      Although this seems suspicious to me (it's hard to believe that as highly-motivated a work force as the desk personnel at a hotel won't slip up and forget from time to time), I guess it's true that the keys are then kept in a reasonably safe place until they are re-encoded for the next visitor. (Is this true? Is there a way to recover old information from a magnetic stripe even after it's been overwritten?)

        I know a lot of people (including myself, until now) simply assumed the card had some magick code on it that opened the door, and once they checked out, the code stopped working, so key cards got:

        1) left in the room when you walked out. There's probably a box on the cleaning carts where they get chucked. Highly insecure.

        2) left in the rental car or wherever. You're done with it and presumably it has no information relevant to you.

        3) idly thrown away (probably the most secure, provided its a sufficiently yucky trash can)

        4) Taped to office doors or cube walls to make a "gee, I travel a lot" mosaic.

        The idea that they're somehow secure because they MIGHT get stored and reused seems laughable.
    • they DO erase them after you check out, don't they?

      I'd be willing to bet that most of them simply put them back on the stack behind the front desk, to be overwritten if and when they get reused. This, of course, raises another interesting question - can the information of prior users of the card be obtained with data recovery techniques? How many generations of data could one conceivably extract from a single keycard?

        Using a regular card reader I'm pretty confident you could only get one "generation." To get the next one you'd have to use some pretty specialized equipment. And I'm not sure it would be a sure thing either, provided that the information was recorded into the stripe using the same equipment and the same power level.

        However if the hotel personnel sometimes used card reader/writer A, which has low power, but occasionally reader B, which has an ever so slightly higher power level, then assuming the last one used was A, you ought to be able to get at least 2 records off of the card, because the last record from B will be buried a little deeper in the strip than the overwrite by A.

        Or if you had 3 card reader/writers, each at slightly different power levels, and used them in the right order, you might be able to reconstruct 3 sets of data from the card.

        The analogy I'm thinking of is like how (analog) HiFi audio is written to a VHS tape [eed.usv.ro]: it's recorded onto the tape underneath the video signal, using a recording head where the flux pattern goes deeper into the recording medium. (It's also separated by virtue of an FM carrier and the azimuth angle of the recording heads, which you wouldn't have on a magnetic stripe card.)

        I've read some articles on recovering overwritten information from linear magnetic tape (Nixon tapes, etc.) and it's no easy task. The usual way to do it is to just look for areas of the tape near the edges that weren't saturated by the erase head the second time around. I'm fairly confident in saying that recovery of two sets of data, made by the same reader/writer, would be non-trivial.

        Aha... here's the email I heard this from:

        From the Colorado Bureau of Investigation:

        "Southern California law enforcement professionals assigned to detect new threats to personal security issues, recently discovered what type of information is embedded in the credit card type hotel room keys used throughout the industry.

        Although room keys differ from hotel to hotel, a key obtained from the "Double Tree" chain that was being used for a regional Identity Theft Presentation was found to contain the following the information:

        a.. Customers (your) name b.. Customers partial home address c.. Hotel room number d.. Check in date and check out date e.. Customer's (your) credit card number and expiration date!

        When you turn them in to the front desk your personal information is there for any employee to access by simply scanning the card in the hotel scanner. An employee can take a hand full of cards home and using a scanning device, access the information onto a laptop computer and go shopping at your expense.

        Simply put, hotels do not erase the information on these cards until an employee re-issues the card to the next hotel guest. At that time, the new guest's information is electronically "overwritten" on the card and the previous guest's information is erased in the overwriting process. But until the card is rewritten for the next guest, it usually is kept in a drawer at the front desk with YOUR INFORMATION ON IT!!!!

        The bottom line is: Keep the cards, take them home with you, or destroy them. NEVER leave them behind in the room or room wastebasket, and NEVER turn them in to the front desk when you check out of a room. They will not charge you for the card (it's illegal) and you'll be sure you are not leaving a lot of valuable personal information on it that could be easily lifted off with any simple scanning device card reader. For the same reason, if you arrive at the airport and discover you still have the card key in your pocket, do not toss it in an airport trash basket. Take it home and destroy it by cutting it up, especially through the electronic information strip!

      Let's have a reality check here.

      First, I want to say that I've worked at a hotel (night auditor/clerk). We had a VingCard system when I was there and at no point did any personal information hit these cards. I know people who work at hotels with slightly more advanced systems, and none of them store any personal information. They just store the room and duration.

      I won't say that such cards with personal information don't exist. I will say that they aren't the norm. Let's look at this from a realistic standpoint though:

      • If your hotel doesn't allow you to use your card to charge things to your account then you probably have nothing to worry about. Why would they include any personal information if you can't use that card for anything but entry to the building and your room?
      • Even if your hotel does allow this, what benefit do they gain from having your information (more than your room) on the card? Obviously the payment system must be hooked into the registry somehow, so why wouldn't they just store the room number/unique id to make the link? Wouldn't it be MORE work for them to link it back if they use your information instead of theirs?
      • Let us say that these cards are in a lot of places, why are we worried about them when folios are normally plain text and stored in paper format somewhere on the premises? You don't know what happens to these records. Normally they just get locked in a storage closet for a while until they get thrown out.
      • I hope you don't ever buy anything online. I'd venture to guess that it's much more common for poor security practices to be used on billing databases for e-comm than it is for hotels to embed your billing info on your keycard. For that matter, if you have a CC you probably use it all over the place. The receipts are normally poorly handled and not very secure. Point being that your CC information is rarely secure, and that includes places that also get your address.

      This seems like much ado about nothing. It's a fairly low risk scenario when compared to all the other ways to get at this information. Who's going to sit around at these hotels and swipe cards looking for embedded information? If they did, don't you think the CC companies would eventually catch onto how it was happening, or at least that it was just a few hotels?

      I'd ask how my information was being shared if they said that I could use my keycard to pay for things. If there's nothing like that, I wouldn't worry about it. Depending on the situation, I might keep the card. Normally I just turn it into the clerk, who has access to all the information on it anyway.

      If you do keep your card, perhaps you should consider keeping it under your tinfoil hat.

    I've worked in a number of hotels for the past seven years- and all of them used electronic key systems, either the card type, or an electronic microchip key.

    In EVERY case, the key system is a seperate box not tied into the main computer, and only contains your room number, and length of your stay. The device is ONLY a key coder - it does not tie-in to the main network or the hotel's database in any way.

    This story is spreading FUD, do we really need more of that going around?

    Instead of using a hotel keycard, they should code the lock to allow you to open your door with your own credit card. That's something you're far more likely to take good care of, and then you don't have to worry about duplicates of that information floating around.
  • I don't see the point in putting all that information on the card in the first place. All the card has to do is match the embedded code with the code the door is programmed to accept. Why bother with anything else?

    A metal key doesn't need all that extra information, and is somewhat harder to duplicate. By that I mean all you need is a card reader/writer and a blank card. The card doesn't need to be a specific shape, they are all pretty generic, aren't they? A metal key in comparison is secured not onl
    • If you lose a metal key you'll have to re-key the lock to prevent the "finder" from getting inside. It's also harder to make an instant replacement for the customer.

      With the keycards, you can simply change the door code and generate fresh cards. I agree though, putting anything other than a pointer or key value on the card is just asking for trouble.

    Sure it's possible to put any kind of data you want on a magnetic strip, but you might as well worry the hotel is printing your PII data on sheets of paper and tossing them out the back windows. What possibly reason would they have to put info like that on the keycard??

    The key cards at hotels don't hold anything but the room number and number of nights it needs to work.

    My hotel keycard has the little logo graphic of the hotel on the front of it and a memory storage device on the back. There's also a small mustard stain on it. What kind of data is stored within the memory on the card is an entirely different thing.

    To quote George Carlin:

    Really. Despite the fact that this has already been identified as a probable urban legend by Snopes, I ask everyone on this site to think of this like an engineer.

    Think about this. You're designing an electronic key-card system for a hotel. In order to do this you have to deal with lobby-monkeys who only occasionally swipe the card correctly through the machine when the customer's checking in. These cards are going to get shoved in pockets, scratched and generally abused.

    Now, as an engineer are you going to create a solution that (a) writes to the magnetic strip for every person who checks into the hotel, running the risk that the card runs through skewed or otherwise renders the information unusable, or (b) are you going to assign each card a unique ID number similar to a credit card number that's permanently printed on the card repeatedly across the magnetic strip.

    Talk amongst yourselves, but think about the fact that a mag-stripe WRITER costs more than a mag-stripe READER. If you control the locks from a central computer which only has to recognize that card (a) opens door (z), then how are you going to engineer that system for optimum efficiency and lowest cost?

    While I don't doubt some droid might consider it a nice idea to have all the customer's info on the card, it doesn't make an awful lot of sense from an engineering perspective now, does it?

    And yes, I've worked on hotel key card systems, and no I've never seen one that writes the cards in any way shape or form on check in.
