While trying to buy stuff online with a credit card, the options available are usually restricted to Visa, MasterCard and AMEX. I am thinking of getting a credit card from Chase, but where could I actually use it? I am in Toronto, Canada, and I don't remember seeing any restaurant or grocery store that accepts Chase cards.
If you read the fine print in the Pricing & Terms section of that card, you'll see:
By becoming a Visa Business Card cardmember, you agree that the card is being used only for business purposes and that the card is being issued to a public or private company including a sole proprietor or employees or contractors of an organization.
So that card is a Chase-branded Visa card, and should be accepted anywhere other Visa cards are.
Credit cards are normally either MasterCard or Visa, although many of them make that rather inconspicuous. The only major exceptions I know of are American Express and Discover. (And store cards that are only good at one particular store.)
