PIN never stored in cloud
Execution PINs are stored encrypted on the gateway device only — never transmitted to SelfSimApp servers.
Allowlisted workflows
Only pre-approved, defined USSD/SMS flows can execute. Unknown screens trigger manual review.
Signed callbacks
All webhooks are HMAC-signed so your server can verify they came from SelfSimApp.
Role-based access
Super Admin, Business Owner, Branch Manager, Agent — each role sees and can do only what's needed.
Device-bound execution
Each task is bound to a specific paired gateway device. Rogue execution is impossible.
Transaction limits
Set daily/per-transaction limits per agent, branch, or device group to prevent fraud.
Full audit logs
Every action, task, login, and configuration change is logged with IP and timestamp.
Manual review triggers
Unusual screens or high-value transactions can be flagged for manual approval before execution.
