Can anyone give me a basic overview of an MC9090 WM scanner?

I work at a company where IT works very hard at avoiding work, so I have to do this on my own. I have serial numbered, barcoded inventory I am wanting to scan. I happen to have a box of MC9090's with Windows Mobile that another plant dumped on us that have been gathering dust for over a year. I want to use those MC9090's to scan my barcodes rather than manually writing S/N's down on count sheets out in the plant. We have wifi in the offices but not all of the plant so part of this requires not being connected.

I don't have a high level picture of how these work, and everything on google is a sales pitch. The most basic solution here is make a flat file of S/N's on the device and extract to a PC to manipulate manually. We are talking 2,000 records on a bad day. That's all I really need to do. Is that possible with this device, and is there a canned program or can I write some simple code to acheive it?

Getting an asset request approved is harder than getting IT to work, so please no answers telling me to get something else. Either I cobble this together or I do nothing.
