Patent number: 9424721Abstract: A point-of-sale system includes a stand that supports a tablet computer. The tablet computer can run a merchant application to provide the typical functionality for a point-of-sale system. The stand can be rotatable to face either the merchant or the customer. The stand can incorporate a card reader. The tablet computer can be connected through a hub to other peripheral components, such as a controllable cash drawer, a printer and/or a bar code reader. The cash drawer can include a slidable drawer having sliding rails that are hidden from a top view of the drawer.Type: GrantFiled: March 12, 2013Date of Patent: August 23, 2016Assignee: Square, Inc.Inventors: Troy Edwards, Lukas Skoog, Amish Babu, Jesse Dorogusker

Publication number: 20160203667Abstract: A card reader is provided with a read head with a slot and is configured to be coupled to a mobile device and has a slot for swiping a magnetic stripe of a card. The read head reads data on the magnetic stripe and produces a raw magnetic signal indicative of data stored on the magnetic stripe. A power supply is coupled to wake-up electronics and a microcontroller. An output jack is adapted to be inserted in a port of the mobile device and deliver an output jack signal to the mobile device. The wake-up electronics is powered by a microphone bias of a mobile device.Type: ApplicationFiled: February 2, 2016Publication date: July 14, 2016Inventors: Kartik Lamba, Amish Babu, Michael Shyh-yen Ho, Adam David Peter Rothschild, Gerald Thomas Ryle, Jack Dorsey, James M.

Publication number: 20160203466Abstract: A method is provided of transmitting information with a communication protocol to a mobile device. A card reader is provided with a read head that has a slot for swiping a magnetic stripe of a card, an output jack and device electronics that includes a microcontroller. The read head is used to read data on a magnetic stripe of a card. A raw magnetic signal is produced indicative of data stored on the magnetic stripe. The raw magnetic head signal is converted into a processed digital signal that the microcontroller can interpret. A synchronous Manchester encoded stream is produced that makes a greater number of 0 crossings. A Manchester encoded stream output jack signal is delivered to the mobile device through the output jack.Type: ApplicationFiled: February 2, 2016Publication date: July 14, 2016Inventors: Kartik Lamba, Amish Babu, Michael Shyh-yen Ho, Adam David Peter Rothschild, Gerald Thomas Ryle, Jack Dorsey, James M.

Patent number: 9058727Abstract: A point-of-sale system includes a stand that supports a tablet computer. The tablet computer can be connected through a hub to other peripheral components, such as a cash drawer. The cash drawer can include a slidable drawer including a front face, a back face, a first side face, a second side face, and a bottom face and having sliding rails that are hidden from a top view of the drawer. An inner shell is attached to the drawer and two sliding rails, the two sliding rails positioned under the inner shell. Further, a latch is movable between a first position in which the latch holds the drawer in a closed position and a second position in which the latch releases the drawer to an open position. An actuator is used to move the latch between the first and second positions.Type: GrantFiled: March 13, 2013Date of Patent: June 16, 2015Assignee: Square, Inc.Inventors: Troy Edwards, Lukas Skoog, Amish Babu, Jesse Dorogusker, David Craig
