First post after being hooked on hak5 videos, I figured I'd bring this question I've always been wondering about to this place. I wont ask
"how to" because of the nature of the issue.
# I've been thinking for a long time how ownage it would be to utilize a card writer on (member benefits cards) my main example is at a local food spot called "subway". Every time you buy a sub you give them your card and it will load "points" on it based on the dollar denomination you spend at the point of sale. $1 = 1pt. 75pts for a "free" foot long sub (yum)
1) Is it possible to utilize a card writer to modify the amount of points on the card for more free yummage?
2) Would this sort of thing be simple?
===========================================
## Where I am there is also a local bus transit system that gives you (paper based) change cards sort of like NYC metro cards.
1) Would it be possible to carry out the same sort of system above on a card like this for more free transportation?
===========================================
Thank you in advance for your input
