The new European Entry/Exit Scheme (EES) gathers biometric data on citizens arriving in the EU from non-member, third-party countries, which includes the UK.
After technology delays, it is now due to roll out in October 2025.
"The EU is introducing this new entry and exit scheme so nothing is going to happen before that's in place, and that's not yet in place. They've put the date back for that a few times, the latest date is the autumn, let's see if that's stuck to.
"After that it's up to the member states. But this gives us the possibility, I'd say the probability, that people will be able to use the e-gates in future, which is not a possibility at the moment," McFadden added.
