For a fluidity of identifications, instead of writing in the reminder notebooks, I developed this application which exchanges QR Codes containing basic information such as name, first name, address, city and telephone number . The texts are written in clear in the code and do not require connection or redirection to an online file. The data is stored in the devices but can be read by any device with a QR Code reader. You can present your QR Code, scan or record new information.
