What Can Be Done About Security of Debit Cards?

JumpDrive writes "I have been the victim of (Visa) debit card theft. I do not know where they stole or got the number, but it was used one day on the other side of the country and the next day it was used in Europe until they cleaned out my account. I had been monitoring my account online and immediately went to the bank and filed a claim. I was told at that time it would be 3 to 5 weeks for them to investigate the claim before they could return my money. Recently I tried to make a purchase with a debit card and was told that they couldn't use the card since it wasn't a Visa or MasterCard check card; this led to a discussion of why I no longer have a Visa or MasterCard check card. Which then led to the question of 'What can be done about it?' Currently I have a separate account for debit usage for my personal safety. But I also think that those producing these check cards should be required to advertise the hazards of having one of these cards (not in small print and maybe required in advertisement of these cards, similar to what is required with pharmaceutical drugs on television) and/or that if a debit or check card is issued a separate account should be required for its use, and users informed of the issues of placing all of their money in the same account that their debit card has access to. What other precautionary measures should be required or taken?"

    The short answer? The banks will do nothing for you today.

    The long answer: Nobody will do anything for you tomorrow, either.

    Why? Because Visa does two things, only one of which makes money. First, they are in charge of defining financial card security through the PCI council, and they own and operate the secure network VisaNet, which carries authorizations from retailers to banks. Guess which one makes them money?

    If Visa were to design and offer a cryptographically secure solution, one based only on smart cards for the customers and Hardware Security Modules (HSMs) at the banks, then I could safely route my charge authorizations over the plain ol' Internet. I wouldn't need to use the charge-per-transaction VisaNet. Visa would stop making money.

    So instead of offering a secure solution, Visa and the PCI council say, "Merchants must lock down their systems, protect this data, follow these 12 steps, acknowledge that you are powerless over alcohol (oh wait, wrong 12 steps), and if you don't, we'll loudly blame you for allowing someone to see our non-existent security."

    Visa owns the protocols used between merchants and banks. They could strengthen the protocols. They could prescribe encryption. They could require the deployment of chipped banking cards. But they do not, and have not for many, many years, despite a pathetic track record of security.

    If you want the banks to be safe with your money, you ironically have to take charge of your own security. If you switch to using the green paper stuff, your losses will be finitely limited to what you carry on your person. If you want a more achievable answer in today's plastic world, DO NOT CARRY DEBIT CARDS. Debit cards do not offer you protection against loss. Credit cards are limited by U.S. law to a maximum of $50 liability to the cardholder. Debit cards losses are usually covered by the bank, but they are under no legal obligation to do so. For ATM access, most banks will honor your request for an ATM-only card instead of accepting their default ATM/Debit card. Of course, the use of credit cards requires personal discipline to always pay the debt on time, but otherwise you would see little difference.

      (Emphasis mine).

      Actually, I don't think the part about the lack of debit card consumer protections is factually accurate. Here's the blurb from The FTC's Facts for Consumers:

      ATM or Debit Card Loss or Fraudulent Transfers (EFTA). Your liability under federal law for unauthorized use of your ATM or debit card depends on how quickly you report the loss. If you report an ATM or debit card missing before it's used without your permission, the EFTA says the card issuer cannot hold you responsible for any unauthorized transfers. If unauthorized use occurs before you report it, your liability under federal law depends on how quickly you report the loss.

      For example, if you report the loss within two business days after you realize your card is missing, you will not be responsible for more than $50 for unauthorized use. However, if you don't report the loss within two business days after you discover the loss, you could lose up to $500 because of an unauthorized transfer. You also risk unlimited loss if you fail to report an unauthorized transfer within 60 days after your bank statement containing unauthorized use is mailed to you. That means you could lose all the money in your bank account and the unused portion of your line of credit established for overdrafts. However, for unauthorized transfers involving only your debit card number (not the loss of the card), you are liable only for transfers that occur after 60 days following the mailing of your bank statement containing the unauthorized use and before you report the loss.

      If unauthorized transfers show up on your bank statement, report them to the card issuer as quickly as possible. Once you've reported the loss of your ATM or debit card, you cannot be held liable for additional unauthorized transfers that occur after that time.

It's not unreasonable for the consumer to have some burden of identifying the loss, since each of us are the best and most efficient judge as to whether or not the transactions on our accounts are in fact ones we performed. Millions of dollars in software development and analyst training have been spent on helping banks to detect fraud, but those systems aren't fail proof.

