Abstract: A method for facilitating contactless payment at a point-of-sale is disclosed. The method includes receiving, via a terminal, a selection from a user at the point-of-sale, the selection corresponding to a payment preference; determining a transaction type based on the selection, the transaction type including a first transaction via a digital payment network and a second transaction via a mobile wallet; providing, via the terminal, transaction information and a transaction token to a mobile device that is associated with the user based on the determined transaction type; receiving, via the mobile device, a transaction request that includes the transaction information, the transaction token, and user payment information; initiating an electronic transaction based on the transaction request; and transmitting a result of the electronic transaction to the terminal and to the mobile device.

Abstract: Systems, methods, and devices for determining a contrast of colors displayed by a digital user interface are disclosed, In one embodiment, in an electronic device including a processor, a compliance module is configured to receive a user selection of a graphical element displayed on a user interface of the electronic device; determine first color data associated with a background of the selected graphical element; determine second color data associated with a text string within the selected graphical element; determine a luminosity associated with the first color data and a luminosity associated with the second color data; calculate a color contrast ratio based on the luminosity associated with the first color data and the luminosity associated with the second color data; and display, at the user interface of the electronic device, the calculated color contrast ratio.
