Wikipedia states that "Most e-gates (automated border control systems) have been deployed in airports in Europe, Australia and Asia." Are there any land border crossings that rely on automated gates in part or entirely?
All Singapore - Malaysia land borders relies on automatic gates for residents and for people leaving the country (Singapore side). Visitors will still have to convince border agents to let them in. And residents have fallback on using the agents, if they want.
The Spain/Gibraltar border has a row of automated gates (they can be seen in this video) that scan identity documents for those exiting and entering Spain. The Gibraltar authorities have their own checkpoint entering as well.
They do not rely entirely on the automated gates. When I visited, as a non-EU national, they just waved me through the side door around the gates.
Brazil has some automated gates in Guarulhos International Airport and Viracopos International Airport (Campinas).
You can use if you are a Brazilian Resident and you do not have any minor with you.
I am not sure, but the same approach could be used in other places in Brazil.
Brazil’s Viracopos International Airport, which serves Campinas, São Paulo, has implemented automated border control e-gates, which make use of facial recognition technology to secure the border control process and create a more seamless passenger experience.
The system, which has been implemented by Vision-Box, compares the image stored in the chip of the passenger’s passport to a live captured image. According to the vendor, the e-gates reduce the time taken to clear border control from three minutes to around 15 seconds.
President & Director of Viracopos International Airport, Gustavo Müssnich, said: “After Viracopos reached a record in passenger volume in a single year (10.3m in 2015), this new technology has arrived to make the airport journey much more seamless and secure.”
Leidivino Natal da Silva, General Director of Vision-Box Latin America, explained that the system will help the airport to optimise passenger flow.
“One of the trends of special interest in the aviation industry is currently to refine security processes in order to increase reliability and sustainability,” he explained. “Viracopos International Airport is highly aware and decided to focus on the solution that brings higher levels of innovation and orientation to passenger experience.”
