    Characters of countless sci-fi films have relied on iris scans to unlock hidden rooms, power up advanced gadgets, or authenticate their identities in a tech-centric world. What once was only a Hollywood fantasy is now becoming a reality, with similar applications just around the corner. These days, it’s not unusual to hear about shopping malls in cities like Barcelona featuring tiny booths where visitors scan their eyes. The concept is puzzling, especially when they explain that the goal is to “scan your iris to give you cryptocurrencies.”

    Worldcoin, one of Sam Altman’s (director of OpenAI, creators of ChatGPT) ventures, has recently gained increased attention due to their new initiative: offering money in exchange for iris scans. Worldcoin scans the biometric data of the eye and then compensates individuals with cryptocurrency. However, many ask the same questions: What (1)____ Worldcoin gain from our iris? What (2)____ they really planning to do with it? Why (3)____ the iris so important? How (4)____ it affect your privacy?

    Unlike data such as phone numbers, credit cards, or passwords, biometric data is unchangeable. Biometric data includes traits that can be used to identify you, such as your voice, fingerprint, or iris. They are inherently yours and non-transferable. Sharing biometric data could expose individuals to risks of tracking and surveillance, potentially enabling identification without consent through various technologies. Often without realizing it, people have given permission for their data to be sold.

    After carefully studying the legality of this practice, Spain has banned these operations and is removing the stands and iris scanners used by Worldcoin. In countries like France or Brazil, Worldcoin has also faced bans on conducting their activities, while claiming they’re leaving voluntarily rather than because it’s illegal.
