Frequently Asked Questions (FAQ)

ABT
  1. What is the Account-Based Ticketing (ABT) System?

    The Account-Based Ticketing (ABT) System enables commuters to use credit, debit or pre-paid cards with contactless function for fare payments. During the pilot, only Singapore-issued Mastercard/Visa/NETS contactless bank cards will be accepted. There will be no need for upfront top-ups when using your credit card or debit card for fare payments.

    Similar to any Mastercard/Visa/NETS contactless purchases, bus and train transactions will be processed, accumulated and charged to your credit, debit or pre-paid cards. Commuters will be able to track and view their journey and fare history via the TransitLink ABT Portal or TransitLink mobile app.

  2. Why introduce the ABT System?

    This initiative ties in with one of the key pillars of Singapore’s Smart Nation vision – Smart Mobility, and taps on digital payments technology to provide commuters with a more convenient way to pay for public transit, as well as an enhanced travel experience.
  3. What are the benefits of the ABT System?

    The ABT System will eliminate the need for a separate transit card, as well as the hassle of topping up.

    In addition, the ABT System will enable commuters to track and view their journey and fare history at their convenience via TransitLink ABT Portal or TransitLink mobile app.
  4. How do I participate in this pilot launch?

    Mastercard cardholders may visit the TransitLink ABT Portal or TransitLink mobile app to register for an ABT Account and add their Mastercard contactless bank card to participate in the pilot.

    Selected Visa cardholders may refer to the pilot invitation for information on how to participate in the pilot.

    The $0.10 earmark will be released between 7 - 30 days, depending on your Issuing Bank. If you have any queries, you may contact your Issuing Bank for assistance.
  6. What is the difference between using contactless bank cards under the ABT System and contactless bank cards with EZ-Link or NETS FlashPay functionality?

    The main difference is that commuters with contactless bank cards can only use their credit, debit or pre-paid cards with Mastercard/Visa/NETS contactless function for fare payments directly, subject to the availability of credit/funds in their credit, debit or pre-paid cards. The travel transactions will be processed, accumulated and charged to their credit, debit or pre-paid cards.

    For commuters using contactless bank cards with EZ-Link/NETS FlashPay functionality, the current default payment mode for transit usage is the EZ-Link/NETS FlashPay function. Should you wish to change your payment mode to Mastercard/Visa contactless payment after registration, please refer to Question 7.
  7. How do I enable my Mastercard/Visa contactless bank card for transit?

    For Mastercard/Visa contactless bank cards that do not have EZ-LINK/NETS FlashPay functionality, no additional action is required after you linked them to your ABT Account.

    For contactless bank cards that come with EZ-Link/NETS FlashPay functionality, the EZ-Link/NETS FlashPay function will be the default payment mode for transit. You will need to visit the General Ticketing Machines at any train station to switch to contactless payment mode. This can be performed five (5) days after receiving the confirmation email of your card registration. Please note that your EZ-Link/NETS FlashPay purse has to be active in order to switch to contactless payment mode for ABT.

  8. How do I switch the payment mode of my Mastercard/Visa contactless bank card back to EZ-Link/NETS FlashPay functionality?

    After selecting “Check Transit Payment Mode”

  9. Will the remaining stored value in the EZ-Link/NETS FlashPay purse of my registered Mastercard/Visa contactless bank card be automatically refunded to me when I switch to contactless payment at the General Ticketing Machiness?

    No, it will not be refunded automatically. You may present your card at any TransitLink Ticket Office for a refund of the remaining value in the EZ-Link/NETS FlashPay purse.

    Upon refund, you will not be able to switch the payment mode of your contactless bank card back to EZ-Link/NETS FlashPay functionality in future.
  10. How do I remove my Mastercard/Visa contactless bank card from the ABT Portal?

    You will be able to remove a card previously registered to your ABT Account from the “My Cards” page on the TransitLink ABT Portal or TransitLink mobile app. Once the selected card is removed, all the existing and future transaction and travel history of the card cannot be viewed from the portal.

    Do note that removing your card from your ABT Account does not automatically switch your card’s default payment mode to EZ-Link/NETS FlashPay function for transit. You will need to do the switch at the General Ticketing Machines located at all MRT and LRT stations.

  3. May I tap my wallet or bag at the card reader?

    If you have more than one contactless payment card (Mastercard/Visa/NETS contactless bank cards, ez-link cards, NETS FlashPay cards or others) in your wallet or bag, you may experience card clash. An error message may appear and you may be denied entry or exit, or charged more than once because multiple cards are detected.

