Swico Recycling Data protection service There are specialised companies that destroy data for customers for a fee. For example, in cooperation with Swiss Post, the company SafeRec (www.saferec.ch) offers a solution whereby used devices are sent to the company by standard or registered mail. They are destroyed and shredded in accordance with DIN 66399 and a certificate of destruction issued. The packages handed over at the post office counter do not leave postal circulation, but are destroyed and shredded on the premises of the post office in the data shredder from SafeRec AG in accordance with DIN 66399 (security level to “secret data” ). A certificate of destruction is then issued by email.
