'''India Stack''' is a marketing term coined by [[ISPIRT|iSPIRT]] (Indian Software Product Industry Round Table) to brand a collection of government-operated digital infrastructure systems in [[India]] as a unified platform.<ref name="indiastack-watch">{{cite web|url=https://indiastack.in/|title=India Stack Watch|access-date=7 January 2025}}</ref> The term encompasses identity verification ([[Aadhaar]]), payments ([[Unified Payments Interface|UPI]]), document storage ([[DigiLocker]]), and data sharing layers--each governed by separate government bodies with distinct legal frameworks.

The systems have achieved significant scale, with UPI processing over 10{{nbsp}}billion monthly transactions and Aadhaar covering 1.4{{nbsp}}billion residents. However, the platform has faced sustained criticism regarding welfare exclusion linked to biometric authentication failures, privacy and surveillance concerns, and the gap between "open" branding and closed, proprietary governance.<ref name="indiastack-watch"/><ref name="hrw">{{cite web|url=https://www.hrw.org/news/2018/01/13/india-identification-project-threatens-rights|title=India: Identification Project Threatens Rights|publisher=[[Human Rights Watch]]|date=13 January 2018|access-date=7 January 2025}}</ref>

== Origin of the term ==
The term "India Stack" was coined by [[ISPIRT|iSPIRT]], a technology industry think tank co-founded by Sharad Sharma in 2013. iSPIRT positioned the branding to describe separate government systems as a unified, exportable model of "[[digital public infrastructure]]" (DPI).<ref name="ft">{{cite news|url=https://www.ft.com/content/cf75a136-c6c7-49d0-8c1c-89e046b8a170|title=The India Stack: Opening the digital marketplace to the masses|newspaper=[[Financial Times]]|date=20 April 2023|access-date=7 January 2025}}</ref>

Critics characterise "India Stack" as a PR construct--branding separate closed systems as unified "open" infrastructure for international promotion. Each component ([[Aadhaar]] under [[Unique Identification Authority of India|UIDAI]], [[Unified Payments Interface|UPI]] under [[National Payments Corporation of India|NPCI]], [[DigiLocker]] under [[Ministry of Electronics and Information Technology|MeitY]], [[Ayushman Bharat Digital Mission|ABDM]] under [[National Health Authority|NHA]]) is closed-source and separately governed; the unified branding suggests cohesion and openness while the underlying systems remain proprietary and siloed.<ref name="indiastack-foss">{{cite web|url=https://indiastack.in/foss/|title=Is India Stack Open Source?|publisher=India Stack Watch|access-date=7 January 2025}}</ref>

=== Participation model ===
Unlike open protocols such as [[HTTP]], [[email]], or [[TCP/IP]] where anyone can implement independently, India Stack requires permission at every layer. There is no public [[Request for Comments|RFC]] process, no citizen representation on technical committees, and no mechanism to challenge design decisions before deployment.<ref name="indiastack-participate"/>

Researchers note this differs fundamentally from both the [[IETF]] model of "rough consensus and running code" and [[Free and open-source software|FOSS]] contribution models where rejected proposals can still be implemented independently. In India Stack, if a proposal is rejected, there is no alternative--the gatekeeper's decision is final.<ref name="indiastack-foss"/>

== Scale and adoption ==
India Stack components have achieved significant transaction volumes:

* '''UPI''': Over 10{{nbsp}}billion monthly transactions by 2023<ref name="npci">{{cite web|url=https://www.npci.org.in/|title=NPCI - National Payments Corporation of India|access-date=7 January 2025}}</ref>
* '''Aadhaar''': 1.4{{nbsp}}billion enrolments
* '''DigiLocker''': Over 150{{nbsp}}million registered users

Proponents credit India Stack with expanding financial inclusion through [[Pradhan Mantri Jan Dhan Yojana|Jan Dhan]] bank accounts, reducing subsidy leakage through [[Direct Benefit Transfer]], and enabling digital service delivery.

== Concerns and criticism ==

=== Welfare exclusion and documented denials ===
{{Main|Aadhaar#Threat of exclusion}}
Aadhaar-based biometric authentication for welfare distribution has been linked to documented exclusions and deaths. Research by economists including [[Reetika Khera]] of [[IIT Delhi]] has found significant exclusion of genuine beneficiaries.<ref name="indiastack-exclusion">{{cite web|url=https://indiastack.in/exclusion/|title=The Human Cost|publisher=India Stack Watch|access-date=7 January 2025}}</ref>

