A charge relay enhancer used in relaying a charge produced in a solar cell to a charger, and a solar cell system including the charge relay enhancer. The charge relay enhancer includes: a charge induction and pumping device inducing a charge by using a power voltage from among two power voltages of different polarities selected in response to a control signal, and pumping the induced charge; and a charge pathway selecting device relaying the charge input to an input terminal via two input/output terminals, to the charge induction and pumping device, receiving the charge pumped by the charge induction and pumping device via the two input/output terminals, and outputting the charge to an output terminal. Accordingly, as charges produced in a solar cell may be relayed to a charging device as much as possible, efficiency of relaying charges produced in the solar cell to the charging device may be maximized.

An improved card scanner (10) for imaging and decoding indica such as bar codes (40) on a side surface (19) of an inserted card (20). The device (10) is electrically powered and features a double scanning method using an electronic imaging element (31) and processor which turns off unnecessary power when not required. This is accomplished through the use of a processor and software to determine if a complete image of the bar code (40) on the inserted card has been captured and allowing immediate removal of the card (20). Should the image of the bar code (40) be incomplete, a second scan is conducted of the bar code (40) as it is removed and a complete image formed from the two individual scans. The device can also be used to compare photographs scanned from a card (20) with the digital photograph scanned from a two dimensional bar code (40) and to display both photos for viewing.
