Chip Cards FAQ –
What about when I shop online with a chip card?
The chip in the card offers no improvement in security when you’re using your credit card number to shop online. It will be the same as if the card were a magnetic stripe card. If you happen to have a small portable chip card reader, then the enhanced security could come into play, assuming the seller on the other end could accept that kind of data. An artist selling paintings or a small merchant using chip-reading technology provided by Square or another vendor would still need to read an actual chip card in person, even though the transaction would almost seem to be online.
Where can I use my chip card?
You can use your chip card anywhere cards are accepted. You can swipe your card just like you do today using the magnetic stripe on the back of the card, if a chip-activated terminal is not yet available. The terminal or the cashier will prompt you to insert and leave the card in the terminal until the transaction is complete if it’s activated for a chip.
Can I still use my card over the phone or online?
Absolutely. Your card will work over the phone and online just like it always has.
What if my chip card doesn’t work when I insert it into the chip terminal?
Some merchants may have chip terminals, but they may not yet be activated to accept chip cards. If you are unable to insert your chip card into a chip terminal, you can always swipe your card to complete the transaction. Most often, merchants that haven’t activated their terminals will block the chip slot.
How will I know whether to swipe my card or insert it?
Your card will always work either by swipe or insertion. The terminal or the cashier will prompt you to insert the card into the terminal if it’s activated for chip technology. If the terminal is not yet chip-activated, you can always swipe your card to complete the purchase.
