Hi, is it possible to receive inputs from external hardware devices such as these? eg. [http://www.topazsystems.com/standardpads.html](http://www.topazsystems.com/standardpads.html) ---

Guy, were you able to solve your" Input from external hardware device" problem? I need a simple way to store bar-code scanned serial numbers in a database, and would love to use Knack. Let me know if you had success and any pointers. Thanks. ---

Guy, I have not had experience with these devices but in principle that should be fully transparent to a web app like knack, your computer handles the input to the browser.
