From the usability testing I did before, I found that the participants were not really comfortable of showing their credits in the first place
User Interface Design #1: T-Wallet
Satrya Rudana

Hmmm interesting result, Since I did couple UT as well for 3diffrents eWallet/Payment apps, I always found almost same result that user wanna know how much balance they have, maybe in not too subtle way but clearly shown at the first glance,

If put it behind like this, they need to go-back andnforth before make payment just to make sure they have enuf balance.
