Chennai Metro Rail Limited (CMRL) has announced a complete switch to the Singara Chennai Card – National Common Mobility Card (NCMC), effective August 1, 2025. From this date, further top-ups for existing CMRL Travel Cards (Contactless Smart Cards) will be discontinued across all 41 metro stations.
The Singara Chennai NCMC was initially introduced on April 14, 2023, as a supplement to the existing travel cards. While passengers can continue to use the remaining value on their old CMRL Travel Cards until it is exhausted, a seamless transition process is in place. Once a card’s residual value falls below ₹50, passengers can surrender it at any CMRL ticketing counter to receive a Singara Chennai NCMC as a free replacement, with their original deposit and remaining balance transferred to the new card.
Other ticketing systems, such as QR tickets, will continue to operate as usual. CMRL expressed its anticipation for continued patronage as it transitions to this integrated mobility solution.
