A method of processing a deposit transaction involving a plurality of physical documents includes receiving a data file associated with the deposit transaction. The sensor chip achieves SPR through a grating-coupled approach, with variations in the local dielectric constant at regions of interest at the sensor surface detected as a function of the intensity of light reflecting from these ROI. 5 \u03bcm, and at least 80% of number of the fine inorganic compound particles contains no strong acidic component shows a high light-scattering property and gives no harmful effect to human body. An arm moves a cartridge from the hub to the chamber. A reflective coating may then be applied to the last applied and cured resin layer.
