Just saw these posters plastered all over the Uni ("pre" O-week). Poster came with a tear-off tag with the promo code.
The poster claims that you can purchase an uncharged BoPo Prepaid VISA card (normal value $14.95) for free using the promo code.
Might be useful for internet purchases if you don't want to use Paypal? Plus they're rechargable and look pretty cool =)
Biggest show-stopper for bopo — fees!!

Recharging your card costs $1. Buying things online/offline costs you $$. transfer between cards costs you $$ and you have to do it because if your old card expires, it costs you $5/month!
Some banks offer annual-fee waived credit card to uni students with very low credit limit ($500?)
