Written Reply to Parliamentary Question on Reconciling Payments for Transport Fares Made on Same Credit Card but via Different Platforms

Ms Yeo Wan Ling asked the Minister for Transport 

a.     whether the EZ-Link system will be enhanced so that records of payment made from different mobile devices like watches and phones linked to the same credit card can be reconciled to aid ticket inspectors’ verification of a commuter’s payment; and 

b.     if so, when.

Reply by Minister for Transport Chee Hong Tat:

1.     The digital identifier of each device used to make payment is different, even if they are linked to the same bank card. For security reasons, the links between identifiers and cards are only known to the issuing bank, and vendors such as SimplyGo are unable to automatically link different payment devices or cards. Commuters are encouraged to produce the device used to tap in when requested by our Ticket Inspectors.
