1. Use the inpatient, outpatient and physical examination records of the insured to judge whether the insured has any past diseases and whether to tell the truth.
2. The social security or medical insurance card record of the insured.
3. The claims records of other insurance companies, and some insurance companies have the same claims data. You can check whether the insured has ever been refused insurance or made claims. Claim settlement is the concrete embodiment of insurance companies' execution of insurance contracts, fulfillment of insurance obligations and assumption of insurance liabilities. On the one hand, only by doing a good job of claim settlement can the insured's losses be properly compensated and the function of insurance be brought into play.
