I have tried to install their bank project but it does not work
"It doesn't work" is probably the most useless problem report we get - and we get it a lot. It tells us nothing about what is happening, or when it happens.
So tell us what it is doing that you didn't expect, or not doing that you did.
Tell us what you did to get it to happen.
Tell us any error messages.

In this case, don't: go back to the manufacturers website that you got the code from, and ask their tech support. Chances are that either it never worked - in which case send it back for a full refund and try a different manufacturer - or you did something silly by mistake, and they can point you at what to do to fix it.
We can't: we don't have the hardware to test against, the software you tried to test, or the system you tried to test it on - and you p[retty much need all three of those things in order to get anywhere.
Any demo you find for that specific hardware will almost certainly be the manufacturers demo code that you have - nobody sits down to write demo code for "random hardware" - so you will almost certainly have the same problem even if you do find some. The manufacturer is the best place to start!
