FASTag ₹100 is a free Android application designed for users looking to generate a UPI ID specifically for recharging their FASTag accounts. This user-friendly tool allows individuals to input their vehicle number, select their bank, and determine a recharge amount starting from ₹100, circumventing the typical ₹500 minimum set by other applications. The app does not integrate UPI payments directly but instead focuses on generating a unique UPI ID that users can utilize through their preferred UPI-enabled payment platforms.

One of the standout features of FASTag ₹100 is its zero-commission structure, ensuring that users can recharge without incurring any fees. The app generates revenue solely through in-app advertisements, making it entirely free to use. However, users should be cautious of the regulatory requirement to maintain a minimum balance of ₹200 in their FASTag wallet while traveling to avoid penalties. Overall, FASTag ₹100 simplifies the process of managing FASTag recharges, making it accessible and straightforward.
