Luckily, there are some ways to make money with little to no effort. Credit cards often offer cash back as a reward for making purchases. What this means is, for every purchase you make, the credit card company will give you a small percentage of the money. The percentage differs between credit cards and categories. So, for example, one type of credit card might offer 1. An app called Inn can help you figure out which credit card is best for a particular category. You also often have to reach a certain threshold of payment to be able to cash in. And cards will often allow you to redeem your cash back as «points» to purchase things directly from the credit card company’s website instead. It’s generally a really bad idea to try to play the stock market unless you’re a financial professional. There’s one exception: index funds.
