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.

Ios6 was released at the WWDC Conference held in June. Now, the focus of discussions on iPhone 5 is on hardware. Because ios6 addsPassbookFunction, it canUsed to store discount coupons and membership cardsSo some people have speculated whether the new iPhone will be built into NFC Technology (near-field communication, can allow mobile phones and bank cards to complete payment. The iPhone is likely to become an electronic wallet. If

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

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

Purpose of Use: Current activity can respond directly to an NFC tag without requiring the user to choose all the activity that can be handled.Steps to use:First step: In the OnCreate () method// NFC Front-desk dispatch system Private null;.........// initializes the pendingintent, and when an NFC device is connected, it is given to the current activity process

In May February this year, the NFC forum just released the first specification of NFC TechnologyNdef (NFC data exchange format)-That isNFC data exchange Specification. In less than two months, eclipse released the NFC development plug-in based on the ndef specification. This plug-in is namedAntares Software Development

According to foreign media reports, RIM's joint chief executive Jim Balsillie recently launched the BlackBerry Tag service at the GITEX conference in Dubai. With this service, users can share their contact information, files, and multimedia content by touching their mobile phones. RIM revealed that the BlackBerry Tag service will be integrated into BlackBerry 7 software updates based on NFC (Near-Field Communication) wireless technology. The first sma

S beam is a file sharing port developed by Samsung Galaxy s iii and applied to close-range data transmission. It is a new function developed based on the beam platform of android4.0 system. It allows users to easily transmit files without Wi-Fi or telephone signals. Two Galaxy s iii instancesMobile phoneWith just one click, you can easily transfer files quickly. Theoretically, a 5 MB MP3 file can be transmitted in just one second. First, let us recall the process and speed of two mobile

I don't understand why there are two standards in China: 2.4g and 13.56mhz. the backend protocols are easy to unify. Isn't it because of the differences in antennas? 13.56mhz is indeed a headache, and the traditional design volume is unacceptable: ApproachingBusiness card sizeAnd also consider pastingMAGNETIC FILM.

Filter NFC intent To start your application when you want to process the scanned NFC tag, you can filter out one, two, or all of the three NFC intents in your app's Android list. However, you usually want to control the most commonly used intent of the action_ndef_discovered type when the application starts. The intent of action_ndef_discovered type is rolled bac
