A single paper and digital credential
The credential is the "passport" for the pilgrim/hiker, attesting to their identity and distinguishing them from other travelers. The credential is required for access to the Posadas and to benefit from discounts at affiliated facilities.
In addition to the pilgrim's personal details, the credential records the place and date of arrival and departure, and provides spaces for stamps confirming passage through the different stages of the Way.
The digital equivalent is the Mìnera Card, a digital web app that, in addition to collecting digital stamps, allows users to benefit from discounts on accommodations, dining, museums, points of interest, shops, and services available along the entire route.

The credential is issued by the Fondazione Cammino Minerario di Santa Barbara and can be purchased online for a fee of 10 euros, which includes the Mìnera Card, at the sales points listed below, or directly at the Foundation’s headquarters at Via Cattaneo, 70 Iglesias (SU), open Monday to Friday from 8:30 am to 12:30 pm and from 2:30 pm to 4:30 pm.
If purchased online, the paper credential can be picked up on site at the external box or shipped to your home. Please specify the collection method during the purchase process.
