This is a Servas passport that is used in all member countries. Most of the details on your Membership Application Form are on it. When you travel, you always take the paper version with you to show it to your host family. While contacting Servas members by e-mail when preparing your trip, you can send them the pdf-version.
You have to apply for an LOI. The Travel Coordinator sends you a paper version with a validation stamp and a date (the LOI is valid until one year after the date of purchase). You pay € 16.00 for this. You will also receive a pdf-version by e-mail.
