An organization finds that the amount of cash in their vending machines doesn't match the value of items sold. They have decided to upgrade their vending machines with cloud-based mobile payment…

Relaxing data access permissions would reduce security controls and has no logical connection to resolving a cash reconciliation problem.

An error budget is an SRE reliability metric unrelated to financial transaction discrepancies in vending machines.

Perimeter security refers to network boundary protection and is not a benefit gained by upgrading to cloud-based mobile payments.

Cloud-based payment systems automatically log every transaction in a retrievable data history, allowing the organization to audit and reconcile sales against cash at any time. This directly addresses the discrepancy problem by replacing untracked cash exchanges with timestamped digital records. The ability to query historical transaction data is a core operational benefit of cloud-connected point-of-sale systems.
