Banks have always been there to accept deposits from people for safe-keeping and maybe even for earning a little interest out of those deposits and for extending credits to people who need money to accomplish an undertaking like set up a business, expand it or even engage in an entirely unrelated venture under the same business or company. Some people who need money for personal reasons like payment for school fees, buying a car or a house turn to banks to loan from them for an interest until they are able to pay for the whole amount that they borrowed over time.
