NHAI Launches OneTag to Let Users Switch FASTag Banks

The National Highways Authority of India has launched OneTag, a facility allowing users to switch their FASTag issuer bank without replacing the physical tag. Announced at the Global Fintech Fest 2026 in Mumbai, the service runs through the RajmargYatra app. The FASTag ID stays unchanged, and any remaining wallet balance is refunded by the previous issuer.
