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

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

, Braun and Philips. Although the product specifications and prices are almost the same, but the Korean brand products look more complex than foreign brands of products. "Why is this so?" "I asked my two companions that they were all usability experts. "Because Koreans like things that look complicated. "They answered. It is a symbol that reflects status. In the shop, I marvel at the high complexity of all the instruments-especially those that used to be simple.
