Abstract: Systems and methods for data transfer and platform integration using quick response (QR) codes are provided. The system generates first item data associated with a first property item, generates one or more QR codes that encrypt and store the first item data, and sends or displays the one or more QR codes. The system reads the one or more QR codes from an application program installed on a computing device to obtain the encrypted first item data. The system decrypts, using a decryption key, the encrypted first item data to obtain the first item data from the QR code. The system generates, by the application program, first analysis data based at least in part on the first item data.
