“At Pro Aurum, movement and vibration detectors add protection to the former Zuercher Kantonalbank branch in Kilchberg, a lakeside suburb of Zurich. Cameras hang from the ceiling to film employees as they fulfill orders from customers who can store valuables in one of the 700 safe deposit boxes or buy up to 100,000 francs ($107,000) of gold with cash over the counter without proof of funds such as a bank statement. About half of Buchwalder’s customers are Swiss, with Europeans making up most of the remaining clients. Pro Aurum, which also has units in Austria and Germany, trades ‘over a billion francs’ of gold per year.”
