The Redemption Issuer ID represents a merchant, while the Collector ID uniquely identifies a terminal requesting a merchant's pass. A Pass Class ID, formatted as `issuerId.classSuffix`, identifies a specific pass tier. These IDs facilitate the exchange of information, enabling merchants using different pass developers to redeem passes. An Issuer account can have only one Collector ID.\n"]]
