Not really because it's not well implemented yet.
It's possible to load up the mandiri app and use the phone to pay for toll at the e-toll gate but I'd rather not, too scared that I could drop the phone inadvertently (let alone snatching thieves). Since those e-toll, e-money, indomaret, etc cards all use NFC, I suppose the phone could be used to pay wherever those cards are accepted. For me, still too much trouble.
I do use the NFC function to check the balance on my e-toll card though. Very practical.
Curious to know if there are other more widespread NFC payment methods.
