Doesn't even matter, you don't need to shop online to get any of those messages. It's just a scammer blasting out a test message to probably tens of thousands or even hundreds of thousands of telephone numbers. Those numbers can come from anywhere, random number generators, previous hacks of any business that requires your phone number, damn near anything. And yeah, just because you don't shop online doesn't mean your phone number isn't online in dozens of different places.
LOL!!!
Just wrap your head with aluminum foil for all the good it will do.
RFID scanning requires a person with a scanner to go out in public and scan for numbers. They have to be pretty close to you in order to do that, which opens them up to potential consequences. Or they can just buy a batch of 10,000 numbers online without ever leaving their computer. Which do you think is more likely?
The easiest way to get people's information is just to ask. Send out a text to thousands saying your package is lost, click here. Or there's a fraudulent charge on your credit card, click here. Bottom line is, don't click on ANY link you get via email or text unless you're damn sure it came from a source you're familiar with. The easiest thing to do is to go directly to the company website using a known link. So in this case, the message claims to be from the USPS. Well, don't click on the link in the message, go directly to the USPS website and try to look up the package. Easy. Same if it's your bank, go to your bank's website and look up your account the usual way. If there's no alert, or message, or fraudulent activity, the text was a scam. Most of those scams don't use viruses, a good virus is not all that easy to write and it can still be blocked by software. It's easier to just have a website that asks for information. When you enter your info, they get your identity.
A little common sense goes a long way.
