I just finished reading an article in Consumer Reports, June 2011, Page 25. They rated the anti reading devices and found that most will protect some information, but will not completely protect all cards. A staff member used aluminum foil, wrapped with duct tape. "Our reporter offered her own homemade shield constructed of duct tape and lined with aluminum foil. It provided better protection than eight of the 10 commercial products, including a stainless-steel RFID blocking wallet selling online for about $60."
This activity comes after opening my card statement yesterday and finding a charge of $312 to a local grocery store. I immediately contacted the card company and was advised to return to the store to obtain a copy of the receipt. In addition to confirming it was not my purchase, the store's security film was reviewed by the manager and he reported that this was a fraudulent charge and definitely not me. I contacted the local police and filed a report. I'm dropping off a confirmation letter from the card company to the police department today, along with a copy of the receipt.
This will be my third time, since retiring and moving to a town about 20 miles from a resort area two years ago, that I've had an issue with credit card information theft. I made my aluminum/duct tape barrier this morning and have wrapped my cards. I went online to purchase a RFID wallet, but found that the prices were all over the place! How does one know that they're purchasing a viable product? Rather than waste my money, I decided to peruse information supplied by the trusted Consumer Reports.
It's interesting to note that I worked in the ghettoes of Baltimore City for almost 20 years as a firefighter/paramedic and never had an issue with credit card fraud/theft. I moved to a small town, outside a large resort area and have had three fraud/theft issues within two years! Be especially careful with your cards when visiting beach areas!
