How is proof of certification typically verified?

When verifying proof of certification, in-person inspection of certification cards is certainly an effective method. This approach ensures that the actual physical card, which typically includes secure features such as a hologram or unique serial number, is presented and examined. Personnel responsible for verification can visually confirm the authenticity of the card, thus minimizing the risk of accepting a counterfeit or expired certification.

Other methods, while possible, may not offer the same level of security and verification assurance. For instance, submitting a certification form may not provide immediate confirmation of the cardholder's qualifications and could be subject to errors or falsification. Presenting a successful completion document can validate that an individual has completed training, but it doesn't necessarily prove that they are currently certified. Online verification could be convenient, but it relies on digital records that might not be fully secure and could be susceptible to unauthorized alterations. Thus, in-person inspections serve as a robust means of ensuring that a certification is legitimate and current.
