A "Strafbefehl" is a penal order which is a simplified criminal procedure without a trial.

In place of the verdict the penal order is issued.

It is, however, equal to a verdict, if the recipient doesn't object within two weeks.

This means that the penalty is enforceable and might be entered into the "Bundeszentralregister" (federal central register) and also in a potential 

"polizeiliche Führungszeugnis" (criminal record certificate).
