A universal electronic card is like a special card that can do lots of different things! It's like having a magic wand that you can use to pay for things, prove who you are, and access special places.
Just like how you have a special card to get into your school, a universal electronic card can let you access lots of different places like the library, the gym, or even your doctor's office.
But that's not all! This card can also help you pay for things like groceries or clothes. You can just wave your card over a special machine and it will take the money from your card instead of using cash.
And because it's electronic, it also keeps track of all the different things you use it for. This makes it really easy to keep track of how much money you have on your card, where you've been, and what you've done.
It's like having a really cool superpower that helps you do lots of different things!
