About SWIPE-
Improved Attendance, Security and Accountability
Swipe is an innovative program for schools that improves student performance and accountability through advanced technology, proven methodologies, and valuable monthly incentives.
Swipe starts with more efficient data collection. Students check in when they first arrive to school by "swiping" ID cards at the school entrance(s). The swiping stations record the exact time of entry and print "Swipe Alerts" for students that have active alerts or messages. Each Swipe station can log in dozens of students per minute for fast, efficient attendance data collection. No lines, no waiting.
