VIALET doesn't support following merchants:
- Automated petrol stations
- Tolls roads
Such restrictions are in place per various reasons:
- Some merchants do not accept prepaid cards.
As a prepaid card, VIALET card requires merchants to seek online electronic authorisation before taking payment to ensure that transactions only go through when there’s enough balance on the card.
- Some gas stations and toll road booths are not pre-authorizing the exact amount of the transaction. Instead, they block a security deposit when you first use your card. While it is usually reversed back to your account after few days, in some cases this can take a longer period of time.
You can always pay for these services when they are manned/not automated.
