The majority of credit and debit cards issued by banks are now ‘contactless’ which means they contain a small wireless chip called a RFID (Radio-frequency identification) tag which transmits data wireless. Simply using a RFID wallet which is usually made from or contains aluminium blocks the signals and makes it impossible to read the data […]
RFID is a general term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an object wirelessly, using radio waves. This is sometimes referred to as contact-less technology and a typical RFID system is made up of three components: tags, readers and the host […]
What is the RFID card developed？RFID has been used and depended on for over 70 years. In 1945, Léon Theremin invented an espionage tool for the Soviet Union which retransmitted incident radio waves with audio information. Sound waves vibrated a diaphragm which slightly altered the shape of the resonator, which modulated the reflected radio frequency. Even though this device was a covert listening device, not […]
What is RFID technology? Radio-Frequency Identification (RFID) is the use of radio waves to read and capture information stored on a tag attached to an object. A tag can be read from up to several feet away and does not need to be within direct line-of-sight of the reader to be tracked. Radio frequency identification […]
Automatic identification and data capture (AIDC) refers to the methods of automatically identifying objects, collecting data about them, and entering that data directly into computer systems (i.e. without human involvement). Technologies typically considered as part of AIDC include bar codes, Radio Frequency Identification (RFID), biometrics, magnetic stripes, Optical Character Recognition (OCR), smart cards, and voice […]
In recent years, Radio Frequency Identification (RFID) has captured the attention of manufacturing industries all over the world due to its sophisticated applications which include but not limited to high-speed inventory of items and efficient handling of materials. This article talk about rfid system components. Passive RFID tags – as opposed to the active ones, […]
RFID blocking technology refers to that prevents unsolicited RFID scanning and data harvesting that can lead to theft and duplication of credit card and personal information. This technology is typically part of an RFID-blocking wallet and creates interference to block most RFID readers. What is Radio Frequency Identification blocking? RFID blocking technology generally uses material […]
It is part of the ISO 18000-6 and is the most commonly used standard for the communications between tags and readers in ultra-high frequency (860 to 930 MHz). ISO 18000-7 is another widely-accepted international standard that specialized for air interface in the 433 MHz frequency band. Other ISO 18000 family includes: ISO 18000-1 Generic parameters for […]
Here are the interest for some RFID applications fields. We could know it. Agriculture Animal movement tracking is probably one of the first RFID applications being used. Nowadays, even more sophisticated farm management systems have been created that provide extra features such as ensuring correct type and amount feed to each animal, and animal health monitoring […]
In 2014, the world RFID technology applications market is worth US$8.89 billion, up from US$7.77 billion in 2013 and US$6.96 billion in 2012. For us, it’s a huge market we could do more to make our life better. The main privacy concern is that most RFID tags are small and may have the potential to track […]