      Did I say RF? No, I said "chipped", although once the security is done correctly RF might not matter as much as you might think.

      The correct protocol is for the merchant to tally the merchandise, and present the customer's card with their merchant ID and the transaction amount. The cardholder then has to see and approve that amount by entering a PIN in order to generate an authorization. (The cardholder needs to enter that PIN into a trusted device, which is best met by a smart card with a built-in keyboard and tiny display, or alternately by a trusted keycard device issued by the bank.) The card uses the PIN to generate a one-time approval code, which is forwarded by any means to the bank, along with the card data (account number or whatever), the amount, and the merchant ID. The bank returns an approval code to the merchant, who gives the merchandise to the customer. All this is digitally signed, of course, and the protocols need to be well laid out to avoid potential problems with respect to money laundering, man in the middle attacks, etc.

      Note that the customer's account number is only usable for identification. It's only the chip-generated authorization combined with the user entered PIN that carries the value. Something you have plus something you know.

      The authorization data is carried by the merchant and delivered by whatever means to the bank. The Internet would work fine. The merchant can see your account number, but they cannot charge you anything other than the value included in your approval. The authorization code is accepted by the bank for one time only use, and they will pay only the merchant ID indicated in the transaction.

      Note that in this case, the card is issued by the bank. The certificates and keys are created and injected in the card by the bank. That means it's 100% bank-owned-and-provided hardware from customer to bank and back again. The bank is 100% in charge of security. All you have to do as a customer is not to lose your chipped card AND keep your PIN secret.

      An RF based card would make only a minor difference in security. Sure, someone could ping it, but they couldn't get it to emit an authorization token unless they had it in their hands and pushed the tiny buttons. Protections would have to be taken to prevent RF based man-in-the-middle attacks between the merchant and the customer's card, otherwise the merchant might not get paid. But the customer's money is never at risk except when they are entering their PIN, and are staring at the tiny screen that says "PAY WALMART AMT=$34.56".

      I work in bank security, and I just wanted to offer some clarification on your rant:

      If you want a more achievable answer in today's plastic world, DO NOT CARRY DEBIT CARDS. Debit cards do not offer you protection against loss.

      A debit card can be used in two ways. It can either be used with a PIN in what's commonly called a debit transaction (or at an ATM), or it can be used as a "credit" transaction and processed through the Visa or MasterCard network. There is little to no protection against loss for the former of these transaction types, except keeping your PIN secure. The "credit" style transaction, on the other hand, is protected by a zero liability guarantee (at least Visa cards... not sure about MasterCard). Yes, your bank account may get cleaned out (or depleted up to the daily spending limit of your debit card), and outstanding checks may bounce, and you may have a freeze on your account until it gets resolved. However, this zero liability guarantee means any transactions found to be fraudulent will be reimbursed by your bank. The bank then goes after the merchant that processed the transaction to recoup their own losses. If you have a good bank, they'll also refund your overdraft fees. Debit or ATM transactions, on the other hand, are not covered by the same guarantee, so having your card skimmed and PIN captured is far worse - UNLESS your bank offers a guarantee on these types of transactions as well.

      See http://usa.visa.com/personal/cards/debit/visa_check_cards_faq.html

      Credit cards are limited by U.S. law to a maximum of $50 liability to the cardholder. Debit cards losses are usually covered by the bank, but they are under no legal obligation to do so.

      Losses due to fraudulent transactions processed through the Visa network are actually covered by the merchant that accepted the transaction, not your bank. Your bank only covers "Debit"-style losses they agree to cover if they offer protection against Debit or ATM transactions, but that's not a standard program.

      For ATM access, most banks will honor your request for an ATM-only card instead of accepting their default ATM/Debit card.

      An ATM-only card means you will have to use ATMs more frequently, thereby potentially exposing yourself to skimmers, as well as use of your PIN in public. Since there's no zero-liability coverage with most banks for skimmed ATM transactions, you're putting your money at greater risk by doing this. Oh, and by the way, the skimmers have this one figured out too. You no longer have to worry about the shady looking person loitering near the ATM watching you enter your PIN. They install a tiny camera painted to match the fascia of the ATM, and they aim it at the keypad.
