QRefer: Using 2D-Barcode Technology for Patient Referral Systems.
2D barcodes have high potential for use in the medical field. We developed QRefer, a Web-based application, which uses QR codes to transmit medical data for a patient referral system. QRefer demonstrates the value of 2D barcode technology for health and medical applications, particularly in patient data security, identity verification, and continuing medical care.
