Internet explains what the symbol means
The post quickly attracted responses from users eager to solve the mystery.
One user explained, "That dot, or small gold rectangle, on your new Indian passport cover marks it as an e-Passport with an embedded RFID chip. It's the standard international biometric symbol printed at the bottom of the front cover."
Another user echoed the explanation, writing, "You are right. It's an embedded chip."
Several people highlighted the growing use of e-Passports around the world. "It is E-Passport. This is the international standard. Very few Indians have it. Older passports will be phased out in the next one to two years," claimed one commenter.
Others pointed to the technology behind the feature. "There is an inbuilt chip in the new passport where, using a particular app, all details of the passport can be scanned and verified," wrote a user.
Some commenters also noted that similar technology is already widely used internationally. "It's a biometric chip that helps in scanning passports. Nearly every country has a similar thing for their passports," one person said.
The discussion also impressed many users, with one remarking, "It's amazing how a tiny detail on a passport can have such an important function behind the scenes."
