5_2 Encryption Validation

In order to perform a Debit, eWIC or EBT transaction, an encryption key must be injected into the device. During the loading process,
the encryption key and Key Serial Number (KSN) are injected. Only the KTK and KSN are visible for customer viewing.
An injected encryption key is also required for some MSR encryptions (e.g., Magtek, Monetra). MSR encryptions are enabled in the

customer. Follow the validation instruction, per your format. Refer to the following sections for encryption validation:
