It is called micro lending for its small amount. Popularized by Indians residing in the Philippines, micro lending is the largest when it comes to number of customers. Small people like vendors fall prey to those usurers who charge 20% interest per month. And the come on is the small installment. Example, if you take out a loan of 500 pesos, you are going to pay 20 pesos every day. That 20 is very small compared to the principal amount of 500. And if you add the total, you will be surprised that you have to pay back 600 pesos in one month's time.
