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 NFC is an improved version of

Car: It is charged at a designated place. After receiving the food delivery instruction from the kitchen, it is a table number ). There are black tracks and RFID tags on the ground in the restaurant. The black tracks are used to track the car and do not run around. RFID cards contain the number of the table. The car first enters the kitchen to pack the food to be sent, and then follows the tracking li
quarterly: what does this mean to your customers? If you are a company-and I am a bank, or I am a retailer-please tell me what these technologies enable me to do? What are the potential impacts of such collaboration? John Chambers: Okay. Let's assume that productivity increases by 5% every year ~ 10% is feasible. The first thing the CEO says is, "What is the productivity improvement margin in our industry? In what ways are we leading and lagging behind? Here is an example ". When a customer ent
goals. In the process of employee growth, there are usually two situations: 1. Fast-paced improvement. The disadvantage is that when an employee reaches the top of his/her career, he or she no longer has room for development because he or she has lost his/her work enthusiasm and even left the company; 2. Slow pace improvement. Its disadvantage is that employees cannot get effective incentives for career development or learn the knowledge of other positions. Enterprises should arrange their pos

Super Menu Type
The Hyper-menu navigation on a mobile device is similar to the Super menu navigation used on a Web site, which groups a large coverage panel to display menu options that have been well defined. The Ripcurl website uses the Super menu to show the secondary categories of costumes.
The WebOS version of Facebook uses the Super menu to streamline navigation, avoiding the plethora of options in springboard na

At the last summit forum, I talked with some bloggers about the two hot topics of IOT and smart planet. During the conversation, I found that from a technical point of view, there are many similarities between the two, and this article is a summary of that sentiment. This article will first introduce the concepts of IOT and smart planet, and then introduce the technical differences between the two and their relationship with cloud computing.
