In the early morning of November 10, the official ball of the 2018 World Cup in Russia was created with brand new technology. Called the "Telstar 18" (TV star), the football is printed on a gold-colored Russian World Cup Logo with a gradient mosaic pattern and a built-in NFC chip. Using many new technologies and innovative NFC chips, you can transfer data with your smart phone. Each ball generates a unique identifier that allows the user to unlock exclusive data messages. So what is NFC and what is the difference between RFID and RF technology?
RFID is a contactless identification technology, divided into two kinds, active and passive. The main working principle is that the RFID tag reader emits radio frequency signals through the coil of the electronic tag, and the reader reads and decodes the information to complete the entire identification process.
It automatically identifies the target object through radio frequency signals and obtains the relevant data. The identification work needs no human intervention and can work in various harsh environments. Long range RFID technology can identify high-speed moving objects and can simultaneously identify multiple labels, and the operation is quick and easy.
In recent years, NFC is a technology applied more on mobile phones, the mainly functions between two NFC devices is mutually interacts information and completes corresponding transactions when they are at a relatively close distance. NFC's biggest feature is the integration of readers and transponders in the same chip. It meets and simplifies information exchange, content access, service exchange between any two wireless devices.

Does the medical industry need RFID technology? The answer is yes. The fact that newborn infants are often characterized by similarities and are indistinguishable and lack their own ability to understand and express themselves and, if not effectively identified, often cause misidentification to be replaced. For the newborn baby, RFID tag associated with maternal and child, that is, the newborn babies and their mothers for the both sides associated with the logo, the same coding and other means to link the natural mother and child.
 
At all important entrances and exits installed long distance RFID reader, each time nurses and babies need to pass by reading the nurse's RFID identification card and the baby's RFID baby identification tape, the identity of the identity can be passed, Otherwise, the system will send an alarm to prevent the baby from being stolen. During the hospital, mother and child must wear the label.

The dream of an extremely flexible production structure would be that workstations are standing freely in the production hall grouped by certain production functions. The orders would navigate autonomously from workstation to workstation guided by their own working plans and by both efficiency and engineering KPIs. They would communicate as cyber-physical systems with both, the working stations and the entities providing the necessary material.
If the workstations were also designed to include redundancy, the flexibility would increase a lot. The Industry 4.0 scenario offers the opportunity of digitalizing objects via the RFID technology and connecting self-organizing orders and workstations.

At present, many industries have used RFID technology. RFID technology is closely related to the security industry, RFID technology plays an important role in applications such as intelligent transportation, intelligent parking, intelligent access control, RF anti-theft and other products and solutions.
Intelligent parking
With the vigorous development of the intelligent city, parking becomes an urgent problem need to solve, the importance of intelligent parking more and more prominent. The most common application for parking is automatic parking barrier system. An authorized cars would be tagged with an UHF RFID label, while moving towards barrier boom, the long distance RFID reader could identify the label and open the gate. Moreover, automated technology helps car drivers quickly find a usable parking space and provide drivers with precise navigation routes.
Intelligent transportation
RFID technology in the field of intelligent transportation is an important carrier of automotive electronic logo, also known as electronic license plate, is combination of UHF RFID technology and other related technologies. Based on the RFID technology of urban electronic transport system can adapt to a variety of mining environment, in the low visibility, multi-lane vehicles under normal driving speed can still be accurately identified to enhance the real-time and accurate urban traffic management, urban traffic more scientific , Intelligent.

Not all of the RFID reader devices with same specification, because different environmental conditions. So how to choose an ideal RFID reader products for your projects? First of all to understand the four parts of RFID system: tags, RFID readers, antennas, management software.
1. Distinguish what RFID protocol
If the reader is different from the label protocol, the tag will not be read. Commonly used protocols are 18000-6B, 18000-6C or EPC-GEN2. Each protocol has different characteristics and is suitable for different applications. If an RFID tag already exists, it must be determined that the selected reader is supporting the electronic tag. For RFID tags that have multiple protocols at the same time, RFID readers are required to support multiple protocols at the same time.
2. How many labels and data to read each time
Due to the different applications, the number of labels required to read is also different. Sometimes need to read only one label at a time, sometimes need to read more than one label, and the amount of data per label is relatively large. Different manufacturers and models of RFID readers in reading multiple labels and a lot of data in this regard is relatively large, especially once read a lot of data, read the speed will directly affect the performance. Hopeland’s fixed RFID reader could read 400pcs of labels one time and store over 100,000pcs of data offline.
3. Antenna matching
RFID readers have 2 types, hand-held and fixed, for the need of moving will choose handheld RFID reader terminal. For those who do not need to move, fixed RFID reader. Handheld terminals and antennas are basically one, you need to select the antenna efficiency of the reader. In some intelligent patrol, warehouses and other occasions, you could choose RFID reader handheld, to facilitate mobile reading information.
For fixed readers, sometimes need to consider multiple directions of the antenna, to select the reader can work with multiple antennas, in order to facilitate the installation of all directions to ensure that the label can be read, so the choice of the antenna is also very important.
