Technik Serif is a serifed version of a Technik constructed typeface, which is almost strictly designed from basic geometrical elements consisting of mainly circles, also squares and diagonal shapes. Another characteristic is the connection of diagonals, verticals and diagonals, and also of some circle shapes touching each other at one point. It gives this type an original look, and prevents the problematic dark places in some letters. Technik is not designed as a text typeface, it is recommended mainly for display typesetting. You can use it for example in branding typography, or everywhere where you need the technical feeling of the constructed typefaces to look less cold and more friendly.
