pointOfSaleInformation. encryptedKeySerialNumber

Combination of the POS terminal's unique identifier and a transaction counter that is used when decrypting the encrypted PIN.
The entity that injected the PIN encryption keys into the terminal decrypts the encrypted PIN and creates this value.
For all terminals that are using derived unique key per transaction (DUKPT) encryption, this is generated as a single number within the terminal.
This field is supported only for
Cybersource
 integrations and only for processors that support chip and online PIN transactions.
