Device fingerprinting is a technology that identifies a user’s device based on a combination of technical parameters. In simple terms, the system creates a unique digital profile of a device using dozens of characteristics.

These may include:

• operating system version
• browser type
• screen resolution
• device language
• IP address
• time zone
• processor and graphics chip characteristics
• network parameters

All these signals are combined into a unique device identifier. The key advantage of this technology is that it works invisibly in the background and does not require additional actions from the user during payment.

Starting in 2026, new RBI requirements focused on risk-based authentication are being introduced in India.

This means payment systems must dynamically evaluate the risk level of each transaction rather than relying solely on standard verification methods.

Companies that begin implementing such solutions early will be able to adapt more quickly to changing market requirements.

For Indian e-commerce, fraudulent orders and payment abuse remain major problems.

For example:

• creation of multiple fake accounts
• abuse of promo codes
• cash on delivery fraud
• repeated orders from the same device under different names

Device fingerprinting helps detect such schemes before payment confirmation. If the system identifies a suspicious device or repeated behavioral patterns, the transaction automatically receives a high-risk status.

As device analysis technologies evolve, attention to personal data protection is also increasing. In India, this has become especially relevant following the implementation of the Digital Personal Data Protection Act. Companies using device fingerprinting must inform users that technical device data is being collected for security and fraud prevention purposes. That is why businesses must not only implement security technologies but also maintain transparent data processing policies. Device fingerprinting is becoming one of the most important tools for securing digital payments in India in 2026. With rising fraud levels and stricter RBI requirements, businesses can no longer rely solely on OTP codes and traditional authentication methods. Modern security systems must analyze not only the user but also the device used for the transaction. This approach makes it possible to combine strong security, seamless payment experiences, and compliance with evolving market requirements.
