Hi renfred,
Saw your post in the apple pay forum saying that you can add the MasterCard registered in ABT under the transit portion in samsung pay. Can share how you do it? I'm currently using nfc sim also. Don't see the option to add the MasterCard into the transit section.
Thanks.
You can visit the apple forum for more details on the registration and setting up of mobile wallet on ABT portal. I shall not share more in this section to avoid confusion, since this is still a trial phase with limited users.
To answer your question, so long the mobile device is registered successfully, samsung pay should have a section for you to choose, "select payment card", then it will prompt you to select default NFC option, which you should choose android operating system, then samsung pay will take over the transit portion for tap and go without authentication.
Currently, samsung pay for nfc ezlink sim card offers a platform for you to see the details, but does not interfere with payment. meaning with or without samsung pay, you still can tap the nfc ezlink sim card.
