I have read and re-read all the reassurances that RFID-blocking devices are unnecessary, including one site that said there has "never" been a proven case of capture of the card number by someone nearby with a scanner. However, my contactless Visa card was hacked and used for 3 purchases ( all declined by the card provider), under circumstances that make me wonder about this.
This is a new Visa card, linked to an airline miles program,, that I got a few months ago specifically to earn miles in that program. I used it exclusively for large expenditures such as airline tickets and property tax, never for general online purchases or point of sale purchases. I did not carry it with me outside our home until a recent road trip. I brought it along then as I planned to purchase some airline tickets during the trip.
We left home on July 25 and our first stop was Boise to visit family. While there, we stopped by a Walgreens to pick up some needed items. My husband paid for the purchase with an unrelated card, while I stood nearby with my card in my small cross-body bag. From there we proceeded to our family vacation spot in the Utah mountains to spend a week. My purse, with the card inside, spent the week in a drawer in our condo.
On August 2 we drove over to Park City, checked in to a new hotel, and walked around the booths at the Park City Arts Festival. I carried my purse there, rather than leave it in the hotel room. But again I did not use it for any purchases.
The next morning, when I checked my email at 7 am, there was a fraud notice from the card provider. The suspect transaction was listed as a $20 purchase on August 3 ( that same day) at RNAVYHW, which the bank identified as a restaurant in Michigan when I called. There were also two $7 to $8 purchases at Walgreens, one on July 26 (the day we were at the Boise Walgreens) and another on July 28. Both were declined by the card provider. The fraud agent I spoke with said these were declined because the "address did not match". (I wonder why they did not notify me until the third suspect purchase).
So, given my use history, I cannot see how the card information was stolen, other than by a skimmer/scanner in the Walgreens store where I carried the card. Why they attempted such small amounts is beyond me; perhaps they were just testing the validity before making a major purchase.
Does anyone have an alternative explanation?
In any case, I am going to look into an RFID-blocking card holder for the rare occasions I need to carry the card along with me.
