They serve as a backup for devices lacking NFC for Smart Tap. The API uses a `RotatingBarcode` type with parameters like QR code type, value pattern, and TOTP details (algorithm, period, parameters). Multiple redemption methods (Smart Tap, rotating barcode, static barcode) prioritize based on device capabilities. For security, it is suggested to call the 'object:insert' API, use an OTP secret key that is scoped to a single pass, and refer to the specific object by ID in the JWT.\n"]]
