Are PINs always needed for paying with card?
There generally isn't much in the way of real identity verification, at least in the US and online.  The protection you get is that with most credit cards you can report your card stolen (within some amount of time) and the fraudulent charges dropped. The merchant is the one that usually ends up paying for it if it gets charged back so it's usually in the merchant's best interest to do verification.  However the cost of doing so (inconvenience to the customer, or if it's an impulse buy, giving them more time to change their mind, etc) is often greater than the occasional fraudulent charge so they usually don't do too much about it unless they're in a business where it's a frequent problem. As far as I'm aware, PINs are only used for in-person transactions, not 'remote' (over the Internet or phone). "For the first part of your question; Refer to related question  Why do some online stores not ask for the 3-digit code on the back of my credit card? The other case of Airport ticket machines, requires the physical presence of card. The assumption is that if you had the card before and after the transaction, it was you who used it for transaction. As the amounts are small its really easy by anyone [merchant, Banks] to write this off. The only way to misuse would be if you lost the card and someone used it. Also these ticket machines would have built in feature where by you cannot buy more than ""X"" tickets for the day. Ensuring max loss on a stolen card is limited to a small amount." Chip and Pin cards are popular in Europe, however in the US we don't have them.  Visa/MC and Amex can issue chip and pin cards but no merchants or machines are set up here to take them.  Only certain countries in Europe use them and since you could possibly have a US visitor or a non-chip and pin person using your machine or eating at your restaurant they usually allow you to sign or just omit the pin if the card doesn't have a chip. It is definitely less secure, but the entire credit card industry in the US is running right now without it, so I don't think the major credit card companies care too much (they just pass the fraud on to the merchants anyway). Security in the merchant services system is mainly handled in two ways: 1) Before transactions are done, the business itself must go through an application process similar (but not identical) to getting a loan.  Some high risk businesses must pay higher fees due to the increased likelihood of customer complaints. 2) When a customer disputes a transaction, that's a mark against the business.  Get too many of these disputes, and your priviledge of accepting credit cards will be revoked, meaning you won't be able to again. It's in the merchant's best interest to verify customer's identity, because disputes cost them money directly.  It's in the servicer's best interest to verify the businesses integrity, because fraud drives up the cost for everyone else. As a whole, it's quite a reactionary system, yet in practice it works remarkably well. Like email and spam, fighting creditcard fraud is a cat and mouse game, with technology and processes constantly being developed to reduce fraud. The CVV on the back of the card is just one more layer of security.  Requiring the CVV generally requires you to physically have access to the card. CVV should not be stored by any merchant. This frustrates card skimming fraud as the CVV is not present in the track data and fraud caused by database compromises.  You should never use your PIN online. MC/VISA both have implementations of 3D-Secure (SecureCode for MC and Verified by VISA) which require a password / code to confirm card ownership. Depends on both Issuer and Merchant implementing the standard.  Regarding not needing a PIN at the airport, some low value transactions no longer need PINs, depending on the Issuer and Scheme (VISA/MC). MasterCard PayPass or VISA PayWave enable low value contactless transactions without PIN. In Australia, the maximum value for a contactless transactions is $100 AUD. At some merchants (McDonalds for example) a PIN is not required for for meals purchased with VISA (at least, for the cheeseburger I bought there as a test). This makes sense - if you don't need a PIN for a contactless purchase, why do you need it for a chip based purchase?  So - why allow PIN free transactions? On average customers report stolen credit cards / wallet very quickly and the losses are correspondingly small. As card issuers are always online, cards can be cancelled very quickly after being reported lost / stolen. Finally, by performing transactions for just a few cents or pennies, the merchant (Spotify) can likely validate you are the owner of the card as you'd need access to your online bank to confirm the transactions.  PayPal do this with bank account to confirm ownership. (Unless I've misunderstood your statement).
If your goal is to make it harder for you to use to make impulse purchases then YES.  Having to always have cash for purchases will make you less likely to make impulse purchases you don't really need. "Interesting; England went ""chip &amp; PIN"" years ago and Australia went ""chip &amp; PIN"" today but I've never heard of EMV. I had to look it up to know what it was.  The point of the switch is to reduce fraudulent transactions. The chip can't be copied as easily as the strip.  That's all I know. Rally I just replied because I had not heard of EMV." There are numerous reasons that go beyond the immediate requirement for access to credit.  Many people just plain don't like carrying cash. Before electronic debit cards became mainstream about the only way to pay for online services was with a credit card.  This has now changed just about everywhere except a large number of airlines which still only sell online tickets via a credit card payment. And then there are all those countries where governments (and some banks) have decided to charge merchants more when customers use debit cards.  If you don't like carrying cash then you may find that the only card you can use is a credit card. These concerns are gradually disappearing and at some stage someone is likely to offer a combined debit-credit card. At which point you'll probably get credit whether you like it or not. I haven't had a credit card in fifteen years. I use nothing but my debit card. (I find the whole idea of credit on a micro scale loathsome.) I have yet to encounter a single problem doing so, other than a lower than usual credit score for not keeping 23(!!!) revolving lines of credit open, or that's the number CreditKarma tells me I need in order to be an optimal consumer. In an nutshell, no, you don't NEED one. There are reasons to have them, but no. Payment processors get a fee when you make a payment through their system. So by encouraging you to use their cards more, they make more money. In the specific case of contactless cards, they see an opportunity to grow their market by displacing cash payments. So they're advertising it heavily to help that along. ACH, Paypal, Amazon Pay are all other options that can be used.  