Your card is certainly eligible for cash back rewards. It is not exactly
$1 back for every $100 spent however.
Every $100 you spend on your card earns you 1 point. On the card's
anniversary date, once a year, your points will be paid back to you in
cash. If you have spent between $2000 and $8000 on your card within the
year, you receive 50 cents back per point. If you have spent greater
than $8000 on the card within the year, you receive $1 back per point.
The maximum cash back you can receive in 1 year is $300, and you receive
this if you have spent $30,000 or greater on the card.
