Final answer:
If a RAIC Reader displays "RAIC NOT VALID", it indicates that the card is not recognized as active or valid within the system, often leading to denied access and requiring the cardholder to seek assistance.
Step-by-step explanation:
If the portable RAIC Reader states "RAIC NOT VALID", it implies that the Restricted Area Identity Card (RAIC) being read is not recognized as a legitimate card within the system's database or is not currently active.
This can occur for several reasons, such as the card being expired, reported lost or stolen, or the individual's access rights have been revoked. In sensitive areas, particularly in airports or other security-relevant zones, maintaining valid RAIC is crucial for ensuring only authorized individuals gain entry. When such a message is displayed by a RAIC Reader, the standard protocol is usually for the individual to contact security or the issuer of the RAIC for further assistance in resolving the issue.