Key findings include:
* Between 2013-2021, 4.39{{nbsp}}crore (43.9{{nbsp}}million) ration cards were deleted nationally
* A 2020 [[Abdul Latif Jameel Poverty Action Lab|J-PAL]] study found 88% of cancelled ration cards in [[Jharkhand]] belonged to genuine beneficiaries, not fraudulent "ghost" entries<ref>{{cite web|url=https://www.povertyactionlab.org/|title=J-PAL Studies on Aadhaar and Welfare|access-date=7 January 2025}}</ref>
* The Right to Food Campaign documented 57 starvation deaths in nine Indian states from 2015 onwards, with at least 19 directly linked to Aadhaar-related denial<ref name="rtfc">{{cite web|url=https://www.righttofoodcampaign.in/|title=Right to Food Campaign|access-date=7 January 2025}}</ref>
* Of 42 hunger-related deaths documented between 2017-2019, 25 were linked to Aadhaar issues<ref name="wapo-khera">{{cite web|url=https://www.washingtonpost.com/news/theworldpost/wp/2018/08/09/aadhaar/|title=Aadhaar, India's ID system, is a cautionary tale|first=Reetika|last=Khera|publisher=[[The Washington Post]]|date=9 August 2018|access-date=7 January 2025}}</ref>

Documented cases include Santoshi Kumari (11, Jharkhand, 2017), Arjun Hembram (11, Odisha, 2023), and others.<ref name="indiastack-exclusion"/>

[[Human Rights Watch]] documented 2.5{{nbsp}}million families in [[Rajasthan]] denied ration supplies between September 2016 and June 2017 due to Aadhaar issues. The report also found children without Aadhaar excluded from government schools and hospitals demanding Aadhaar enrolment before issuing birth certificates.<ref name="hrw"/>

=== Biometric authentication failures ===
Studies have documented significant biometric authentication failure rates:<ref name="cis">{{cite web|url=https://cis-india.org/internet-governance/blog/UID_Questions_without_Answers|title=UID: Questions without Answers|first=Usha|last=Ramanathan|publisher=[[Centre for Internet and Society (India)|Centre for Internet and Society]]|access-date=7 January 2025}}</ref>

* 6-12% fingerprint authentication failure rates among manual labourers, construction workers, and farmers
* Fingerprints degrade due to age, manual labour, and certain medical conditions
* Elderly people have degraded fingerprints; children's biometrics are unstable
* In 2023, UIDAI acknowledged 54+ hours of service downtime due to OTP delays and server issues

A 2018 analysis estimated that "two to five per cent of the Indian population would be excluded" due to biometric failures alone.<ref name="cis"/>

=== Facial authentication expansion (2023-2025) ===
Despite documented fingerprint exclusion, states began adding facial authentication requirements. [[Rajasthan]] mandated facial authentication for pensioners via the RAJSSP app in February 2023. Data from January-April 2025 showed:<ref name="wire-facial">{{cite web|url=https://thewire.in/rights/no-match-rajasthans-push-for-facial-authentication-on-pensioners-leaves-many-behind|title=No Match: Rajasthan's Push for Facial Authentication on Pensioners Leaves Many Behind|publisher=[[The Wire (India)|The Wire]]|date=2025|access-date=7 January 2025}}</ref>

* Facial authentication success rate: 69.11% (nearly 1 in 3 fail)
* Fingerprint authentication success rate: 76.27%
* OTP had 90%+ success rate but was deemed "unreliable" by authorities
* The system was tested on only 15-20 people before statewide rollout to 600,000+ pensioners in [[Jaipur]] district alone

Despite 30% failure rates, UIDAI reported 50{{nbsp}}million+ facial authentication transactions monthly since 2023.<ref name="wire-facial"/>

=== Consent issues ===
Critics argue that consent is structurally compromised when Aadhaar authentication is mandatory for essential services. UIDAI claims authentication requires "explicit consent," but researchers note consent is meaningless when refusal means exclusion from:<ref name="indiastack-exclusion"/><ref name="idr">{{cite web|url=https://idronline.org/article/rights/infrastructures-of-exclusion-how-e-kyc-impacts-access-to-food/|title=Infrastructures of Exclusion: How e-KYC Impacts Access to Food|publisher=IDR Online|access-date=7 January 2025}}</ref>

* Food rations under [[Public Distribution System (India)|Public Distribution System]]
* Pension disbursement
* Bank account access ([[Know your customer|KYC]] requirements)
* [[Liquefied petroleum gas|LPG]] subsidies
* Government employment wages ([[Mahatma Gandhi National Rural Employment Guarantee Act, 2005|MGNREGA]])
* Healthcare access (ABDM)
* Vehicle toll payment ([[FASTag]] - mandatory by law)

=== Privacy and surveillance ===
{{Main|Surveillance in India}}
The centralised nature of India Stack creates surveillance infrastructure concerns:<ref name="indiastack-surveillance">{{cite web|url=https://indiastack.in/surveillance/|title=Surveillance Architecture|publisher=India Stack Watch|access-date=7 January 2025}}</ref>

* Centralised biometric database of 1.4{{nbsp}}billion people
* Authentication logs enabling tracking of citizens' access to services
* Cross-linking of identity, financial, health, and location data
* Limited independent oversight and RTI exemptions

