Restaurant POS Access Control Should Govern Actions, Not Job Titles

Cashiers, kitchen staff, managers, and owners all need different levels of access to a point-of-sale system. The article argues that a role name alone is not a sound security rule, proposing instead that permissions represent specific capabilities such as creating orders, managing tables, or processing refunds. Roles are presented as bundles of these permissions, which can be individually adjusted to handle real-world exceptions. The author stresses that the backend must enforce these checks on every protected action, since hiding interface buttons does not prevent unauthorized access. Finally, the piece cautions that overly granular permission lists can become hard to understand, recommending clearly named permissions and auditable changes.
