Can Student ID Badges Be Read from a Distance of 20 Meters?

No, you would not be able to read all of the tags on students from 20 meters away, nor would it be a good idea to put "high-powered" readers on the walls to read the students' IDs. High amounts of RF energy—beyond the amount readers are legally allowed to emit—could be harmful to humans.
