FE-Schrift or fälschungserschwerende Schrift (falsification-hindering script) has been the only typeface used (except military registered vehicles which are still using the former DIN typeface) on new vehicle registration plates in Germany since November 2000. It was designed by Karlgeorg Hoefer for the German government in the late 1970s in the light of Red Army Faction terrorist activities, when it was discovered that with the then standard font for vehicle registration plates (DIN 1451 road-sign font) it was particularly easy to modify letters by applying a small amount of black paint or tape. For example, it was easy to change a "P" to an "R" or "B", "3" to "8", or an "L" or "F" to an "E". Modifications to FE-font plates are somewhat more difficult, as they also require the use of white paint, which is easily distinguished at a distance from the retroreflective white background of the plate, in particular at night. Faked FE-Schrift letters (e.g., "P" to "R") appear conspicuously disproportionate.
