limits!

Secondary users can install Google Pay, PhonePe, or BHIM on their own smartphones and scan merchant QR codes without needing their own bank account or debit card.

Two Delegation Models: Spend With Limits vs. Approve Each Pay

NPCI designed two distinct operational modes to suit different family relationships:

┌──────────────────────────────────────────────────────────────────┐
│                   UPI Circle Delegation Models                   │
├──────────────────────────────────────────────────────────────────┤
│                                                                  │
│  MODEL 1: Full Delegation ("Spend With Limits")                  │
│  • Primary sets a monthly allowance (e.g., ₹5,000 / month).       │
│  • Secondary scans merchant QR and pays autonomously.            │
│  • Secondary uses their own device passcode or biometric.        │
│  • Ideal for college students, spouses, and daily groceries.    │
│                                                                  │
│  MODEL 2: Partial Delegation ("Approve Each Payment")             │
│  • Secondary initiates payment by scanning merchant QR.          │
│  • Push notification sent to Primary user's phone.               │
│  • Primary reviews merchant name and enters UPI PIN to approve.  │
│  • Ideal for high-ticket online shopping or younger teens.       │
│                                                                  │

How Merchants Benefit from Delegated Family Purchasing

For retail store cashiers, school canteens, bookshops, and e-commerce websites, UPI Circle unlocks a massive new demographic of digital shoppers:

1. Higher Retail Counter Throughput: Teenagers and college students who previously had to pay with physical paper cash (slowing down queues with change issues) can now scan merchant QRs instantly.
2. Zero Merchant Integration Changes: Because UPI Circle resolves delegated authorizations within the NPCI switch before communicating with the merchant’s acquiring bank, any standard merchant QR generated by VyaparGateway accepts UPI Circle payments with zero code modifications.
3. Guaranteed 0% MDR Settlements: Payments originating from UPI Circle draw from the primary user’s bank account, settling into the merchant’s current account as standard 0% MDR debit UPI.

The Engineering Behind Delegated Authorization Tokens

Under the hood, UPI Circle leverages cryptographic delegated authorization tokens managed by the NPCI switch:
