Billy and Geoff,
We used bar code labels in the equipment library it made booking equipment out quick and stopped typos. The equipment asset label had a bar code and we had a list of all the wards with appropriate bar code printed beside them.
The equipment was a scanner which went between the keyboard and PC so you did not need any specialist software, it just imitated the information being typed in. As this was quite a while ago the equipment will be obsolete by now but the idea might not be.