ACH is cheapest for the merchant but it is a bit of a pain for the customer to setup (aka adds friction to our sales process, which is *very* bad).  Paypal and Amazon Pay both cost a bit more than regular credit cards for the merchant.  Google Wallet is free but not available unless you are a sole proprietor or an individual, which is is useless for businesses.  So yeah, other options are either difficult or more expensive. I've never forgotten mine either, but it's a constant fear for me. Couple of friends of mine have. I honestly don't know which machines beep and which don't, but I've heard of people forgetting their cards in ATMs, cigarette vending machines, train ticket machines, McDonald's express order machines and some others I can't remember. The screen of these machines always reminds you, and I think it's hard to forget it, but evidently it does happen.   I still use my cards, it's not like I have a crippling fear every time I use it, I just made a habit of always carrying cash and using it for small stuff. I live in Germany, cash is (still?) Accepted everywhere. Update, 2013: this product is no longer available. As of December 1, 2010, Travelex announced a product, the Travelex Cash Passport, which is chip-and-pin protected. You can buy it in the US and then load it up with either Euros or British Pounds. There are a few things to know about this: Right now, it is not available online at the Travelex website. You must purchase it in person at participating Travelex retail locations. I bought mine right downstairs from the Stack Overflow world headquarters! The fees that Travelex charges for foreign currency transactions will take your breath away. I purchased a £300 card for $547.15, which comes out to a 15% service charge. Travelex will give you better rates if you purchase larger amounts. There is a further 3% fee if you use a credit card (I used a debit card to avoid this). Think long and hard about whether to load it with Pounds or Euros. They charged me 5.5% above the interbank exchange rate to spend my Pound card in Euros. You get two cards, which is very convenient. You can refill the card on the web. Due to the high fees, the Chip and PIN Cash Passport is not a good idea for everyday transactions, for getting cash from an ATM, and certainly not for paying for big-ticket items like hotels. You're going to want to reserve it for purchasing things from those automated kiosks in Europe (especially gas stations, ticket machines in train stations, and toll booths) that will not work with a standard magnetic stripe card. The card worked perfectly buying tickets on the tube in London. I haven't had a chance to check it out in other countries. Yes, retail stores will let you use multiple cards to make a purchase. Just be sure to know the exact balance on each one and tell the cashier how much you'd like to put on each card. If you don't know the balance and try to charge more than what is available, your card will be declined. While in the UK and travelling to Europe, I heard of the FairFX euro card from the website Money Supermarket (affiliate link which waives the sign-up fee). The link also includes many other alternative prepaid euro cards which may be better suited for your uses.  The FairFX card is available in both GBP and EUR, and both products come with chip and pin. They also charge relatively little as compared to most bank cards (no currency conversion on use, $2~ withdrawal charges from ATM).  I generally had a good experience with this card, and was able to purchase items both in person as well as online using it. It depends on your bank and your terms of service, but using the card one way or the other may affect things such as how long it takes to process, what buyer protections you have, etc.  It also affects the store as I believe they are charged differently for debit vs credit transactions. I use cash exclusively. I go to the cash machine once a week and withdraw the money I want to spend in one week (so I have to plan if I want to buy something expensive). Otherwise I leave the card at home. As bonus you get anonymity, i.e. big brother cannot track you. "When using a debit card in a ""credit"" way, you don't need to enter your PIN, which protects you from skimmers and similar nastiness. Also, assuming it's a Visa or Mastercard debit card, you now have access to all of the fraud protection and other things that you would get with a credit card. The downside for the merchant is that credit card transaction fees are typically higher than debit card transaction fees. I'm less familiar with using a credit card in a ""debit"" way, so don't have anything to offer on that part of your question." &gt;&gt; Hey! Do you mind giving your credit card to the waiter...  &gt; I'm not especially fond of that, but it's easy to report fraud to the bank and most of the time the bank will reverse the charges.  No kidding! Of course, even I give credit cards to waiters. What do I care? **As you said, you are not liable to any fraud on your credit card.** None at all!!!!  It's only Merchant, not the credit card company, that pay the price for fraud... **and you pay higher prices to cover for losses from fraud.**  &gt; The PIN situation is different because a mugging is life-threatening.  Nonsense! Mugging at the ATM is so rare, each ATM has a camera. **In any case, I am not talking about using PIN to withdraw money!** I am talking about PIN to authorize charges on a credit card or ATM card.  &gt;&gt; We already determined that nobody even care about signatures or check them.  &gt; You can't use a stolen card at an ATM with a signature.  Huh? You totally got it wrong what I said, or, you argue for the sake of argument.  **I am saying that cards that require you to enter a PIN cannot be used used when stolen or copied. Yes or no?**  **On the other hand, cards that require signature can be used when stolen or copied because signature is a worthless method to validate the charge. Yes or no?**  LASTLY, my Costco credit card has a picture of me on it. **Question for you, since for some reason you argue so much against PINs: Wouldn't a picture on the card better than a signature?** Yes or no?  Do you see? There are so many ways to make this system so much more secure and fraud proof... but, ON PURPOSE, the credit card companies don't want that... because they are not liable for fraud. Simple as that. Yes, there are a bunch. I have used Paypal and it worked quite nicely. I see endless ads these days for Square, a tiny card reader that you plug into a smartphone that lets you swipe the card. (With Paypal you have to type in the credit card number.)
