Kernrechtsfrage
Whether Postfinance took all reasonable measures against credit card misuse under Art. 148 StGB
Extrahierter Entscheid
Postfinance's identity check, limited income inquiry, and failure to require a minimum deposit were sufficient; an additional online check was not required.
Extrahierte Begründung
Reasonable precautions depend on the concrete circumstances, branch practice, technical and economic feasibility, and whether the measure could have prevented the loss. Given the low limit and the defendant's deliberate abuse far beyond that limit, Postfinance did not breach its duty.
