IDFC Fastag for Car  (Transparent)

It's a small sticker that you stick on your car's windshield. It's about the size of a credit card. The sticker has a special chip inside and uses something called RFID technology to work. Depending on where you get it from, it might look a bit different, but it's usually a rectangular sticker with a logo or a unique number on it. On the back, there's sticky stuff so you can easily stick it to your windshield. Inside, there's a tiny chip that stores info about your car and your prepaid account. When you drive through a toll plaza, the chip talks to the toll booth's machine wirelessly, and the toll money gets deducted from your prepaid account automatically. You can manage and put more money into your prepaid account online or at certain places in person. Overall, it's a super handy way to pay tolls without needing cash. It makes driving through toll booths faster and less crowded."