The [[Supreme Court of India]] ruled privacy a [[Fundamental rights in India|fundamental right]] in August 2017 ([[Justice K. S. Puttaswamy (Retd.) and Anr. vs Union of India and Ors.|Justice K.S. Puttaswamy v. Union of India]]).<ref>{{cite web|url=https://thewire.in/law/supreme-court-aadhaar-right-to-privacy|title=Right to Privacy a Fundamental Right, Says Supreme Court in Unanimous Verdict|publisher=[[The Wire (India)|The Wire]]|date=24 August 2017|access-date=7 January 2025}}</ref>

In September 2018, the court upheld Aadhaar's constitutional validity but struck down Section 57 allowing private sector use. The government subsequently amended laws through ordinances to restore private sector access.<ref name="techcrunch">{{cite web|url=https://techcrunch.com/2025/02/02/india-expands-aadhaar-authentication-for-businesses-raising-privacy-concerns/|title=India expands Aadhaar authentication for businesses, raising privacy concerns|publisher=[[TechCrunch]]|date=2 February 2025|access-date=7 January 2025}}</ref>

=== Open source claims ===
While described as "open APIs," India Stack does not follow [[free and open-source software]] principles:<ref name="indiastack-foss"/>

* Source code is not publicly available
* No public contribution or proposal mechanism exists
* Alternative implementations are legally prohibited
* Governance is not participatory
* Cannot be [[Fork (software development)|forked]] or independently operated

The [[Financial Times]] noted these concerns in 2023, questioning claims of openness.<ref name="ft"/>

=== Accountability gaps ===
Several structural accountability issues have been identified:<ref name="indiastack-audit">{{cite web|url=https://indiastack.in/audit/|title=Can You Audit It?|publisher=India Stack Watch|access-date=7 January 2025}}</ref>

* UIDAI is exempt from [[Right to Information Act, 2005|RTI]] for certain categories of information
* Only UIDAI can sue for Aadhaar-related issues; individuals cannot sue UIDAI under Section 47
* Aadhaar deactivations occur without prior notice
* A 2022 [[Comptroller and Auditor General of India|CAG]] report found UIDAI takes no responsibility for deficient biometric capture
* No public auditing of authentication success/failure rates across welfare programs

=== Digital divide ===
The [[COVID-19 pandemic in India|COVID-19 vaccination]] rollout via [[CoWIN]] highlighted digital divide issues:<ref name="sflc">{{cite web|url=https://sflc.in/sflcin-writes-pmo-mohfw-nha-raising-concerns-related-cowin/|title=SFLC.in Raises Concerns Related to CoWIN|publisher=Software Freedom Law Centre, India|date=2021|access-date=7 January 2025}}</ref>

* CoWIN required smartphone, internet access, and digital literacy
* 200-280{{nbsp}}million Indians (33-45% of 18-44 age group) had no or poor internet access
* 25% of India's population had no smartphone
* No offline registration option initially
* Supreme Court (May 2021) noted "CoWIN not accessible to persons with disabilities"

== Court cases ==

=== Key judgments ===
* '''[[Justice K. S. Puttaswamy (Retd.) and Anr. vs Union of India and Ors.|Justice K.S. Puttaswamy v. Union of India]] (2017)''': Nine-judge bench unanimously ruled privacy a fundamental right
* '''Justice K.S. Puttaswamy v. Union of India (2018)''': Five-judge bench upheld Aadhaar's validity but struck down Section 57 (private sector use) and Section 33(2) (disclosure without judicial oversight)
* '''Koili Devi v. Union of India''': Petition filed by Santoshi Kumari's mother challenging deletion of ration cards
* '''Orissa High Court (May 2023)''': Ruled welfare schemes cannot exclude on grounds of lacking Aadhaar or mobile phone
* '''P. Pushpam v. UIDAI (Madras HC, 2025)''': Ruled Aadhaar correction is a fundamental right

== e-KYC mandate (2024) ==
In June 2024, the government directed 100% e-KYC compliance for all ration card holders. [[Odisha]] suspended rice distribution for 20+ lakh (2{{nbsp}}million+) eligible individuals for e-KYC non-compliance. The Right to Food Campaign urged the government to halt e-KYC and remove exclusionary digital measures from [[Public Distribution System (India)|PDS]].<ref name="idr"/>

== International adoption ==
Several countries have expressed interest in adopting India Stack components. [[Sri Lanka]], [[Morocco]], the [[Philippines]], [[Guinea]], [[Ethiopia]], and [[Togo]] have reportedly started using components.<ref>{{cite web|url=https://theprint.in/economy/world-rushes-to-adopt-the-india-stack-while-upi-goes-global/1373900/|title=World rushes to adopt the 'India Stack' while 'UPI' goes global|publisher=[[ThePrint]]|date=15 February 2023|access-date=7 January 2025}}</ref>

Critics note that countries adopting the model may also adopt its structural issues regarding exclusion, consent, and accountability.<ref name="indiastack-watch"/>
