"We're employing existing and proven technologies – as well as novel ones – to empower border agents to increase the accuracy and efficiency of border checks," said project coordinator George Boultadakis of European Dynamics Luxembourg in an article posted on the European Commission's website. The technologies utilised include an automatic deception detection system, biometrics verification (fingerprinting and palm vein scanning), face matching, document authentication and a hidden human detection tool. Additionally, integrated border control analytics, risk-based assessment, and a system used to cross-check travellers' information from social media or legacy systems are also being employed. As stated on the project website, iBorderCtrl will use these technologies to "collect data that will move beyond biometrics and onto biomarkers of deceit."

Before arriving at the border, travellers register and upload all relevant travel documentation through an online system using their mobile phone, tablet or computer. Travellers are then asked a series of questions by an avatar and their non-verbal micro-expressions are analysed to determine whether they are lying or not. To improve the system's accuracy, the avatar is personalised to match the traveller's gender and language. Potentially illegal crossings are flagged so that border guards can conduct more detailed checks.
