Abstract: An electronic device, which may be a USB device, includes a body part that is removably connected to a cap. The body part includes a connector for plugging the device into a host computing device. The cap includes a lever part and a main part. The lever part of the cap is attached to the main part and pivots at least partially around a pivot axis. The lever part includes an anchor part on one side of the pivot axis and an unlock part on the other side of the pivot axis. The anchor part includes a hook that engages a cavity in the body part when the cap is connected to the body part. Depressing the unlock part of the cap causes the lever to pivot around the pivot axis thereby disengaging the hook from the first cavity, and thereby releasing the cap from the body part.

Abstract: A secure smart card reader is disclosed that is enabled to make reader signatures on data representative of events and actions which may be security related and which may include data representative of reader commands received from a host or remote application, smart card commands exchanged with an inserted smart card, data presented to a user for approval, and/or configuration parameters applied when dealing with any of the foregoing. The smart card reader may be adapted to maintain logs of events and actions which may include exchanging reader commands, exchanging smart card commands, and/or interactions with a user. The logs may include data representative of the reader commands received, the smart card commands exchanged, data presented to the user for approval, and/or configuration parameters applied when dealing with any of the foregoing. The secure smart card reader may be adapted to generate a reader signature over the logs.
