| #### Failure of the Signature Creation Unit | ||
| If the communication to the secure Signature Creation Device fails, the POS System can continue to operate until the SSCD is accessible again. Receipts created in a state where no communication is possible with the SSCD device are protected by the security mechanism of fiskaltrust.The fiskaltrust.Middleware will respond with the ftState = 0x02 "SSCD communication failed". The POS System receives the response and processes the data it contains. For following Requests no more communication attempts are done to avoid long waiting times for each Receipt request/Receipt response sequence. |

Might make sense to write a paragraph about the failed mode and why we introduced it (the "official" pattern is called "circuit breaker")
