According to one embodiment, a method for role determination includes detecting access to sensitive data and determining user information related to the access to sensitive data in response to detecting the access to sensitive data. A tray-tag of the present invention includes a face plate having front and back surfaces. The antenna assembly can also include a first connection point coupled to the opposite end of the first arm from the RF connection feed point, the first connection point being selectively coupled to an impedance. The registration posture guide includes a catalogue for each registration hand posture, where the catalogue includes a contact silhouette showing a model touch-contact interface between the display surface and that registration hand posture. The right edge of the third panel is secured to the right edge of the first panel and the left edge of the third panel is secured to the left edge of the first panel. The VCSEL comprises a substrate, a first distributed Bragg reflector, an active region, a second DBR having a non-conductive ion implantation region and a laser barrel region with a first diameter, the heavily doped semiconductor layer, and a conductive electrical contact.
