The credential is the official passport that accompanies the pilgrim and certifies that he/she is walking the Capuchin Walk. It is very important to have it with you because it gives you access to the pilgrim accommodations, which are all those hotels and restaurants that offer special rates to pilgrims. At each stop, the credential must be stamped with the relative stamps that certify the journey that has been done and, at the end of the pilgrimage, it can be used to obtain the  Testimony , the final parchment that certifies the completion of the pilgrimage. It is therefore important to remember to have the credential stamped every day. It is also a delightful souvenir to be preserved in time to recall the experience of the journey.
