A rounded card outline with a real lanyard slot cut into the top edge, extruded 0.01 m thick. The chip is a rounded gold pad with three contact ribs, a lit strip crosses the upper right, a dark magnetic band runs across the back and a violet arrow shows which way it goes into the reader. No lettering of any language appears on it. Bounding size 0.34 by 0.22 by 0.02 m; metres, +Y up, +Z forward. Origin: free, at the centre of the card, on the spin axis, because a collectible like this is hung in mid-air at whatever hover height the level needs and a base origin would put it on the floor. The geometry surrounds the origin, reaching 0.110 m below it and 0.110 m above it. Clips: bob (2.2 s), spin (2.0 s). Rigid node animation only: named nodes with translation, rotation and scale clips, no skinned rig and no skeleton. No collision volumes and no navigation data. Opaque materials throughout; the pack uses no alpha blending and no transmission.
