Our QR codes are 5,906 characters of base64 in a Postgres text column, and the row has to exist before the image can be made

QR codes serve diverse functions, from simplifying WiFi access to managing venue entries. WiFi QR codes utilize a plain text string format, including security type, SSID, and password, allowing users to join networks without typing. Conversely, PubTrivia employs QR codes for table joining, utilizing a JavaScript function to generate URLs based on venueId and tableId. These are stored as base64 strings within Postgres text columns, requiring the row to exist before the image is created.
