![]() The company, as well as providing the electronic devices, also provides software and support, ensuring that all fields are covered to provide a fully provide a supported and strong relationship with their customer base. The main selling point of ST Micro Electronics is its provision of sustainable products, and introducing their electronics to create a more sustainable world. Their product line is micro electronic systems, such as switches, controllers, sensors and drivers. ST Micro Electronics is a global semiconductor company serving customers with innovations to have a positive impact on people's lives. NFC is a technical specification developed by the NFC Forum, an industry standards organization, and has recently been installed in smartphones for contactless payment and other applications.ģ9 Champ-des-Filles Chemindu Plan-les-Ouates, Geneva, The UHF band, which uses the ultra shortwave band of 860 to 960 MHz, can communicate up to 10 meters, whereas the HF band used by NFC can communicate over a short distance of about 10 cm. Therefore, NFC is a part of the RFID technology system. NFC is a uniquely defined standard using the HF-band communication method. RFID is defined as an LF band, HF band, UHF band, etc., depending on the frequency. They are often confused with each other, but what are the differences? RFID and NFC refer to technologies transmitting and receiving information through wireless communication. Another feature of RFID is that it can read multiple tags simultaneously, which is not the case with technologies that read labels optically, such as barcodes. The read information is stored in a computer and can be viewed, edited, and managed.Īs described above, RFID enables non-contact reading through wireless communication, so that information can be read even if the reader is some distance from the RFID tag. In active RFID, the battery-powered RFID tag actively transmits information, which is then received by the reader. Passive RFID uses radio waves emitted from the reader as operating power, and the RFID tag transmits the information entered into its memory. There are two types of reading methods, passive and active, and the difference is whether or not a battery is built into the RFID tag. RFID tags contain memory and an antenna for transmitting and receiving communication signals information is input and output through these devices. The cost, in this case, should be quoted individually depending on the system to be introduced. In addition to RF tag readers, some vendors sell software for product management, etc., as a set. Readers with limited performance can be purchased for as little as $100, but it should be noted that their use is limited by low read performance and terminal shock resistance. Prices for readers vary depending on their performance, but the price range for a handy type tag is about $2,000, while the price range for a gate type tag used in logistics warehouses is several million dollars. With the spread of RFID tags, the price of RFID tags is still on a downward trend, and it is said that in the future, the price may drop to as low as $0.01 per tag. The price of RFID tags, which used to be expensive, has been declining in recent years and depending on the type of RFID tag, the cost can be as low as $0.5 per tag. To use RFID, RFID tags and readers are required. Other attempts are being made to introduce RFID into product management at convenience stores to improve the efficiency of ordering and receiving and to reduce operational costs. The chip embedded in a driver's license is also an RFID tag, in which information such as name, date of birth, current address, legal domicile, photo, license type, license number, and license acquisition date are written to prevent forgery. The typical RFID applications include transportation cards and prepaid cards issued by railroad companies. However, installing a reader is costly, so the hurdle to adoption is high for privately owned restaurants and stores. It differs significantly from optical reading using barcodes and the like in that all information can be entered, erased, and rewritten. ![]() RFID tags can be read contactless using a reader. RFID stands for radio frequency identifier and is an automatic identification technology using short-range wireless communication.
