Founded in 1852 by Hermann Giesecke and Alphonse Devrient, the firm initially specialized in high-quality printing, notably currency, and securities printing. From the 1850s to the 1870s the firm printed some of the important biblical editions of Constantin von Tischendorf. The partnership’s reputation for quality work was confirmed at the 1867 international exhibition in Paris.
In 1991, the German company Giesecke+Devrient launched the first SIM card. It was about the size of a credit card and called a Subscriber Identity Module (SIM). Originally, it was just an authentication tool that enabled simple cell phones to communicate. Since then, the SIM has evolved into a multifunctional security tool that supports numerous applications: from mobile banking to the connected car.
