A Variety of Smart Cards

Overview of NFC Tags

Near field communication (for short NFC), also known as the short-range wireless communications, is a short-range high frequency wireless communication technology that allows electronic devices for non-contact point-to-point data transfer (10 cm) exchange data. This technique is evolved by contactless radio frequency identification (RFID), and backward compatible with RFID, first was successfully developed by Sony and Philips respectively, mainly used for M2M (Machine to Machine) communication in mobile phones and other handheld devices. Natural near-field communications security, therefore, NFC technology that has great application prospects in areas such as mobile payment. In order to promote the development and popularization of the nfc tags, the industry has created a non-profit standards organization - NFC Forum to promote the implementation and standardization of NFC technology to ensure that the collaboration between the equipment and services. Currently, NFC Forum in the world with hundreds of members, including: SONY, of Philips, LG, Motorola, NXP, NEC, Samsung, Atoam, the Intel, and the China members have China Mobile, Huawei, ZTE, Shanghai Tongyao and Taiwan Cheng Loong and other member companies.

UHF RFID Tags

uhf rfid tag technology is becoming matured, and it can provide the unprecedented, near-perfect solution for supply chain With RF. In other words, the company will be able to know in a timely manner the location information of each commodity in any point in time on their supply chain. How to identify and track the supply chain on every single product in it? There are several ways you can achieve, but we have found the best solution is to give each product unique numbers - "license" - Electronic Product Code (EPC). EPC MIT AUTO-ID Center in the United States at the beginning of this century, it is a very state-of-the-art, comprehensive and complex systems.

Development Prospects of NFC Tags

NFC tags have the features of low-cost, easy-to-use and richer intuitive, which make it even more potential in some areas - NFC can achieve through a combination of a chip, an antenna and some software, a variety of equipment in a few cm range communication, while the cost is only 2 to 3 Euros. The smart card manufacturer takes advantage of this great feature to research and develop the good and affordable NFC smart cards for the mass market. According to the latest research ABI Research about NFC market fortune in mobile handheld devices. ABI estimates that since 2005, the market appears smart phones and enhanced handheld devices using the NFC chip. 2009, handheld devices will account for more than half of the market. The research firm Strategy Analytics forecast, to 2011, the global mobile phone-based contactless payments will amount to more than 36 billion U.S. dollars. NFC technology gained popularity, it will greatly change the way people use many electronic devices, and even change the way the use of credit cards, keys and cash. NFC as an emerging technology roughly summarizes the Bluetooth technology interoperability ills. However, it is not completely replace Bluetooth, Wi-Fi and other wireless technologies, but on different occasions, different areas play a complementary role. NFC data transfer rate is low, only 212Kbps, and not suitable, such as audio and video streams, and other applications that require a higher bandwidth. The so-called RFID standards and NFC standards conflict is a misunderstanding of the NFC. NFC and RFID in the physical layer, there are similarities, but its own and RFID are two fields of technology, the RFID is only one kind of the labels through wireless identification technology, NFC is a wireless communication method, and such a communication method is interact.
