For a long time, NFC tags can only communicate with a single electronic device (mainly mobile phones. Recently, the dual-interface NFC tag launched by inside secure provides low-cost, fast, and convenient Product Support for interaction between two electronic devices. It can be predicted that in the future, NFC applications will no longer be limited to communicat

Like other information technologies, the emergence of NFC technology provides many possibilities for us to develop new applications, but it also faces various security problems. This article will introduce and analyze the five common security problems of the NFC system. 1. Eavesdropping Eavesdropping refersNFC link layer communication is not encryptedIn this case, if we do not perform some encryption pr

Tested, perfectly supported my reader acr122u NFC contactless IC card reader USB, my Mifare ultralight card. The release 1.20 of Springcard pc/sc SDK is now available in the Download sections of the website (direct link to Latest VERSION:HTTP://WWW.SPRINGCARD.COM/DOWNLOAD/FIND.PHP?FILE=PCSC-SDK). People working in the ' emerging ' NFC field would be is glad to discover the updated versions ofNfctool, a. N

I was confused by these inexplicable abbreviations when I first started to contact NFC. What exactly are the abbreviations of so many proprietary terms? What are the things ?! There have been some research over the past few days. Here I will record it as my personal understanding. If there are any discrepancies, please point it out! Let's talk about common NFC scenarios: 1. Reading cards, 2. Writing cards,

Due to NFC's ability to communicate in two-way and NFC's ability to be identified without power supply, coupled with the low cost of NFC, NFC is the first choice to replace RFID in some solutions, of course, there is a large limit on NFC, that is, the communication distance is too short (about 10CM ). Scheme rehearsal: 1. First, quickly build a mobile platform: I

NFC: Near Field Communication Technology RFID (radio frequency identification) technology, also known as electronic tags and radio frequency identification, is used by bus cards. Small NFC transmission range, secure and low power consumption RFID is a recognition technology, while NFC is an interactive communication method. Some people say that

As we all know, Windows Phone 8 SDK simulators do not support NFC testing. If you have developed an NFC-based application, it means that you need two Windows Phone devices that support NFC during the test. Such configuration may discourage many independent developers. The good news is that open-source projectsProximity tapperThis solution satisfies the requirem

According to reports from foreign media, Microsoft recently unveiled more detailed features of Windows 8.1 at the TechEd conference in New Orleans, which includes support for NFC printing and Wi-Fi hotspot features. For enterprise users, the addition of these two features will undoubtedly make Windows 8.1 more practical. Microsoft has said in the Windows business and springboard blogs that Windows 8.1 will allow the PC to connect to the printer in an

It has been 20 years since the advent of the Bluetooth Technology in 1994 and has now evolved to version 4.1. However, new connection technologies like NFC and WIFI all seem to be a threat to the bluetooth technology. Will Bluetooth be replaced eventually? What can Bluetooth do? Bluetooth is a wireless communication technology that enables wireless connection between local devices, such as data transmission between mobile phones, audio transmission be

The emergence of NFC (near-field communication function) is undoubtedly an innovation in the history of mobile phones. It makes mobile phones closer to people's lives, windows Phone 8, the operating system of the new generation of mobile phones, is also integrating NFC into Windows Phone 8. According to the wpcentral message, NFC is a globally standard data trans

from the previous NFC support type of card read, the following is to solve the NFC blocking response, if this step is not done, when the system has a number of NFC-enabled applications, will be in the NFC swipe when the number of application options, we need the scene is, The current app requires

The following code may help you to use the Cordova NFC plug-in function, you understand it, oh, say, this is the front-end HTML JavaScript method, non-Java plug-ins Prerequisite: Configure Cordova Plug-in method, still not on their own niang. An id= ' state ' text box or label appears on an HTML page to show NFC status. The key code is INITNFC, preceded by code generation. var app = {//Application const

Near-Field Communication (NFC) is a set of short-range wireless technologies. It usually requires a distance of 4 cm or shorter to initialize the connection. NFC allows users to share small data loads between NFC tags and Android devices or between two Android devices. NFC tags have complex classifications. Simple
