Iris biometrics, once confined to science fiction, has become a reality with Worldcoin, a project led by Sam Altman, CEO of OpenAI (known for creating ChatGPT). The proposal of scanning users’ irises in exchange for cryptocurrency has sparked intense debate regarding privacy, security, and the future of digital identification. But is this really an iris sale? What are the risks involved? Let’s break down the key points of this controversy.

Iris Scanning and Payments Banned in Multiple Countries: What’s Behind These Decisions?
As of March 25, several countries, including Brazil, France, and Germany, have raised concerns or outright prohibited Worldcoin from compensating participants. The Brazilian National Data Protection Authority (ANPD), under the Ministry of Justice, has argued that financial incentives could undermine users’ free will. Similarly, European regulators have scrutinized the company over data privacy concerns. Additionally, Worldcoin must disclose who is responsible for data processing on its official website.
While iris biometrics have gained popularity worldwide for their convenience and security, they are now under scrutiny by multiple regulators across different regions.
Worldcoin offers cryptocurrency tokens (Worldcoin tokens) as compensation for users who allow their irises to be scanned using a device called the Orb (Fig.1). The company behind the project, Tools for Humanity (TfH), claims the goal is to create a global digital ID system that verifies human identity online, distinguishing real people from bots and artificial intelligence. However, the practice has been informally labeled as an “iris sale,” leading to widespread controversy:
- Not Exactly a Sale: TfH insists that this is not a sale of iris data but rather the creation of a credential for online identity verification. Users receive tokens as an optional incentive. The company firmly denies selling iris data and states that it does not store iris images, only a numerical code derived from the scan.
- Contradictions and Warnings: Despite these assurances, concerns remain about biometric data collection. Iris biometrics are irreversible—once compromised, they cannot be changed. Additionally, the lack of clarity regarding the future use of these data and the risk of leaks pose significant threats. Reports indicate varying compensation amounts, from approximately $40 to $150, raising further skepticism. Users should seek official information from the company and rely on credible sources.
- Surging Adoption in Multiple Countries: The project gained traction in Brazil, Mexico, and Indonesia in late 2024, with verification centers spread across major cities. In these regions, hundreds of thousands of people reportedly scanned their irises, drawn by the promise of easy money—now a prohibited practice in some countries.
- Security and Privacy Concerns: The main concern is the security and privacy of biometric data. If iris data were leaked, it could lead to identity theft and fraud. While blockchain technology offers a degree of security, it is not immune to cyberattacks.
What is Iris Scanning, and Why Is It Gaining Traction?
Iris scanning is an advanced biometric technology that identifies individuals based on the unique patterns in their eyes. In recent years, it has emerged as an efficient authentication method for payments and secure access to services, promising strong fraud prevention. With increasing digitalization, it was seen as the future of secure transactions, eliminating the need for passwords or physical cards.
While countries like India and Japan have embraced this technology, others, including Germany and Canada, have imposed strict regulations or expressed skepticism. These decisions raise fundamental questions about privacy, data security, and ethical considerations surrounding emerging technologies.
Lessons from Countries Leading in Iris Biometrics
| Application/Context | Benefits (Efficiency/Inclusion) | Concerns (Privacy/Control) | Country/Region |
|---|---|---|---|
| Government Services & Financial Inclusion | Facilitates access to essential services, promoting inclusion in underserved areas. | Large-scale biometric data breaches raise concerns about citizen data security. | India |
| Airports & Transportation | Enhances efficiency and security, reducing wait times and fraud. | Mass biometric data collection raises concerns about government surveillance. | Japan |
| Payments & Transactions | Increases convenience and personalization in digital payments. | Excludes populations without access to compatible devices, exacerbating inequality. | USA |
| Banking Authentication | Prevents fraud more effectively than traditional methods. | Overreliance on biometrics can create vulnerabilities in cases of system failures or cyberattacks. | European Union |
| Border Control & Identity Verification | Speeds up complex security processes. | In countries with weak regulations, biometric data can be exploited or sold. | UAE |
| Data Protection Regulations | Promotes stringent data privacy laws to protect users. | Overregulation may slow down innovation and adoption of new technologies. | Germany, Canada |
Critical Questions for the Public to Consider
The growing restrictions on iris-based payments mark a pivotal moment in the discussion of emerging technologies. More importantly, these decisions invite deeper reflection. Some key questions include:
- How much do we really understand about how our biometric data is used and stored?
- Are these prohibitions valid precautions or technological setbacks?
- Are we prepared to manage the risks of biometric authentication, or do we need more regulation and transparency?
- How can we balance technological innovation with the protection of individual rights?
Recommendations Before Using Biometric Technologies
Given the complexities of this debate, it is essential that users make informed decisions before adopting any biometric technology. Consider the following:
- Understand how your data is used: Before sharing biometric information, research how it is stored, processed, and protected. Always ask, “Who has access to this data, and for what purpose?”
- Read terms of service and privacy policies: These documents, often overlooked, contain critical details about user rights and data usage restrictions.
- Choose trusted services: Opt for companies with a transparent track record in data protection and compliance with global regulations.
- Assess the necessity: Weigh the convenience of using the technology against its potential risks. In many cases, traditional authentication methods may be safer.
- Advocate for stronger regulations: Demand greater transparency from governments and corporations regarding the ethical use of biometric data.
The Future of Biometrics Worldwide
One thing is certain: the current bans and restrictions are not the final word on this issue. As technology advances, biometrics will continue to be debated across various sectors, and public involvement is crucial in shaping policies. Will governments find a way to balance innovation, privacy, and security? Or does this issue call for a deeper transformation in how we manage technology?
The prohibition of iris-based payments may be just the beginning of a broader conversation about digital identity technologies. The outcome of this debate depends on all of us. How far are we willing to go for the sake of convenience?
This article aims to present the iris scanning controversy clearly and informatively, highlighting the risks and inconsistencies involved. Whether to participate in the project remains an individual decision, but access to accurate information is crucial for making an informed choice.
Finally, this is an evolving issue. New developments can emerge at any time, making it essential for readers to stay informed through reliable sources.
