Saving money vie ez-link card

If transfer can actually save money as compared to single trip, then,

2 people work in shifts. One starts work at 8am, the other ends work at 8am.
Both of them work in the same factory or very near each other, and
both of them live together or very near each other.

Say if one takes an ez-link card and goes to work, then pass the card to the other person who is coming back from work. Effectively, that would make a transfer tripon a single card , instead of 2 individual ez-link card which would not have any saving at all.

Should that transfer save 10cents, then for a 5 day week, it would be about 0.1x5x4=$2 saved.
