SEC: student/fac. barcodes

[Mary Powers <Mary_Powers@WINDSOR.VEGS.TOGETHER.ORG>]

I'm seeking practical experience tips for storing student & faculty barcodes
after automating.  I'm not interested in giving the students laminated cards,
but prefer keeping them on a rolodex (what style is best?) or in a binder?
Do you arrange them by grade or alphabetically?  Do you keep faculty barcodes
in a separate place? Finally, do you allow students to find their barcodes
and scan out material themselves?
I just automated with Winnebago, & have read that some use slide pages;
others say a rotary Rolodex lets cards "fly" out if students use it---so am
looking for useful advice.
