They are two different things. You can get rewards points from using the BPS credit card, or you can get reward points from using the reward card.
When I called the customer service number they told me that on the reward card, the points were cancelled after one year of inactivity. If you have points on both the credit card and the reward card, and you haven't used the reward card in the last year you loose the points. I don't have a credit card so I didn't ask about it.
