Start by reading the documentation that came with the barcode reader.

Most barcode readers come preconfigured to act as a keyboard: you scan the code and to your app it looks exactly like the user typed the number in. That's probably not helpful to you!

However, most scanners can also be configured to provide "lead in" and "tail out" sequences which would allow your code to spoty that a code has been read by monitoring the keyboard input. Detect the lead in and start assembling the code, detect the tail out and set off the timer - not difficult to do.

However, how you setup the scanner is down to the manufacturer - so you'll have to contact them to work it out - I'd start with their website then check thier tech support if necessary.
