When making local bank transfers via FAST (e.g. rent), I see my DBS Altitude credit card as a source of funds – is it really possible to use my card for this, and will I earn miles on the transfer?

I've been using my DBS Multiplier savings account as the source of funds so far, and want to know if I've stupidly been leaving precious miles on the table. I'm just a little scared to experiment 😅

Unfortunately, I can't use CardUp/RentHero anymore, because my landlord insists on using a silly third-party/middle-man payment service (which requires me to make bank transfers via a specific link) 😒
