Many credit unions have card readers to control access to their ATM vestibules. There has been a recent string of attacks on these card readers by fraud artists attempting to skim debit cards. An overlay is placed on the entry door card reader so that information can be taken off of the magnetic stripe when the member attempts to gain entry to the vestibule. A pinhole camera is installed on the ATM itself in order to capture the accompanying PIN.
Criminals have had a lot of success with this method of skimming cards, so credit unions are advised to carefully consider whether the benefits outweigh the risks of maintaining card readers on their ATM vestibule doors. Please keep in mind that if the banks have removed these devices, we could see a dramatic increase in the number of attempts at credit unions.
