Key takeaways
- NCMC ("One Nation One Card") lets you use a single tap-and-go card on metros, city buses, toll plazas and retail across India.
- Transit fares are deducted from an offline wallet (service area) stored directly on the card chip (up to ₹2,000), so gates open in under 300 milliseconds without cellular signal.
- Accepted on Delhi Metro (all lines), Mumbai Metro (Line 3, 2A, 7, Line 1), Bengaluru Namma Metro & BMTC buses, Chennai CMRL & MTC buses, Pune, Ahmedabad, Hyderabad, and UP Metros.
- Available as prepaid transit cards at station counters, or as bank-issued RuPay debit and credit cards with built-in NCMC chips.
Standing in line for physical tokens or generating mobile QR codes every time you enter a metro station is frustrating. India's National Common Mobility Card (NCMC)—popularly known as the "One Nation, One Card" initiative—was designed to fix exactly that. A single contactless card can now tap you into the Delhi Metro, Mumbai Metro Line 3, Bengaluru's Namma Metro, BMTC buses, Chennai Metro, and Pune Metro without buying separate city smart cards.
What is an NCMC card?
Developed by the Ministry of Housing and Urban Affairs (MoHUA) in partnership with the National Payments Corporation of India (NPCI) and Centre for Development of Advanced Computing (C-DAC), NCMC is an open-loop EMV contactless standard. Unlike legacy closed-loop transit cards (such as the original DMRC blue card or legacy CMRL smart cards) that only worked on one specific rail network, an NCMC card is fully interoperable across all transit systems that have upgraded their Automatic Fare Collection (AFC) gates.
How the Dual-Interface Offline Wallet works
The biggest engineering breakthrough of an NCMC card is its dual-interface architecture:
| Feature | Online Banking Balance | Offline Transit Balance (Chip Wallet) |
|---|---|---|
| Where it lives | Your bank account / primary wallet | Directly inside the secure microchip on the card |
| Used for | ATM withdrawals, POS shopping, online eCommerce | Metro AFC gates, bus conductors' handheld POS, tolls |
| Speed | 2 to 5 seconds (needs network authentication) | < 300 milliseconds (tap and open gate instantly) |
| Maximum Limit | Account balance / credit limit | ₹2,000 (mandated by RBI for offline transit) |
| Connectivity | Requires active internet / cellular connection | 100% offline—works deep underground in tunnel stations |
When you tap at a metro turnstile, the gate reader reads and deducts the balance directly from the encrypted chip on the card itself without pinging a central bank server over the internet. This ensures thousands of commuters can pass through gates during rush hours without server lags or network timeouts.
City-by-City NCMC Acceptance Status (2026)
Here is where NCMC is currently operational across major transit networks in India:
- Delhi (DMRC): 100% operational across all lines, including the Airport Express Line. DMRC also issues co-branded Airtel Payments Bank RuPay NCMC cards at station counters.
- Mumbai: Fully operational on Mumbai Metro Line 3 (Aqua Line underground), Lines 2A & 7, Line 1 (Versova-Ghatkopar), and on BEST / Chalo buses.
- Bengaluru (BMRCL & BMTC): Namma Metro issues the RBL Bank NCMC card. Since June 2026, over 11,000 BMTC city bus ticketing machines accept all NCMC cards.
- Chennai (CMRL & MTC): Legacy travel cards were discontinued in May 2026 in favor of the Singara Chennai SBI NCMC card, which gives a 20% fare discount and works on MTC buses.
- Pune: Operational on Line 1 (Purple), Line 2 (Aqua) and Puneri Metro Line 3 via the One Pune Card (HDFC Bank) or any bank NCMC card.
- Ahmedabad & Gandhinagar (GMRC): Accepted across Phase 1 & Phase 2 (connecting Ahmedabad to GIFT City and Gandhinagar) with a 10% fare discount.
- Hyderabad (L&T Metro): Counters issue the PhonePe RuPay On-The-Go NCMC card.
- Noida Metro (NMRC): Fully operational across all 21 Aqua Line stations since August 2026 with the SBI NMRC City1 card.
- UP Metro (Lucknow, Kanpur, Agra): UPMRC GoSmart NCMC cards provide a 10% discount on every trip.
Which banks issue NCMC cards?
You can get an NCMC card through two primary routes:
- Bank Debit / Credit Cards: Most major public and private banks (including SBI, HDFC Bank, ICICI Bank, Axis Bank, RBL Bank, Canara Bank, and Punjab National Bank) now issue RuPay contactless debit or credit cards with the NCMC logo on the back. When requesting a new or replacement card from your bank, choose a RuPay NCMC variant.
- Co-branded Transit Cards at Station Counters: If you don't want to use your primary bank account, you can walk up to any metro customer care counter and buy a prepaid NCMC card (such as Airtel Payments Bank at DMRC, SBI Singara Chennai at CMRL, HDFC One Pune card in Pune, or RBL Namma Metro in Bengaluru) for ₹50–₹150.
How to activate and top up your NCMC card
Because the transit balance lives on the physical chip, topping up an NCMC card involves two quick steps:
- Step 1 (Payment): Pay online via your bank app, UPI (Paytm, PhonePe, Google Pay, Amazon Pay) or at the station customer care counter.
- Step 2 (Chip Writing at AVM): Tap your card on the Add Value Machine (AVM) or Ticket Reader at any metro station. The machine writes the newly credited funds onto the chip. (Some NFC-enabled Android smartphones also allow writing the balance directly via the issuing bank's mobile app).
Key commuter tips & rules to avoid gate penalties
- Maintain Minimum Balance: Most metro systems require a minimum offline balance (typically ₹50 in Delhi, ₹60 in Bengaluru, ₹50 in Mumbai) to open the entry gate. If your chip balance is below this threshold, the flap will not open.
- Entry & Exit Mismatch: You must always tap the exact same NCMC card at both entry and exit. If you tap Card A on entry and Card B on exit, the system cannot calculate your journey distance and will block your card or charge the maximum possible line fare.
- Same-Station Exit Rule: If you enter a station and exit the same station within 20–30 minutes, a nominal minimum fare (usually ₹10) is deducted. Staying inside for hours will trigger an overstay penalty at the exit AFC gate.

FAQs
Can I use my regular Visa or Mastercard credit card at metro gates?
Standard Visa and Mastercard credit cards cannot be tapped directly at AFC gates unless they have explicit NCMC transit certification enabled by the bank. Currently, RuPay NCMC credit cards (such as RBL Bank RuPay) and NCMC prepaid/debit cards work across all NCMC turnstiles.
What happens if my NCMC card is lost or stolen?
Because the offline transit balance (up to ₹2,000) is stored on the physical chip, money already loaded into the offline wallet cannot be recovered if lost—similar to physical cash. However, your primary bank account balance remains safe. You should block the card immediately in your bank app.
Does one NCMC card work in other cities?
Yes. If you bought an NCMC card from Delhi Metro (DMRC), it will work seamlessly at Mumbai Metro Line 3, Bengaluru Namma Metro and BMTC buses, Chennai Metro, and Pune Metro gates without any reconfiguration.
Is there a fee to get an NCMC card?
Station counters typically charge a one-time issuance fee of ₹50 to ₹150, plus a mandatory initial wallet load of ₹50 to ₹100. Bank-issued NCMC debit cards are often provided free or under standard annual debit card charges.
