This disclosure relates to systems and methods for processing electronic payments for customer purchases. In some implementations, a mobile computing device receives a payment request identifying a sales transaction between a merchant and a customer. The payment request indicates a purchase amount owed by the customer to the merchant, and carries a set of instructions. The mobile computing device activates a card reader based at least in part on the set of instructions, receives customer authorization for electronic payment of the purchase amount, instructs the card reader to process a credit card for the purchase amount based on receiving the customer authorization, and receives confirmation of payment of the purchase amount from the card reader.

A key entry device including a housing, a keypad array disposed within the housing and including a plurality of keys, a key contact array disposed within the housing below the keypad array and including a plurality of contact pairs, a dome array underlying the keypad array and the key contact array and including a plurality of domes, and a protrusion array underlying the dome array and including a plurality of protrusions, whereby depression of one of the plurality of keys of the keypad array causes a corresponding one of the domes of the dome array to be displaced downwardly and to be deformed by pushing engagement with a corresponding one of the protrusions of the protrusion array into contact with at least one of the contact pairs of the key contact array.

A mobile terminal assembly and a mobile terminal are disclosed. The mobile terminal assembly may include a housing, a card holder assembly and a first antenna module. The housing is provided with a card slot; the card holder assembly is located at the card slot and is configured to carry a memory; and the first antenna module is installed in the housing. The first antenna module is configured to be switched between a first position and a second position under the action of an external force. When the first antenna module is located at the first position, the card holder assembly is located in the housing, and the first antenna module is located between the card holder assembly and the card slot; and when the first antenna module is located at the second position, the holder assembly at least partially passes through the card slot to extend outside the housing.

An apparatus is described. In an embodiment, the apparatus comprises a housing; a tray; an ejector; a push member having two positions, the push member is configured to receive an external force for moving the push member and to operate the ejector to eject the tray to an ejected open position when the push member is moved to a second position and to maintain in the second position; and a switch comprising two electric position; the switch is configured to switch to a first electric position when receiving the external force, and the push member is configured to maintain the switch in the first electric position when the push member is moved to the second position causing the tray to eject; when the tray is returned to a retracted closed position, the push member is moved to a first position causing the switch to switch to a second electric position.

Aspects of the technology provide a card reader for facilitating a financial transaction between a buyer and a merchant. In some implementations, the card reader includes an audio plug configured to provide a communicative coupling between the card reader and a smartphone device, and a read head communicatively coupled to the audio plug, the read head being configured to read financial information from a payment card for processing a transfer of funds from the buyer to the merchant. In certain implementations, the card reader further includes a switch coupled to the audio plug, wherein the switch is configured to close in response to the presence of the payment card to enable communication between the card reader and the smartphone via the audio plug.

A card insertion unit is provided, which prevents the mixture of lights in different colors even with light sources to emit lights in different colors at the periphery of a card insertion slot. A card insertion unit, having a card insertion slot through which a card is inserted, includes: a plurality of light sources provided to surround the card insertion slot, when viewed in an insertion direction of the card, with a light emitting unit facing in a direction opposite to the insertion direction so as to each emit lights in multiple colors; a translucent cover member that is provided with the card insertion slot and is overlapped with the light sources in the direction opposite to the insertion direction; and a reflective member provided between the light sources and the card insertion slot to reflect light that is to travel from the light sources toward the card insertion slot.

An automated, dynamic digital financial management tool is described herein. The financial management tool enables a user to access all forms of payments, debt and transactions to be deducted automatically depending on which form of payment is chosen. The financial management tool documents every item/service purchased. The documentation enables a company/manufacturer/store to provide marketing and recall information to the user. The financial management tool is able to include any and/or all financial aspects of a user's life. The financial management tool is able to be implemented using a universal card. The financial management tool is able to include a pay station to receive payments. The financial management tool is able to include automated services.

A payment terminal evaluator includes a contact structure and a card structure. The contact structure intersects a rectangular space such that part of the contact structure is within the rectangular space and part of the contact structure is outside of the rectangular space. The card structure extends from the contact structure and is positioned entirely within the rectangular space. The card structure includes a top surface, a bottom surface, a first side surface between the top surface and the bottom surface, a second side surface between the top surface and the bottom surface, a first tab defined in part by the top surface, the bottom surface and the first side surface, a second tab defined in part by the top surface, the bottom surface and the second side surface, and an opening between the first tab and the second tab.

Some embodiments include a smart card reader system that includes a card reader cavity that is impervious to liquid. The card reader cavity includes a secure card reader (SCR) holder bonded to a printed circuit board (PCB), to provide a liquid barrier between the SCR holder and the PCB. The PCB includes an SCR spring contact connector. The card reader cavity can receive a smart card including an integrated circuit (IC), where the IC is coupled to the SCR spring contact connector. A processor coupled to the SCR spring contact connector, can receive an input regarding a transaction using data of the smart card, and execute the transaction. In some embodiments a roller system seals the card reader cavity when the smart card reader system is not in use.

This document describes apparatuses that include integrated memory card ejector and sensor ports. A first described aspect of an apparatus includes a memory card connector, a housing, and a carriage. The memory card connector includes a receiver configured to receive a memory card and an ejector assembly configured to eject the memory card from the receiver. The housing includes a sidewall that includes a memory card slot and an integrated port. The integrated port defines an outside opening of the housing. The carriage includes a slide portion slidably positioned in the integrated port and is accessible through the outside opening of the housing. The carriage includes a carriage body having an outer port, a sensor port, and an acoustic chamber defined within the carriage body. The carriage includes an ejector connector configured for contacting the ejector assembly and a sensor assembly mounted on the carriage at the sensor port.