    To avoid card clashes, please remove your registered Mastercard/Visa/NETS contactless bank card from your wallet or bag to tap at the card reader to enter and exit, and always tap in and out with the same registered card. Otherwise, it will be considered as two separate fare transactions.
  4. What should I do if I lose my Mastercard/Visa/NETS contactless bank card that was registered for transit?

For NETS users, please refer to Question 1 in "Registration and Activation of NETS Contactless Bank Cards" section.

    In the event that the pilot programme is fully subscribed, you will not be able to add a card for transit usage at that point.

    For invited Visa cardholders with replacement card, you would need to contact your Issuing Bank to take part in the pilot again.

Fares and Billing
  1. Can I use my contactless bank card payment to make payment for all train and public bus services?

    Yes, you can pay for both train and public bus fares (basic, premium and express bus services) with your Mastercard/Visa/NETS contactless bank card under the ABT System, except for private buses.

    Please note that for premium bus services, your Mastercard/Visa/NETS contactless bank card can be used to pay for fares only if they are operated by public transport operators (PTOs) and not private operators. All PTOs-operated buses (basic, premium and express bus services) are installed with a standard card reader as shown below.

  2. Are there any changes to the fares when using my Mastercard/Visa/NETS contactless bank card for transit?

    No, the fares charged using contactless bank cards are the same as card fares. Please refer to www.ptc.gov.sg/regulation/bus-rail/fare-structure for more information on fares.

    Please note that concessionary fares and travel passes are not available as part of this pilot.
  3. How would I be billed?

    The transactions will be processed and charged to your contactless bank cards with the merchant descriptor name - BUS/MRT. Depending on your Issuing Banks, postings may not be reflected immediately in your credit/debit/prepaid card accounts.

    For Mastercard and NETS contactless bank cards, fare charges will be accumulated for up to 5 days or after a total of $15 is spent on transit fares, whichever is earlier.

    For Visa, fare charges will be accumulated daily. You will be able to see the aggregated charges on the card statement after 4 days.

    To view the breakdown of the aggregated fares, please log into the TransitLink ABT Portal or TransitLink mobile app.
  4. Will the fare amount be displayed on the reader when I tap to exit?

    No, the reader will only display “Bank Card Usage”. However, you will be able to view the details of each transaction in your ABT Account on the TransitLink ABT Portal or TransitLink mobile app.
  5. Why am I unable to see the fare charged at the point of exit?

    Due to the system nature of ABT, the computation of fare calculation is not instantaneous and hence the fares charged are not displayed at the point of exit.

    You will be able to find the details of each transaction in your ABT Account on the TransitLink ABT Portal or TransitLink mobile app.
  6. What should I do if there are any discrepancies in my transactions/billings history?

    If there are any discrepancies in your travel transactions or billings, you may submit your claims for the travel transactions of the cards that are linked to your ABT Account via the “My Claims” page on the TransitLink ABT Portal or TransitLink mobile app. Claims can only be filed for transactions that are up to 14 days after the date of incident.

    For commuters who have not signed up for an ABT Account or link their cards to their account, please do so on the TransitLink ABT Portal or TransitLink mobile app. Please note that you can only view up to the last 90 days of your transactions history.
  7. I have a posting of Incomplete Rail Transaction/Rail Overstay Charge in my statement. Why is this so?

    A posting of Incomplete Rail Transaction will be reflected in your statement as “Missing Entry” / “Missing Exit”, if the point of entry or exit is not recorded in the ABT System. A flat fare will be charged, regardless of the distance travelled.

    A posting of Rail Overstay Charge will be reflected in your statement as “*”, if you exceed the time limit allowed for exiting a station. In this case, you will be charged an additional fee of $2.00, on top of the actual fares incurred.
  8. Why is there an earmarked amount on my card?

    For Mastercard and NETS contactless bank cardholders, a pre-authorisation fee will be initiated after a posting of payment is made to the card used at the point of boarding. The pre-authorised amount is reflected as the earmarked amount on your card and will be released based on the respective Issuing Banks’ policy.

    For Visa contactless bank cardholders, the daily accumulated fares will be earmarked at the end of the day, and released three (3) days later when it is posted to the banks. The posted amount may vary slightly from the earmarked amount due to transactions which were received within these three (3) days.
Commuter Assistance
  1. Who can assist me if I encounter problems at the point of boarding or alighting?

    Commuters who face issues at the point of boarding and alighting can approach the officers at the Passenger Service Centre (PSC) or Bus Captains for assistance.

    For error message on “entry/entry mismatch”, please approach the PSC for assistance.

    For all other error messages, please contact your Issuing Bank.
