1. One method involves requiring applicants to provide documentation of their income or financial need to verify genuine eligibility.
2. Another approach is to set a cap on the amount of assistance a single individual can receive.
3. Additionally, eligibility criteria can be established, such as only providing aid to those with zero or a single source of income.
These methods are commonly used. Governments typically set income thresholds for qualification, mandate proof of income, assets, and debts, and require periodic re-verification to ensure ongoing eligibility.
