POS终端编程 [英] POS terminals programming

问题描述

大家好，哪种编程语言最适合在POS终端上部署应用程序，以及如何使其基于服务器。

Hello guys which programming language is best for deploying applications on the POS terminals and how do I make it server based.

推荐答案

POS终端的制造商/供应商通常用已安装的（定制）应用程序销售它们 - 我相信它们使用''c''，但它实际上取决于芯片组，cpu等POS终端建立在



和''我如何使它基于服务器''...你是什么意思？

the manufacturer/supplier of POS terminals normally sells them with a (customised) application installed already - I beleive they use ''c'', but it really depends on the chipset, cpu etc the POS terminals are built on

as for ''how do I make it server based'' ... what do you mean ?

POS公司是否发布了SDK或类似的东西？如果他们确实提供了SDK，那么应该有一些关于如何在设备上构建和安装用户应用程序的文档;之后，根据您要在设备上进行的软件的实际要求和规格，由您来做一些R''''D.



制作基于服务器的应用程序通常有两件事：客户端和服务器。



客户端（POS）是一回事，真的非常依赖于设备本身及其提供的内容（SDK / API），即使它是基于Linux的。

服务器是另一回事（我没有太多服务器端的经验）但我认为你需要一个好的沟通层，一个好的数据库和交易层。



最重要的是，你需要客户端和服务器之间非常好的安全和加密，否则你的系统将成为黑客窃取数据（个人信息，信用卡......）的目标，如果发生这种情况，请告别你的快乐工作！



祝你好运。



Max，

Does the POS company releases a SDK or something like that ? if they do offer an SDK, there should be some kind of documentation on how to build and install user application on the devices; after that, it is up to you to do some R''n''D based on the actual requirements and specifications of the software you want to do on the device.

Making a "server based" application is usually 2 things : The Client and The Server.

The client ( POS) is one thing and is really really dependent on the device itself and what it offers (SDK/API), even it is Linux based.
The server is another thing (I don''t have much experience server-side) but I assume you need a good communication layer, a good database and transaction layer.

And the most important, you need VERY GOOD SECURITY AND ENCRYPTION between the client and the server, otherwise your system will be the target of hackers that will steal data (personal info, credit card, ... ) and if that happens, goodbye your happy job!

Good luck.
