Understandably, your TNG Card is DORMANT, so you need a new one. You got 7 days to get a new one but don't kanchong, Link your TNG Card to your e-Wallet and money will be deducted from there. Then once you reach JB, GO GET A NEW ONE AND TOPUP. This is for your ROADCHARGE! All Tolls now use E-Wallet money, and your Singapore based Debit Cards can be used in the wallet.
Check your card status by clicking TOLL button on the app and if your card is INACTIVE- means you are screwed, New Card is needed. Otherwise, you may be able to get a refund if you registered it on the TNG Portal.
YOU STILL NEED VALUE IN YOUR CARD FOR ROAD CHARGE!
That is similar to Trace Together in Malaysia. You can either use your IC Number as ID or Passport Number but I suggest you use your Singapore NRIC for that as your IC don't change.
Register using your Singapore Number and then register your overseas vaccination cert on the HelpDesk.
One trick is for your kids to be placed in your account, so one check in, all checked in.
Vaccination Process update was covered before.
It takes 5 days to update! Bring your ORIGINAL Digital Cert!
As Malaysia tend to cock up, please keep paper printouts so you cover yourself.
Do not forget , their ATMS close at 11pm-6am!
