In one embodiment, a system comprises a plurality of electronic circuit boards and at least one optical fiber in optical communication with at least one circuit board of the plurality of electronic circuit boards, wherein at least one optical fiber comprises at least one core having at least one end surface, and wherein at least one end surface comprises a light dispersing geometry. The primary games may be played simultaneously. Next, forming a connected device in the insulating layer to connect with the first conducting line layer. During the transaction, the computer system may identify a second substance forming part of the purchase transaction. Optionally, the material of the optically active coating is index matched to the light transmissive substrate in order to optically erase the effect of the surface relief pattern in the portions of the surface relief pattern not covered by the reflective material. The seal cup includes an external circumferential seal land adjacent the cup lip and an outer surface capable of permitting drainage away from the seal land of fluids, which may seep past the seal land.
