Mobile commerce is when people use their mobile phones or tablets to buy things online, just like they would on a computer. It's like having a store in your pocket that you can visit whenever you want. You can browse products, add them to your cart, and check out all from your phone. It's really convenient because you can shop from anywhere, whether you're waiting in line somewhere or just hanging out at home. And, you don't have to go through the hassle of going to a brick-and-mortar store, finding what you want, and standing in line to pay. Plus, many stores offer special discounts or deals to people who shop through their mobile apps or websites. So, that's mobile commerce in a nutshell, it's like having a store on your phone where you can buy anything you want without ever leaving your house!
