Waterloo, IA school district is looking to introduce ID badge system for visitors. The system called Raptor, made by V-soft compares driver’s license data with 48 states sex offenders record. In case a visitor is listed as a sex offender additional safety precautions can be taken. Every school visitor would be issued a disposable photo ID badge to wear, it would list school name, visitor name, time of admission and visit destination area. System is expected to be implemented by the end of March.
