At present, there are many public transportation on the market, and the price of function and quality is also uneven, which points should be paid attention to in order to avoid stepping on thunder? Now let's make up the key points for you.
1、 Understand the operating system
Generally speaking, most of the swipe card machines on the market are Linux system and Android system. What's the difference between them
1. Linux system: it is a set of UNIX like operating system which is free to use and spread.
2. Android: is a Linux based free and open source operating system.
Android's kernel is based on Linux. In addition to the kernel, it is the mediation layer, database element, API and application framework written in C / C + +. Android applications are usually written on the basis of Java database elements. When running the program, the code of the application will be immediately converted into Dalvik DEX code (Dalvik executable). Then the Android operating system will run it by using the Dalvik virtual machine compiled in real time.
To put it simply, the Linux kernel plus some intermediate layers written in c/c++ and the applications written in Java are Android
On the whole, Android is better.
2、 Functional comparison
The function of the first generation of card swiping machine is monotonous, and the public transportation charging system only focuses on the one card public transportation card. With the popularization of mobile payment, the second generation of mobile card swiping machine also appears. The second generation of mobile card swiping machine adds a two-dimensional code identification camera on the premise of card swiping payment. Now we can take a bus without any change or bus card, only with a mobile phone, which is mainly due to the emergence of two-dimensional code card swiping machine.
3、 Screen comparison
Screen comparison is also one of the important factors that can quickly get the first choice. Monochrome screen and color screen are often ignored by the buyer. Although the content displayed is mainly the price deduction, the color screen will show a more high-end atmosphere when compared with the two, and the monochrome screen will be slightly less colorful
Preferred brand of card swiping machine
Brand means quality, responsibility, continuity, service, differentiation, uniqueness and so on. What about choosing a reliable brand? ——Shenzhen maiquan is a good choice. To choose a reliable brand, we must see his previous case experience to draw a conclusion. Maiquan has rich project experience and has undertaken many engineering projects, including "Beijing municipal public transport one card project"（ Many projects such as "Beijing public transport card reader", "Yangchengtong project (Panyu part)", "Shenzhen east public transport vehicle management system", "Shenzhen bus intelligent waiting system", "brush world POS cash collection system" have been running stably.
