What does RFID mean?
RFID, or Radio Frequency Identification Device is a method of automatic identification and data capture. It’s used to track and measure all kinds of things – from products and devices, to people and animals.
Radio Frequency Identification (RFID) is already all around you. And as RFID technology gets smaller and smaller, and ever cheaper to produce, it’s going to become even more ubiquitous – with thousands of new uses, the risk of data theft is also on the rise.
But even though RFID is already all over the place, there’s a good chance you haven’t heard of it yet. First, because it’s too small to see. And second, because it’s mainly used by companies to power other features like parcel tracking, contactless payments and personal identification. So even though you’re already using RFID, you probably know it by another name.
It’s time to change that. Here’s our guide to RFID technology: what it is, where it came from, what it can do and where it’s going. If you want to know more about RFID, read on.
RFID-enabled items are embedded with an RFID tag (which contains an RFID chip). RFID chips are:
Cyber criminals with RFID knowledge can duplicate the contents of your wallet without you knowing it. This is leading to a new wave of cyber theft.
Surveillance can use RFID readers to read your passport from a-far, without you even realising it. This is an invasion of privacy.
How much information about you exactly is stored in RFID chips? A lot.
RFID tags are then identified and tracked by an RFID reader (or RFID interrogator). RFID readers come in two different kinds, just like RFID tags. Active RFID readers transmit radio waves that detect passive RFID tags. Passive RFID readers detect radio waves transmitted by active tags. Some tags and readers send and receive signals.
The evolution of RFID began in 1945, when the Soviet Union created an espionage tool that could re-transmit radio waves. In WWII RFID-like technology was also used to identify friendly and enemy aircraft. The first product patented as “RFID” was created by Charles Walton in 1983.
RFID is already being used in countless different ways such as:
These tags make it simple for a cyber criminal to steal the contents of your wallet, without even touching you. Buy Wallet Wall and protect yourself from data theft and protect the contents of your wallet.
