Abstract: A user takes a photo of a payment recipient using the user's mobile device. The photo is analyzed to determine whether a matching photo with an identifier exists, such as on the user device or within a payment provider database. If so, the identifier is used to identify the recipient and process a payment from the user to the recipient.

Abstract: The present invention relates to electrically conductive polymer compositions, and their use in electronic devices. The compositions contain a semi-aqueous dispersion of at least one electrically conductive polymer doped with at least one highly-fluorinated acid polymer, non-conductive oxide nanoparticles, at least one high-boiling organic liquid, and at least one lower-boiling organic liquid.

Abstract: Systems and methods are provided for efficient transactions according to one or more embodiments. According to an embodiment, a method for efficient transactions comprises associating an identifier to a seller, wherein the identifier is adapted to in turn be provided to a user in connection with one or more transactions at a point of sale (POS) location, and wherein the identifier is mapped to particular identification information of the seller at a remote location. The method also comprises receiving, at the remote location, input from a user device upon the user selecting the user device in connection with the one or more transactions, wherein the input includes the identifier and is made at the POS location. Furthermore, the method comprises facilitating the one or more transactions based on the received input including the identifier that is mapped to the particular identification of the seller.

Abstract: Chemical species (e.g., metaborate, carbonate, hydroxide and sulfide) in a boron-containing alkaline wood pulping liquor sample are determined quantitatively by (i) subjecting a first aliquot portion of the sample to a primary acid titration analysis to derive multiple equivalence points at different respective pH values; (ii) subjecting a second aliquot portion of the sample to an analysis to determine the quantitative presence of boron or sulfide ions therein, and then (iii) determining the quantitative presence in the sample of at least one of the chemical species. Wood pulping parameters may thus be determined on the basis of the quantitative presence of the chemical species to assist in process and/or quality control of the wood pulping operation.
