Topping store value.
Not everyone goes to the bus interchange or MRT stations.
One morning sent my bike to workshop, then took bus home.
Alighting at my place, I saw that the balance was well into the
negative. Later need to go to work, and no value in the ez-link
card. Only have one card, no standby card, like previous
TransLink card. Luckily I have enough small change, to pay cash to
go to work, and then top up at 7-11 near my work place.
That was also the day, I found out ATMs do top up ezLink
cards.
