TDN transfers are very simple. The sending entity passes TDN Signature to the receiving entity and the receiving entity request the TDN ownership. If Get Ownership transaction failed the transfer is invalid.

The TDN can be transferred as a computer file containing the TDN Signature , a barcode image file or a barcode printed on paper or digital device screen. The transfer can be performed face to face or using regular mail email, SMS, social media, video telephony, FTP or any other means for transferring digital data. For security it is a good idea to protect the TDN with a PIN and sent the PIN separately

If the two entities involved in the transfer trust each other the receiving entity may not request the ownership of the TDN received. . Theoretically the TDN is considered compromised but in this situation it is less likely a fraudulent transaction will be performed on that TDN. The new owner of the TDN assumes that the previous owner was not unknowingly in the possession of an already compromised TDN.

If the TDN is secured with a PIN or a PKI it has to be removed before performing the transfer or the PIN has to be passed to the receiving entity. Sharing a PKI is possible but it is not advisable.
