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