Bengaluru techie creates realistic-looking PAN, Aadhar using Nano Banana: ‘Twitterpreet Singh’

With pictures of AI-generated PAN and Aadhar cards, the Bengaluru techie prompted mixed reactions on social media.

“Nano Banana is good but that is also a problem. It can create fake identity cards with extremely high precision. The legacy image verification systems are doomed to fail. Sharing examples of pan and aadhar cards of an imaginary person,” wrote Harveen Singh Chadha.

The two pictures he shared show the cards, which look realistic at first glance. However, once you look closer, it becomes apparent that the cards are fake. Also, they both have the Gemini AI watermark.

Where did he get the idea?

In conversation with HT.com, Chadha shared, “I experiment a lot with model capabilities. Earlier models from google used to heavily nerf celebrity faces or intentionally introduce errors when you tried tasks like these. But with the launch of Nano Banana Pro, things have changed. The model is noticeably more intelligent, refuses less and makes far fewer mistakes especially with the structure and layout.”

He added, “It still isn’t perfect with fonts or fine grained text, but the jump in accuracy made me curious about how far it could go. That’s what led me to test it on PAN and Aadhaar formats.”

What did social media say?

The post prompted mixed reactions. While some shared that it would pose security threats, others expressed that it is nothing to worry about.

An individual shared, “Gemini adds hidden fingerprints called SynthID, which can be verified through that. It is also available in the Gemini APP.” With the latest Gemini 3 update, Google has added a feature that allows users to upload a picture and ask the AI model if it was created using Gemini. Chadha replied, “No one is gonna scan every proof through the Gemini app.”

Another added, “Scanning the QR on the Aadhar and actually verifying it will start becoming the norm soon because of this. And the new Aadhaar app also makes it easy for private hotels and places to verify an Aadhaar themselves.”

A third joked, “A clear picture on an Aadhar card makes it a fake immediately.” A fourth wrote, “This is going to be a serious security threat. But this is a damage that happens with any technological shift.”

While talking about the mixed reactions on social media, Chadha told HT.com, “Some people agree it’s scary and feel this level of AI accuracy is concerning. Some say SynthID exists but verifying SynthID properly is still a learning curve and not trivial for most people. Also watermarks at the side of the image can be cropped. Others argue this was always possible with Photoshop which is true but tools like Nano Banana drastically lower the entry barrier and make it easier for anyone.”

“Create awareness, not fear”

Explaining his intention behind the post, the techie said that it was to create awareness. “A lot of people are scared but the intention behind the post was not to create fear, it was to create awareness. I wanted to show what today’s AI models are capable of because they work unbelievably fast and with far fewer errors than older methods. This also calls for improving our traditional verification systems at the same pace these models are improving.”

How did he create the fake cards?

When asked, he replied, “As a responsible tech person, I cannot share the prompt or methodology used to generate these fake cards.”
