Will my Indian debit card work in the U.S.?
Whether your card will work, I believe, depends on the institution that issued it. You'll just have to try. What I can tell you, is that the process of using a debit card or credit card in the US is fairly straight forward. If your card has a chip, you'll 'insert' your card, chip end first, into the bottom slot of the reader, assuming the reader has one. This technology is still being distributed / accepted, so you may encounter some areas where they don't have this, or they have an insert or sign that says something along the lines of 'No chip reader / swipe instead'. If your card doesn't have a chip, which looks like the bottom end of a cellular phone's SIM card, you just swipe your card in the reader. There will / may be on-screen prompts, which will explain any additional input necessary from you. Depending on how they 'process' your card - As a debit card or credit card (They can 'process' a debit card as if it's a standard credit card), you may or may not be asked to enter your debit card's PIN. If they process it as debit, you'll have to enter your PIN. If they process it as if it were a credit card, it will still go through but you'll be asked to sign the receipt.  IMPORTANT FOR YOU TO NOTE: You need to find out whether your card issuer will charge you foreign transaction fees when you use your Indian debit card in the US.  Is the card carrying a different currency than the US?
