miji.beQR code in healthcare is a collective term for efforts to apply QR codes in medical settings to patient identification, medication management, sharing test results, facility guidance, and more. QR codes can store more information than one-dimensional barcodes and have an error correction function that restores data even when the code is dirty or damaged.
In patient identification, a code printed on a wristband is scanned to confirm the patient's identity. A GS1 page (as of October 2026) states that scanning with GS1 standards at the point of care helps reduce medical errors. In medication management, the GTIN (a product identification code), lot number, expiration date, serial number, and other data are stored in GS1 DataMatrix, a 2D symbol separate from QR codes, and used for tracking and recalls. According to the GS1 page on 2D barcodes (as of October 2026), GS1 DataMatrix is widely adopted in the healthcare field.
During the COVID-19 pandemic, QR codes were used in contact tracing apps and negative test certificates. Under the SMART Health Cards specification (version 1.4.0 / as of October 2026), whose development is led by VCI (Vaccination Credential Initiative), a voluntary coalition of public and private organizations, vaccination records and other data signed by the issuer can be presented as a QR code. The verifying party checks whether the signature is valid. If the data is rewritten after issuance, the signature no longer matches.
When using QR codes in the medical field, balancing their use with the protection of personal information is a challenge. One design, rather than storing personal information directly in the QR code, retrieves the information from an authenticated system via a short URL or token. With this form, even if a third party scans the QR code, it cannot reach the personal information without authentication.
Applications such as integration with electronic medical records and identity verification in telemedicine are also conceivable. Combining QR codes with a short URL makes it possible to change the destination after printing or to set an expiration date on the link.
