Identity devices including radio frequency shielding

Abstract

Shielding is associated with RFID tags to achieve new systems and methods having various advantages. These systems include containers configured to store RFID enabled identity documents, the use of RFID tags to monitor the state of a container, and the inclusion of shielding in identity devices. Disclosed are shielded passports, driver's licenses, and the like. Some embodiments further including reading systems for reading identity devices comprising shielding and RFID tags.

AI Technical Summary

Benefits of technology

[0023] Various embodiments of the invention include a passport reading system comprising a first RFID reader, a second RFID reader, a third RFID reader, the first, second and third RFID readers surrounding a passport reading volume and being disposed such that at least one of the first, second and third RFID readers will be at a proper angle relative to an antenna of an RFID tag within a passport in the passport reading volume to read the RFID tag, and also disposed such that transmission between the RFID tag and the at least one of the first, second and third RFID readers is not prevented by shielding within the passport when the passport is open in the passport reading zone regardless of the angle of the shielding relative to the first, second and third readers.

Problems solved by technology

A problem with using RFID tags to store security, confidential and / or personal information is that an RFID reader can read any RFID tags that pass within its range.

Even if data is encrypted, this creates a possibility of unauthorized access to the personal data and other information stored in the RFID tag, or at the least, detection of the presence of the RFID tag.
