The Federal Bureau of Prisons (BOP), an agency within the U.S. Department of Justice, is conducting market research to identify GPS‑enabled monitoring devices with integrated two‑way phone call capability and associated monitoring and data‑management services. Devices must be secure, tamper‑resistant, and physically removable only by authorized correctional staff. The purpose of this RFI is to gather information on industry capabilities, commercial product availability, technical approaches, pricing structures, and best practices to support future acquisition planning.
