Can you make the question bit clear?Meant to say POS application uses the Web Application you developed to get the card swipe details and only those you want to send to server for further processing ?But again you have told that payment done b/w POS and Bank center.

after 2 weeks search around the web for find this solution, i reached this conclusion:
pos has a dll for work with pc,
first add dll as a reference to webApp
create a ocx control for cammunicate with dll
add this ocx to my webApp
use this ocx by object tag in payment page

<object id="Pec_PosDriver" style="display: none" codebase="\PosDriver.ocx" classid="clsid:4DF73FED-EAB1-48CE-B106-A71D330DE039">
</object>

how is work?
when user run the webApp for first, this ocx will install on client pc but with get certificate from user, in fact this ocx is an interface between my web app and bank, when user click "pay from pos" button, webApp wait for card swipe , this info will send to webApp by a javaScript function, this function fill empty text box for get payment info, when user click "pay" button, this info will sent to bank center via ocx, after transaction complete, result will send from bank center to this ocx, and my WebApp receive result of transaction, finally, successful transaction info post to server.
* this is a sophisticated problem,
it need to .NET,JAVA,ASP.NET,portProgramming ,
professional programmer from bank it center created this customized ocx for our webApp.

Why ActiveX if you use .NET? How a control can be an interface? what would it possibly mean?
