DCQL query template for the Loyalty Card credential. It asks a wallet for the customer details, the card identifier and status, the point, mile and wallet balances, the issuing organisation, and the credential dates, in dc+sd-jwt, jwt_vc_json or mso_mdoc (doctype eu.europa.ec.eudi.loyaltycard). Use this skill when you let a member show a loyalty card from an EUDI Wallet at checkout or at a service desk, and you need the exact credential type and claim paths from the iGrant.io verifiable data registry.
