Hi,
Interfacing peripherals with web app is always a challenge. Is is even more
with serial devices like POS printers and EMV terminals. There is basically 2
options I see:
1- Using some sort of plugin on the web browser that would allows your code to
access the physical world outside the browser. This create fragile setups.
2- Using either a custom build box (using raspberry Pi for example) or a
standard serial to IP interface that would connect to your app and provide the
interface to the serial devices and possibly any other peripherals required.
This box is assigned some identifier liked to a user of a user terminal.
With option 2, your server is connected to a set of real peripherals and can
communicate with them. You need to write the server part and find a way to
associate your connected user to it's peripherals. You also need to implement
the protocol used by the peripheral.
If your EMV terminals are IP, there is maybe a way to connect them directly to
your server.
I have done this for label printer and some dry contacts in a shop.
