Staff ID Cards

My district is pretty tiny. In the 23 years I've worked there we have never had ID cards, never really needed them. Everyone knows everyone, we punch in codes to check out books or eat lunch. So the concept of needing Staff ID cards never really came up. Then suddenly businesses everywhere start offering discounts & free stuff for teachers - you just have to show your staff ID card. Well, everyone likes free & cheap stuff, so I took it upon myself to make us some ID cards (I was under a deadline as McDonalds is offering free breakfast to teachers next weeks!) I thought about putting a barcode or something on them to make them "official" looking, but what good is a meaningless barcode? These ought to do the trick!
