Really depends on what bank you working for... usually with such high commision means it's super tough. Means the market already saturated with such card holders.

Here's the hard part:
1. usually people already have credit card and do not want to apply further. To them more cards means more debts. So convince them...

2. what's ur plus point in credit card?? never expire points? lots of installments benefits?? free for life??

3. you may sometimes get along with no sales at all for one whole week. (if it's ur part time job, then different story la)

If u got lots of frens who just grad and got a job, faster grab them
