What is the ‘Credencial’, or Pilgrim’s Passport?

The ‘credential’ is our Pilgrim Passport, the document that identifies us as pilgrims. It is the pilgrim record with which we are able to prove we have done the Camino and are able to receive the Compostela Certificate. It is obtained before starting the Camino and must be stamped along the way in places like churches, ‘albergues’, bars, restaurants, etc. You need at least two stamps per day during the last 100 km of the walk to receive the certificate.
