If you got several credit cards, you know that you need to maintain discipline with regards to spending and of course paying the various bills off on time.
While this should be common sense, it's remarkable to see how many people either forget or simply don't do this one simple thing.
That said, you might be wondering whether or not credit cards can actually be used for more than just buying things.
Although, this is one of the things that many people will use them for, they can actually be considered a lifesaver when you think about it.
Consider for a moment that if you suddenly are in a car crash, and need to find a phone quickly but you didn't bring your cell phone, what would you do? Assuming there's a payphone nearby you could easily use your credit card to call for help.
Thereby ensuring that any injuries you sustained are not life threatening.
Something else to consider is that they can also ensure that you don't miss that the presentation because your car broke down.
They can be used to pay off an overdue bill and get the water turned back on.
They can also be used to give your pet life saving treatment.
The thing to remember with credit cards is that their usefulness is dependent on what you use them for.
Naturally, you can simply use them to buy things that you enjoy.
But they can also be used for more serious things and as such are an indispensable tool that you should not be without.
