Imagine, you are in the world where you buy groceries, but instead of cash or credit cards, you exchange food grains or chicken. Seems absolutely crazy, – right? Of course, we have come a long way and have experienced significant changes in the payment methods. Now, we have many choices to make payments such as cash, plastic cards, ACH, check and mobile payment. Payment methods have seen tremendous transformation over the last 10,000 years. We have used barter methods, coins, paper notes, check, and e-payment these days.
