My 13-year old cousin who just graduated from 8th grade is going to Australia for 16 days. His mom wonders if he'll have any trouble using a debit or credit card that doesn't have the smart chip technology. I have found a few articles that seem to indicate that Australia is further along in adopting the smart card technology than the US, but nothing that clearly says that he won't be able to use a magnetic stripe card. Would Visa or Mastercard be better? He's traveling with about 40 of his schoolmates and it sounds like they're going to have a great time.
