What's the cost of this school lunch fingerprint identification system and the cost of maintaining it compared to other methods? ("Knappa students lunch," The Daily Astorian, July 29) New technologies tend to look great on the surface and initial fees can seem low but the often hidden cost of repairs and maintenance are usually an unwelcome surprise.

What about disease transmission? If one finger is cut, can another be used? How often will it be cleaned?

If it isn't using a full fingerprint scan, does the reduced point comparison increase the possibility of false identifications? Can parents monitor account activity?

There are many positives mentioned in this article but what's the downside?
