when u board a bus, u tap it like any ez-link card. the special
thing, no fare is deducted - it jus shows "PASS USAGE", even if u
have $0.00 in ur card. same thing with MRT, except it shows
something like "RIDES LEFT 3". all ur rides will be free in that
month, unlimited for bus and 4 rides a day for MRT/LRT/NEL.
for final yr students, the decision is solely dependent on whether
u need the pass to save on ur transport costs. unless u stay very
near (spend up to $0.84 for a single trip from home to sch),
getting a bus/train/hybrid pass will save any tertiary student a
lot of money. even if i can only use it for a month, i'd gladly
take it, needless to say for 12 months.
ur concession card can still function as a normal adult ez-link
card after u've graduated. of cos, the difference is only the fact
that ur face is on it, and if u lost ur card u can get back the
last balance recorded on the ez-link system and disable the card
with ur I/C at any TransitLink office.
