Micro-credit is the term, which is related to banks, finance and economics of a country. It was first introduced by a banker named Professor Muhammad Yunus. Micro-credit is the process of giving short and long-term loan to the poor people. In the developed countries, people can get different types of huge loan from different financial organisations and even from the government. They can use that loan-money for their business purposes, for constructing their residential buildings, for buying a brand car and many more. But in the poor and developing countries like ours, we cannot get a huge amount of money from any financial organisation and even not from the government. Living in the third-world countries we cannot afford to run a big business nor can we execute an industry because most of us live below the poverty line. On the other hand, we can't revive our cottage industries, small industries, handicrafts and our cultural products due to the lack of proper finance. That is why our national progress is retarded and not on the increase. In this case Grameen Banks and some other banks have come forward to take valiant and challenging steps for the development of our country. These banks give the poor the opportunity of microcredit for their own development. Proper steps are taken to ensure the best use of money lent to the poor. The system of lending money of micro-credit process is so flexible that people can pay money from their profit. So, this process has gained popularity in our country particularly in rural areas and it has been acclaimed by many western countries. They are now following the micro-credit system to alleviate poverty of their countries. So, with the micro-credit system, the poor can be able to lessen poverty and change their lots. Gradually they can develop and play a vital role in the economical development of the country.
