SDK · Nokia Nokia is worthy of being the leader in the mobile phone industry. It also provides first-class support for j2's. There are specialized websites that provide sdks and various documentation. Web site: http://forum.nokia.com.cn/sch/index.

0x00 Preface I have always wanted to play wireless security, but wangcai said that the threshold is low (where is it low? =. = Web dog: I am stupid, Wang). I started ACR122u and wanted to get into trouble from NFC. Now I have read this article to

BS structure of the system, the client has installed the RF card reader, the driver is also installed, working properly. After the customer login system through the browser, want to directly through the browser to access the card reader, can be

  The previous sections describe the modules of the check-in terminal.ProgramIt is much easier to do, but the actual implementation still requires a lot of energyUIIt is always laborious to do something. However, the technical level is

  This article describes the various modules of the system as a whole to understand the process of forming the system surface. First, it is clear thatCSSystem, the system has offline requirements, and more importantly, the client needs to

  There is nothing to talk about in this article. I just want to mention something different from the client. The biggest difference between a server and a client is that it does not face a single connection, but some connections. For

  Now let's get started. First, let's briefly describe the functions of the entire system, mainly laying the groundwork for some of my designs below. The sign-in system is divided into two parts: front-end display and background management

  The formal approach to data synchronization is to useSQL-ServerBut copying is a little tricky here. From the very beginning, considering the size of the client database and other requirements of the clientMSDEInstall oneSQL-ServerIt is a

  This article is not yet ready to enter a substantive stage. First, inserting segments is related to the exception handling part of the entire system. The most basic principle is, of course, all exceptions that may affect the normal operation

  After the two interfaces defined in the previous article, the menu and toolbar basically matchCommandMode, you can load it in the system. But theoretically, it is one thing to follow the pattern, actually writingCodeIt is another thing. We

    Product Introduction     Chip: NXP Mifare 1 S50 Storage Capacity: 8 kbit, 16 partitions, two groups of passwords per Partition Operating frequency: 13.56 MHz Communication speed: 106 kboud Read/write distance: 5-10 cm Read/write time:

tianchun, director of the Microelectronics Research Institute of the Chinese Emy of sciences, told reporters that at present, China's information network and transmission infrastructure is good, but it is still weak in sensor and chip manufacturing, integration, preprocessing, and other aspects, at the same time, the software technology of massive information processing is also very weak. Software technology supporting data collection RFID middlewa

ISO14443 standards Transmission speed: The transfer rate can be 106KBIT/S, 212kbit/s, 424 kbit/s RFID reader through the antenna and RFID tag for wireless communication, can achieve the label identification code and memory data reading or writing operations NFC uses two-way recognition and connectivity, and there is no fixed master-slave relationship between the parties, and communication

Recently saw a classmate in order to enhance the mobile phone GPS signal, the antenna DIY to the outside, pulled a very long antenna, their own in the suspicion that this is in line with the principle of antenna design, can really make the signal enhancement? So find the following article to learn.1. RFID Fundamentals RFID (radio frequency identification) is an automatic identification technique for comm

concerned by many vendors, many well-known manufacturers have launched their own cloud storage services such as Amazon's simple storage services S3, Google launched the online storage services gdrive, Microsoft launched the Windows Azure storage services.The use of local networks or the Internet and other communication technology to the sensors, controllers, machines, people and things through a new way together, the formation of people and things, t

This article uses the latest Penetration tool RFID snitch (Tastic RFID thief) and RFID induction hack technology to gain access to some buildings that have security.Tastic RFID Thief is a silent long-range RFID reader, can not be known to steal

learn your business and then launch a customized solution that meets your needs, which will eventually cost you more money. Stay away from vendors who only know the process and do not know your business in this industry. Find a vendor that understands the future development direction of this industry and is very familiar with industry standards, relevant processes can also be integrated into their standard ERP software solutions to address these ne

world's IoT business will reach 30:1 compared to human-to-human communications, so the internet of things is known as the next trillion-level communications business.The IoT industry covers sensing, transmission channels, computing processing, industry applications and other fields, including RFID radio frequency identification, sensors, wireless network transmission, high-performance computing, intelligent control and so on.2. IoT Cloud Platform Bui

How to develop the underlying hardware how to write an interface documentThese days in the supermarket RFID clearing system of the upper computer program to write, with the vb.net. The bottom is used by others to develop a good SDK, why write this article? Recently, because of the functional limitations of the device at hand, I looked for other companies on the Internet RFID card reader, because I was to do
