Have you ever wanted to have a special card that does special extra things? Well, guess what? These amazing cards are real! They are known as 13.56 MHz cards and they have two extremely cool capabilities: access control (getting you into places) and payment (procuring goods and services).
A tiny computer chip is embedded inside these cards. It is sort of like a little brain that knows precisely who you are! A magic moment occurs when you place the card near a special reader. The reader speaks to the chip, and the chip responds. Instead it is like a special password only certain people understand.
Let’s say you want to enter your school or a special room. Instead of looking for a key, you wave this card in front of a reader. We read your card to see if you get in. There, the door opens like some kind of magic — if, of course, you are supposed to be there. No keys, no waiting, just fast and easy.
They also make great items for purchasing. Let’s say you have a great craving to buy some snack or some toy. You never have to pull cash out, neither do coins need to be counted. Simply hold the card near the payment machine and boom! The payment is done. It’s fast enough that you’ll be snacking away in no time.
These cards are super smart. Ideas like them are so difficult for others to copy that they protect things. Your custom card is only usable by you. They move fast and get people to where they need to go. It's like a superhero card you keep in your back pocket!
One day, there may not even be a card. You could do all of the above on your phone! Picture performing tasks like opening a door or purchasing a snack with the simple tap of your phone. Every day technology is making our world more fun and simplified.
Such cards are manufactured by some special companies like SUNLANRFID. They put in the work to ensure the cards are secure and operate as expected. How to make our NAND world better: These are like card wizards of companies.
