Access follows ownership.
The security model begins with verified identity and current authority, then narrows to the requested operation.
Identity and permission are different checks.
First-party web services verify the user session; mobile services verify bearer credentials. Business authority is read from current membership and role, not accepted merely from client state. Personal operations check account ownership. Sensitive modules add live-session, origin, assurance or bounded-request checks as applicable.
The intended evaluation tenant must demonstrate denied cross-organization access, revoked permissions and disabled capability behavior. Source controls need runtime acceptance; this page does not claim that every deployed setting has been verified.
Sensitive card details belong with the issuer.
Card-provider foundations separate summary/control data from sensitive details. The intended integration opens issuer-hosted short-lived detail surfaces on the cardholder’s device rather than returning PAN, CVV or PIN through ordinary Peyeli records. This boundary requires provider acceptance and a reviewed program.
Evaluate the whole boundary.
Agree on who approves access, how it expires, how revocation is verified, and what happens during an incident. Public documents describe the model; account-specific evidence and confidential security questions belong in an approved review channel.
