Abstract: In some embodiments, a mobile cash change processing system for processing cash change to be returned to a user in return for cash payment transaction executed at a retailer location includes a server remotely operable to execute electronic monetary transactions between digitally stored accounts and having stored in association therewith: user account data associated with each of a plurality of registered user accounts; retailer account data associated with each of a plurality of registered retailer accounts; and sharing account data associated with each of a plurality of registered sharing accounts. The system further includes a digital mobile application operable on the user's mobile device to: invoke communication of a cash change return identifier to said server, receive identification of a sharing account associated with the retailer location; display a selectable sharing option to the user; and communicate user selection to said transaction server to invoke an electronic transfer of funds.

Abstract: A system and method for aligning tile images of an area of interest of an integrated circuit having N metal layers M, where N>1, includes a parametric representation algorithm for extracting parametric representations of edges from an image showing metal layer (MN) and at least a proportion of metal layer (MN?1) of the integrated circuit to produce a parametric representation of the edges visible on the respective metal layers. The parametric representations include an indication of the metal layer with which each extracted edge is associated and at least one of x and y coordinates associated with each of the extracted edges.
