Device is not PIN capable
From KB
This message will appear under two circumstances.
1 If you are trying to select the Debit prompt from the Sale screen while you are using either the Unimag or Walker Audiojack Readers
2If you are using the Miura device to accept a Pin Debit Transaction and your processor is not able to accept a Debit transaction.
The only fix for this message is to run the transaction as a Credit transaction, not Debit
