What's On Your Hotel Keycard 416
Lam1969 writes "From Robert Mitchell's blog on Computerworld: '... Wallace, IT director at AAA Reading-Berks in Wyomissing, Penn. has been bringing a card reader with him on business trips to see what's on the magnetic strips of his hotel room access cards. To his dismay, a surprising number have contained his name and credit card information - and in unencrypted form.' " Update: 09/20 19:10 GMT by J : Snopes, as of two months ago, says this is false.

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.

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?
Data Recovery (Score:5, Insightful)
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.

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!

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:
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.

4. The Snopes article quotes a security expert who tested 6 cards at a security conference. 3 contained personal information, including one with a credit card number.
My experience at Walt Disney World is that the room key can be used in a credit card swiper and charges the card used to reserve the room. I still have this key card. If I ever get a stripe reader, I'll check.
The point of the Snopes article isn't that you will never find a CC number on a key card. The point is that they are not aware of this as an ACTUAL security threat. There's no reason that can't change in the near future, of course.

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?
