I don't know how much fingerprint scanning technology has progressed but making a Super Glue clone of your finger (just by letting it dry and peeling it off) can be effective on simple readers. More complicated ones check for more than just features, and may require conductivity or heat to work. Hard to say without you providing an exact model so we can see the features.
Harder problem is probably how you will fake it. If you're just signing in or out, someone will need to do it. Either you and someone else will need to take turns signing both of you out or you're going to have to drive back to work anyways.
Video related. Shows you can fake older, cheaper scanners. They waste time doing it by stealing the fingerprint. If you can make your own mold then you don't need to bother with all the extra steps.
