Transportation of BKM is the domain of the application using the Engage Engine. For example, in implementations where human-processable data (e.g., passwords, passphrases, numbers) are involved, that information can be conveyed through out-of-band means (e.g., one-on-one interactions between team members, secured emails). Some implementations choose to use more exotic transport methods, e.g., encrypted QR codes, where the QR code itself is protected by a password known only to those using the QR code.
