yes pass usage
but when u tap out, they wil show 'pass usage and show the exact
amt left'
this is correct and actual.
but IF you didnt tap out, you approach a General Ticketing Machine
or those ATM-top-ups, you will find that your value is lower than
usual. but in fact it is NOT lower, its the same exact amt, only
tat you have to tap out during the next trans to get back the
'lost' amt..
a defect, but wun affect the $ in ur card/...
