Abstract: Methods and systems for retaining credit card usage through systematic recognition of recurring payments are described. In some embodiments, a method includes receiving user transaction data relating to a payment instrument issued to a user. The user transaction data may include payees and a schedule of payments to the payees. The method may further include identifying recurring payees based on a category of each of the payees. In response to a triggering event requiring an account update of the payment instrument, a report identifying the recurring payees may be generated for the user.

Abstract: Techniques are described for automatically presenting workflow(s) in an application based at least partly on detected signal(s). A radio-frequency signal may be emitted from a transceiver included in, attached to, or otherwise associated with a payment card. The signal may be received by a transceiver of a user device when the card is in proximity to the device and, in response, an application may launch a workflow including one or more pages of content in the application. The launched workflow may include functionality for activating a payment card, based on a determination that the card is not yet activated. The launched workflow may also include functionality for viewing account information, based on a determination that the card is already activated.

Abstract: Method and apparatus for use with a probe beam and detector for detecting the presence of a target analyte in a sample. The apparatus includes a substrate; and a biolayer located on the substrate designed to react to target analyte when the sample is deposited on the biolayer. The substrate can be selected to substantially minimize reflectance by the substrate while substantially maintaining scattering by the target analyte. The substrate can be designed so waves reflected by the substrate are substantially in quadrature with waves scattered by target analyte; or so waves reflected by the substrate and scattered by target analyte interfere in the far field and directly create intensity modulation detectable by the detector. The biolayer can include a plurality of spots, and the spots can be grouped into unit cells having specific antibodies and non-specific antibodies for reacting with target analyte.
