Hello everyone! Today we are going to talk about small disc magnets. You have probably seen a hologram on your credit card or school ID. So, have you ever tried to understand how they work and why they are needed? Let’s find out together!
Even if you look closely, at a plastic credit/debit card from behind, that strip would be black — those were magnetic strip And those stripes were made of tiny segments of magnetic material specifically oriented to store bits. The card reader picks up the information on the strip when you swipe your card through a card reader, and it has its own special piece of technology specifically designed to read what is stored on this strip. Magnetic stripe technology. That's its name. It is used in many other ways that are nowhere near as exciting such as hotel key cards, driver's license or security badges. So only one person can use the things or places.
Magnetic strips can carry a WHOLE LOT of information on them! For instance they go on to save, that your name and an account number stored in your credit card, the hotel room you are putting up at or getting into a specific wing of a building. Because it allows so many of them to be used in place of cash, Some fitness trackers, like Fitbits are even made with steel and magnets on the back sides so you can track steps and workouts! Kind of goes to show how beneficial they really are in our lives.
Now, the innovation gathering is one approach to gather and we are as yet utilizing attractive strips however there are new advancements which are beginning to pick up help. These days, just about every credit and debit card has a small processor chip in the card — not just the traditional magnetic strip. Called an EMV chip, these chips are virtually impossible to copy compared to traditional magnetic strips. This means that your details are safer, and undergoes secured processes. With NFC (Near Field Communication), maybe sometime in the future, we could even pay with our phones or smartwatches. This is the tech that enables us to wave our phone or watch at a card reader to pay. Never fear, the magnetic strips will be around for a bit longer — we'll just keep swiping them.
Electric strips, then what magnetic stripes LOL They have made our lives so much better and easier! Have you ever go to a store, and realised that you left your cash at home? With the magnetic strip technology, all you need to do is swipe your credit card through and pay for anything. In this regard, it could be a blessing in disguise as you may reach the college late and do not have those hard coins in your pocket. They keep an eye on everything that we pay (what do we spend) and the savings (how much money is left in our bank account). We would have to catalogue every purchase, balance our own checkbooks and not know what will be debited for days after the fact.
So there you go… a quick overview of Magnetic Strips! But, but so small so simple are they But, butso little oh and thusobviously necessary.. Each time you go to use another credit card, or flash your ID while going out of the office, just remember that in the end this is all about little magnets and how they're improving our lives step by step.
