Frequently Asked Questions
How do I recharge the Chennai Metro Smart Card?
At any ticket machine in any CMRL station using cash, debit/credit card, or UPI (GPay, PhonePe, Paytm). Minimum recharge is ₹100. Balance reflects immediately.
Is the token a coin or a card?
Chennai Metro uses a token card — a flat plastic card (not a coin). You tap it on the reader to enter and exit. Deposit the token at the exit gate when leaving.
Can I use the Smart Card on MTC buses?
No — the Metro Smart Card is metro-only. MTC buses require separate payment (cash or MTC smart card). There is no unified transit card for both systems yet.
How do I get a refund on my Chennai Metro Smart Card?
Visit any CMRL customer care centre with the card and ID. The ₹50 deposit plus remaining balance is refunded in cash. No processing fee.
