TidBITS has published Security Tips for Safe Online Holiday Shopping, a brief article discussing some of the basics of making sure you don’t get any surprises from your on-line purchases. Rich Mogull discusses how to use “new payment options”, such as one-time credit card numbers, and gives advice on using a credit card or PayPal account for Christmas purchases. He then discusses “e-mail fraud”, or phishing, though that’s not specifically related to holiday shopping. And he finishes the article with a few tips on protecting your web browser. While most of the tips here are common-sense, it’s always a good idea to remind yourself that it’s not always safe to purchase things on the Internet.
