About NFC: NFC is Near Field Communication acronym for short-range wireless communications technology. First proposed by Philips, Nokia and Sony main push, can be short-range wireless communication between mobile devices, consumer electronics, PC and intelligent control tools. Allow consumers to exchange information simple and intuitive way to access content and services. NFC, also known as the short-range wireless communications, is a short-range high frequency wireless communication technology that allows non-contact-point data transmission between electronic devices (within ten centimeters) to exchange data. The technology consists of a contact-free radio frequency identification (RFID) evolved, backward compatible with RFID, first proposed by Philips, Nokia and Sony main push, mainly used in mobile phones and other handheld devices may be in. Because of the near-field communication has a natural safety, therefore, NFC technology is considered in areas such as mobile payment has great prospects. NFC contactless reader, a contactless card and peer to peer (Peer-to-Peer) functionality into a single chip, as consumer lifestyles pioneered countless new opportunities. It is an open interface platform that allows fast wireless network, active setting, and the virtual connection, a service to the existing cellular network, Bluetooth and wireless 802.11 devices. NFC is a short-range use 13.56MHz band wireless communication technology. Although the communication distance is only about 10cm, however, and the non-contact type IC card technology, "just touches", you can exchange data between different electronic products. Non-contact IC card different, NFC can be two-way communication. As long as support for NFC products and IC card, you can read or write data. But also between mobile phones and other portable devices to communicate. Data transmission speed is not high, there is 106kbit / s, 212kbit / s, 424kbit / s and 848kbit / sec in four speeds to choose from. NFC tag type type 1 is based on the provisions of ISO14443A, Innovision Research and Technology is currently the exclusive supply (TopazTM), has 96 bytes of memory, low cost, wide application. Type 2 is also based on ISO14443A, currently exclusively supplied by NXP (MIFARE UltraLight), memory is half Class 1 tags. Type 3 is based on FeliCa, currently exclusively supplied by Sony, with a large memory (currently 2 kilobytes) and a higher transfer rate per second (212KB), suitable for more complex applications. Type 4 is fully compatible with ISO14443A / B, many manufacturers have production, including NXP (typical products such as MIFAREDESFire). More memory, read rate between 106KB per second and 424KB, for a variety of applications. It is worth noting that a lot of memory differences between Class 1 and Class 2 and Class 3 and 4 label class labels, thus constitute two major categories. Basically there is no overlap in the various possible types of applications. Select the appropriate tag in the tag type specified in the four NFC, designers who need to be carefully considered in determining the relative merits of selecting each of which label before. Given the initial mass-market applications may focus on low-value, low-risk areas, NFC tags meet these needs must be balanced while balancing cost and performance, which is very important. At the same time, requiring a stronger performance of more specialized label application also has a certain market, is relatively small for considering these applications, cost and memory size. In smart poster applications, the user align the label poster embedded touch-tone phone to send the URL to the phone. Through the site, users can go to the relevant website for more details, or download coupons or tokens. Balance is required here is that, on the one hand tag is small enough, the cost is low enough for mass-market applications, on the other hand provides sufficient memory contains a URL length and some additional security features. In short messages or phone number shortcut application case, the user is aligned to embed an object tag touch phone can receive text messages or phone number is automatically sent. One possibility is for the new phone comes with the label in the box. You can save the phone number on the label or message text, and then secure it to the frame, align it touch the phone, you can get the telephone number of photographs of human needs, both interesting and useful, for the disabled or elderly bring great help. The label may also contain SMS text pasted into the inside of the door at home, the child came home from school as long as the touch of a phone, will be able to automatically send a text message to parents. This application memory requirements are small, so small size and low cost is a major consideration. In the MMS or ringtone download application, the user can touch the product or promotional items, make MMS or ringtone automatically transferred to the phone. At this small size it is still important, but it needs enough memory and security features. Memory tag on the greater the more information is transmitted directly to the phone. We must also consider limiting the short contact time between the NFC device and the label caused. Because of this limitation, in practical applications, the data exchange capacity of at most one touch of a few kilobytes. Company: Shenzhen innovation with the best electronic tag, Ltd.
