How do I use TANs in my survey?

You can use TANs if you just want a specific group of people to take part in your survey. Every person gets one TAN and can only use it to generate one data set.
German manual: TAN-Vergabe.pdf

For bigger surveys with TANs you can buy the TAN-Assistant GrafTAN.
GrafTAN manages:

- adress lists

- sends e-mails

- prints labes and lists with TANs

- gives an overview of the survey's progress and shows which TANs have already been used

- sends reminder e-mails
