Banking is an institution that can assist us in managing finances. They have a variety of services we can choose according to our needs. Starting from savings, mutual funds to financing. For those of us who live with the modern lifestyle must have been very familiar with the bank and the banking products. Basically, the bank wants to help us in managing our finances but also would ask for some interest from us as a return cause they have done it to us.
If we go shopping would be very risky if we carry large amounts of cash. So the debit card can be an alternative choice. Even you also can use the credit for the same purpose. But if you use a credit card you have to remember that the money you use to pay for your groceries are not really your money. So you must be extra careful if you do not want to get stuck into too deep debt. Use credit cards in emergencies only and not to finance your daily needs.
Interest charged on credit cards definitely greater than the interest savings, so you should think again if you want to use it. Are the goods you want to buy is really you need now and whether the funding would not be difficult for you in the future. If not, you can use it. But if it can disrupt your finances you should probably not use it.
