I have a prepaid AT&T mobile number and want to use it's autopay option. But as I read and heard bad things about using debit card in online shopping, I don't know can I use my debit card or not? (I am an international student in US and my credit card is in the process until next month).
I also like to know can I use my debit card to buy something from Amazon, Walmart, etc.? Are they safe to enter my debit card number and information?
Big company web sites should be safe from hacking, but you never know. Getting a refund from Amazon might be tricky, though.
My kids use debit cards all the time for online purchases, but I'd rather use a credit card because the money is still in my control until I actually choose to make the payment. Thus, if there's a problem, I just don't pay that amount until it's resolved.
Bottom line: with a DC, the money is instantly out of your account, and getting it back in can be difficult.
Whether or not it is safe to use your debit card for online shopping depends on what website you are using.
AT&T is currently a reputable company. If you pay your cellphone bill using the AT&T website, that will probably be fine.
In addition to AT&T, the following businesses will not steal your money if you make a payment over the internet and using a computer:
If you think you are using eBay, make sure that small boring text at the top of your screen actually says, eBay.com
Note that a computer (or a cellphone) cannot display stuff on a screen unless that same computer has a copy of the data it is displaying. If you are reading a newspaper article over the internet, then your computer (or cellphone) has a copy of that newspaper article. That makes it very easy for computer programmers to create a copy of a webpage. Hackers sometimes make look-a-like (copy-cat) webpages.
A hacker might make a perfect copy of the home page of eBay.com and display that copy at:
Some criminals act as middle-men.
That is,
The moral of the story is: make sure it actually says ebay.com in small boring text at the top of your screen. Ignored the pretty-colored large eBay logo on the webpage.
If the webpage mostly looks like ebay.com, but says my-god-its-full-of-stars.com in the URL box of your web-browser, then do not enter in your payment information.
If you can see something on a cellphone screen with your eyeballs, then it is very easy for a hacker to save that information. If you see a photograph of a dog on someone's webpage, then saving a copy of that dog photograph is trivial. In fact, your computer already has a copy of the dog photograph. The dog photo you see on your screen is stored in something named "the web-browser cache". Your computer automatically deletes things from cache on a regular basis. If your computer did not delete the cache, then your computer would save a copy of every webpage you have ever visited. That would fill up your hard-drive very quickly.
Let us have an analogy. What you see with your eyes on a computer screen is like the physical building a restaurant or a clothing store.
Computers are like magic in the sense that a hacker can make a perfect copy of the clothing store (or any other building) by snapping their fingers. A hacker can easily copy the visuals you see at google.com.
The copy of a clothing store's building would have the same branding, the same logo displayed; the same signage on the front of the building. The copy of the building would look identical.
However, the copy of the building will be located at a different street address.
"gmail.com", "google.com," etc... are similar to street addresses, or physical mailing addresses.
Always make sure that the street address (URL, or web address) is correct before you walk inside the store and give them your money.
It is possibly to make a copy of mcdonalds.com and put the copy at sally-sells-sea-shells-by-the-seashore.com. It might look like mcdonalds, but it is located at a different street address / mailing address.
