The Indian fintech ecosystem has seen a significant growth spurt over the past decade, driven by factors such as increased smartphone penetration, government initiatives, and rising digital literacy.

The India Stack, a collection of digital infrastructure and platforms, has been a key enabler of this growth. The India Stack is built on four pillars - Aadhaar, UPI, eKYC, and DigiLocker.

In this article, we will delve deeper into each of these pillars to understand their importance and impact on the Indian fintech ecosystem.

Pillar 1 - Aadhaar

Aadhaar is a unique identification number issued to every Indian resident. It is a biometric-based identification system that includes a person's demographic and biometric information.

Aadhaar has become an important component of the Indian fintech ecosystem, enabling digital identity verification, e-KYC, and other authentication services.

According to the Unique Identification Authority of India (UIDAI), over 1.2 billion Aadhaar cards have been issued as of March 2021.

The Supreme Court of India has also restricted the use of Aadhaar for certain services, citing concerns about privacy and data protection.
