I got this via the SAO list, it doesn't explicitly say that its happened on campus yet...
ASUW & RSOs:
Please be alert to the following scam:
Thieves are putting thin, clear, rigid plastic "sleeves" into the ATM card slot. When you insert your card, the machine cannot read the magnetic strip. So, it keeps asking you to re-enter your pin number. Meanwhile, someone behind you watches as you enter and re-enter your number. Eventually you give up, thinking the machine has captured your card, and walk away. The thieves then remove the plastic sleeve complete with card, and empty your account.
The way to avoid this is to run your finger along the card slot before you put your card in. The sleeve has a couple of tiny prongs that the thieves need to get it out of the slot, and you will be able to feel them. Law enforcement would like as many people as possible to be aware of this scam. So, please pass this information on to your friends and family and associates.
If you have any questions or other information to share, please contact the UWPD Crime Prevention Officer, Ginger Banyai-Riepl, by calling 543-9338 or emailing firstname.lastname@example.org.
