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

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

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

Comparison of near-distance communication technology and near-distance communication technology Comparison of near-distance communication technology Compared with the traditional near-distance communication, near-field communication (NFC) provides natural security and fast connection establishment. The comparison is as follows: Table 2.1 comparison of communication parameters NFC Bluetooth Infrared Network Type Point-to-Point Single point to multiple points

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

Iot, cloud computing, and mobile development are all fire-fighting concepts that represent a revolution and an effort to pursue a new model. These are not revolutionary concepts. In today's context of technology, products, and market, it is difficult to create revolutionary things. More is a long evolution. Let's talk about Iot 1. Iot is based on wireless technology (at least in most cases ). 2. The Internet of Things may bring a lot of social problems: personal privacy, national security, etc.

WiFi-based electronic tag Locating Algorithm With the rapid development of wireless communication, the combination of indoor positioning wireless networks and RFID technology has become increasingly concerned. People's demand for items and personnel positions is getting stronger and stronger. Outdoor positioning, such as well-known GPS positioning, has already satisfied many people, but once they enter the room, due to the blocking of buildings and t

1.Project BackgroundThe RFID tag is the physical carrier of the product's electronic code (EPC), which is attached to traceable items and can be circulated globally and recognized and read and written. RFID (Radio Frequency identification) technology, as the key technology to build the "Internet of Things", has been paid attention in recent years.At present, UHF RFID
