That’s ok if the scanner belongs to a store, or someone who is supposed to be scanning your information because you are buying something from them.
The problem is the scammers, and thieves, who buy a scanner, and sit and wait for folks to pass by, so they can steal their information, and use it to buy things for themselves, for identity theft, or just to steal all your money.
These RFID blocking sleeves from BlockIt can help keep that from happening. Just stick your credit card in it and it blocks the scanners.
These are pretty too. I like the designs.
I have not checked to make sure these sleeves actually work. I’m told you can take them to a store, and use the scanners to see for yourself. I haven’t done that because I don’t carry the cards with me usually, as we are trying not to use them at all these days, and we live so far from town. And of course I keep forgetting.
I figure it can’t hurt to have something like that though. It is better to be safe than sorry.
