About

NIBIN Data

Features
Read full description

NIBIN Data is something that would hopefully help any CSI/CSU NIBIN Techs with data collection, as well as any Law Enforcement that also gather and submit individual data. This application DOES NOT communicate with ATF or BrassTrax. This is simply to assist techs with collecting, maintaining, and later reporting information to their respective agencies. NIBIN Data allows for near-endless case management, with unlimited firearm entries, casing entries, and almost all relevant information one might need when preparing to submit for correlation. Additionally, as most agencies have their own internal trackers and worksheets, NIBIN Data also includes a CSV export option for your selected cases that can be customized in-app. Also, NIBIN Data also allows for the collection of basic photos of tested or collected firearms or casings, whether it be required by your agency or simply for reference. This application is not sponsored or endorsed by ATF or any other agency. This is simply a tool for LEO and other NIBIN Techs to use should they choose to, and hopefully make individual tracking of information easier to collect and prepare for data submission. All information is stored on-device and offline. There are no internet connections with this application for safety and security.
