Technical Differences: Static vs Dynamic QR Codes

What is a static QR code in UPI

A static QR code contains fixed payment details. Users scan it and manually enter the amount before completing payment.

It is commonly used by small merchants and individuals.

What is a dynamic QR code

Dynamic QR codes are generated for specific transactions and include details like amount and transaction ID. Users only need to scan and approve.

These are widely used in organized retail and online payments.

Key technical differences

Static QR = fixed data
Dynamic QR = transaction-specific data

This difference impacts usability and security.

Real-world usage scenarios

• Static QR: street vendors
• Dynamic QR: malls, e-commerce

Each serves a different purpose.

Advantages and limitations

Static QR is simple but requires manual input. Dynamic QR reduces errors but needs system integration.

Security implications

Dynamic QR reduces risk of incorrect payments, while static QR requires careful verification.

Choosing the right type

Depends on business size, transaction volume, and system capability.

UPI transactions are governed by NPCI guidelines.
