In the past couple of years, there is a growing focus in the tech world on the topic of mobile payment platforms. The idea is to use smartphone apps loaded with money as replacement of cash in everyday business transactions. Paying for groceries, restaurant bills, and transport will no longer involve searching for petty cash, not only reducing time and hassle for digging through small change, but also dramatically decreasing possibilities of errors, frauds, and thefts while making it all the easier for tracking spending, checking available balances, and splitting bills across multiple people.
