# §101.520. Electronic TWIC inspection.


To conduct electronic TWIC inspection, the owner or operator of a vessel or facility must ensure the following actions are performed.

- (a) **Card authentication.** The TWIC must be authenticated by performing a challenge/response protocol using the Certificate for Card Authentication (CCA) and the associated card authentication private key stored in the TWIC.
- (b) **Card validity check.** The TWIC must be checked to ensure the TWIC has not expired and against TSA's list of cancelled TWICs, and no match on the list may be found.
- (c) **Identity verification.**
  - (1) One of the biometric templates stored in the TWIC must be matched to the TWIC-holder's live sample biometric or, by matching to the PACS enrolled reference biometrics linked to the FASC-N of the TWIC; or
  - (2) If an individual is unable to provide a valid live sample biometric, the TWIC-holder must enter a Personal Identification Number (PIN) and pass a visual TWIC inspection.
