In the event of an emergency, time is of the essence, and having the right information available could be lifesaving. HD Barcode LLC developed a complete solution designed to assist with accessing important information such as blood type, allergens, medications, emergency contacts and other critical information should an injury or emergency occur within a corrections facility. HD Code Blue is a turnkey solution designed to help users embed comprehensive medical data of correctional officers and their emergency contact information into a private 2-D code that is only readable by department-issued approved reader devices. Other areas that the barcode can be used is to match a court document to a inmate. The company even created IrisCheck to match an individual’s iris to its code, and is currently working on doing the same with a fingerprint.
