To order our catalog all fields of the form marked with an asterisk (*) must be filled out. In addition, the visual verfication must be entered correctly. If it isn't entered correctly, the following message appears: Captcha Code wrong. Your catalog order was not successful.
The visual verfication is for SPAM protection. Unfortunately, forms can be recognized on the Internet and automatically filled out with information. Without the visual verfication, we would have huge numbers of catalog orders without being able to distinguish between real entries and false ones.
There are many ways to design a SPAM protection. We have decided on the visual verfication as a combination of letters because it is a good compromise between impossible legibility for SPAM programs and good legibility for our visitors.
