The use of smart border entry systems significantly increases the reliability and efficiency of borders control measures. To deal with the increasing numbers of passengers and tighter security controls, pro-active automatic decision-making support to border control authorities is needed. Modern biometric passports, also known as ePassports, integrates an electronic RFID chip into the paper document, which contains information that can be used to authenticate the identity of travelers. In this paper, an RFID-based Location Authentication Protocol, (RFIDLAP), for ePassport detection and verification is proposed. RFIDLAP is designed to detect and track ePassports in a confined area by autonomously initializing an ultra-secure access control routine between RFID tags and readers. The purpose of this protocol is to reduce the lead time for passengers at borders control areas and allow governments to process e-passports effectively without the need to increase their human resources capacity. Using C#, a simulator was developed to test the proposed protocol and the results were within 0.2% error in accuracy when processing ePassports.
