 Somehow, skimming devices were installed at store checkouts in Felton and Georgetown during June. Both were Dollar Generals. Such devices can steal PIN numbers and account information if they're not caught. Police in each town are investigating and have urged consumers to carefully review their accounts for possible fraud. That's sensible advice anytime. When making a credit or debit card purchase, it's also a good idea to inspect the terminal for anything that just doesn't look right. If something seems amiss, it's best to move on.
