The European Union (EU) is considering further delaying the full rollout of its entry/exit system (EES) in order to avoid added complications at its borders, according to a report, The Independent reports.

The EU finally introduced its new border security system in stages from October last year, replacing the old process of manually stamping passports with the registration of biometric details when travelers arrive in Europe.

But the system has already faced calls to be scrapped after creating bottlenecks at airports.

Industry sources said that Apostolos Tzitzikostas, the commissioner responsible for negotiations over the EES with non-EU countries, has privately assured the checks will be paused.

The EU's EES only became fully operational in April and applies to all 29 Schengen countries, most of which are EU member states, with further operations expected in the autumn.

The system requires travelers to register their biometric details, such as fingerprints and a photo, when they arrive in the EU, replacing the previous system of manually stamping passports.

EES is required for all non-EU passengers entering or exiting Schengen countries.
