A QR Object is an encrypted representation of a system object or an action that can be displayed as a QR barcode.

This QRs are generated by several functions of the API, and can be used in other functions

Each CASE (patient) of the Linkcare platform has an associated QR of type USER_REFERENCE.

This QR can be scanned by a PROFESSIONAL of the Linkcare platform to enroll the patient in a PROGRAM without the need of typing his personal data.

QR String representation

A QR Object is represented as a string with the following format:

Optional URL: It is possible to generate a QR wit URL format by defining the QR_BASE_URL configuration parameter (see WEB SERVICES CONFIGURATION ). If this configuration parameter is left empty, then the resulting QR will not have URL format and will be a plain string with the rest of components.
ID of the instance: The instance APP configuration parameter (see WEB SERVICES CONFIGURATION ). This value can be used to identify the Linkcare instance that generated the QR.
LKQR: Fixed string used by the API to identify that this is a QR generated by the Linkcare platform
QR object contents: an encrypted string containing the information of the QR
