Miami International Airport has replaced manual passport checks for international arrivals with a facial recognition system that matches each traveler's face against government passport and visa photos. The system, operated by U.S. Customs and Border Protection through its cloud-based Traveler Verification Service, aims to meet a federal mandate for biometric entry and exit while moving people through customs faster.
MIA serves as the primary U.S. gateway for flights from Latin America and the Caribbean. The Miami-Dade Aviation Department partnered with CBP to install the biometric gates, though the specific vendor contracted for the MIA deployment has not been disclosed. The initiative had been rolled out at other U.S. airports before reaching Miami, and as of late 2024 it remained operational at MIA.
The legal authority comes from a federal requirement that CBP collect biometric entry and exit data on foreign nationals. U.S. citizens are not legally required to participate. Travelers who decline the scan proceed through a separate manual lane, though the opt-out procedure at MIA at launch remains undocumented.
How the System Works
When an international passenger approaches the customs checkpoint at MIA, a camera captures a live photo. That image travels to CBP's Traveler Verification Service, which compares it against a gallery of passport and visa photos stored in government databases. A match clears the passenger. No match triggers a manual identity check by a CBP officer. The whole process lasts seconds.
The matching occurs on CBP's cloud servers, not on hardware at the airport. CBP says it does not store the live photo unless a match fails; that image may be retained for investigation. The agency has not published a data retention period for the MIA deployment. Advocacy groups warn that the absence of a firm retention policy could seed a permanent facial recognition database of travelers.
Foreign nationals face the biometric collection requirement under immigration law. U.S. citizens can request an alternative screening process, though how visible and available that alternative was during MIA's initial rollout remains unclear in public records.
Scope of the Rollout at MIA
It is not clear whether biometric screening covers all international arrival terminals or only selected gates. MIA operates multiple concourses for international flights, and CBP has deployed the Traveler Verification Service at some but not all of them. The first airlines integrated into the system at MIA have not been named.
MIA's role as a hub for Latin American and Caribbean carriers means a large share of arriving passengers are foreign nationals, the primary targets of the federal biometric exit mandate. U.S. citizens arriving from those regions pass through the same gates but can opt out. The Miami-Dade Aviation Department has released no data on total throughput or the number of travelers who chose manual screening.
The operational timeline for MIA is also undocumented. CBP has been rolling out biometric entry systems across U.S. airports since 2018, and MIA joined that list sometime before late 2024. The absence of a vendor name is unusual for a project of this scale; at other airports, CBP has contracted with SITA, Idemia, or NEC for similar deployments.
Privacy Concerns and Regulatory Response
Advocacy group objections
The Electronic Privacy Information Center and the American Civil Liberties Union have argued that the initiative operates without adequate congressional oversight and that the agency has not explained how long it retains biometric data. A central concern: a photo supplied for a passport is being repurposed for real-time surveillance without the traveler's explicit consent.
Congressional scrutiny
In 2020, members of the House Homeland Security Committee asked CBP to provide false match rates and opt-out rates across all airports. The agency has not released airport-specific figures for MIA. CBP maintains that the facial matching is accurate and that it compares photos only against travelers on the arriving flight, reducing the chance of a false match.
Legal standing
No class-action lawsuit has targeted the MIA deployment. The initiative continues under the same legal framework used at other airports. No federal court has ordered a halt to biometric screening at U.S. ports of entry.
Performance Claims and Measured Outcomes
Wait times
CBP says biometric entry shrinks time at the customs checkpoint, though no wait-time reduction percentage has been published for MIA. At other airports where the matching system runs, the agency reports the facial recognition step takes under 20 seconds. Total time saved depends on how many manual lanes stay open and how many passengers opt out.
Identity fraud
The initiative's stated goal is stronger security: ensuring the person presenting a passport matches the biometric data on file. CBP says the system has flagged impostors at other airports when the live photo diverged from the passport photo. No detection figures have been reported for MIA.
Market impact
For operators and investors watching the airport technology sector, the MIA deployment illustrates how a federal mandate drives large-scale facial recognition adoption. The missing vendor name and absent performance data make it impossible to identify which supplier benefited. The program remains ongoing, and as of late 2024 no further details have emerged.

- Status: Ongoing as of October 2024
Frequently Asked Questions
Is biometric screening mandatory at Miami International Airport?
Foreign nationals must provide biometric data under immigration law. U.S. citizens can request alternative screening, though the availability of that option at MIA during the initial rollout is not documented.
What happens to my photo after I am screened?
CBP states the live photo is not stored unless a match fails. If the system cannot match the traveler, the image may be retained for investigation. The agency has not published a data retention period for MIA.
Which vendor provided the facial recognition technology for MIA?
The vendor at MIA has not been disclosed. At other airports, CBP has worked with SITA, Idemia, and NEC.
