A computer system can implement a network transaction service by monitoring location data from a computing device of a user to confirm that the user is located at a merchant location, receiving transaction data from a point-of-sale terminal of the merchant location, and confirming that the user has left the merchant location based on the location data. The computer system may then automatically execute a transfer operation to fund the transaction using a shared funding account of the network transaction service such that no direct payment interaction is made between the user and the merchant. |

System and method for managing customer call-backs
A system herein provides automated call-back of customers who have terminated an inbound call by exercising a call-back option of an interactive voice response unit or by abandoning the inbound call, using predictive modeling of caller value to prioritize call-backs. The call management system monitors the inbound customer call and detects any termination of the customer call. A call-back module opens a call-back record for the terminated customer call and associates that call-back record with an identified customer. The call-back module retrieves customer demographic data and other data associated with the identified customer. A predictive module determines a value prediction signal for the identified customer by modeling purchase and lapse behaviors and classifies each identified customer for either priority call-back or subordinate call-back treatment. Priority call-back classification may result in assignment to a priority call-back queue, assignment to a priority call-back queue position, or call-back by a selected agent. |

Device, system, and method for card skimming protection
A card reader's motorized transport is controlled by firmware of the reader so as to control a distance that any card can be pulled into the reader during a transaction on a host device.

Furthermore, the entire length of the card is prevented from completely passing over the magnetic read interface during the transaction such that any skimmer placed within the reader is physically unable to read the magnetic card information from the magnetic strip of the card. In an embodiment, the firmware is configured to permit only chips from the cards to be read for transactions or configured to turn off chip only reading by permitting both chip reads and magnetic strip reads for each transaction. |
