Patent number: 11775957Abstract: A payment reader can have one or more kernels capable of performing certain payment processing functions but not capable of performing certain, more processing-intensive payment processing functions. The payment reader may be designed to selectively assign processing tasks to application layer kernels located on a mobile device and/or a cloud-based device external to the payment reader, the mobile device having more or different processing resources than the payment reader. The selective assignment may be made dynamically based on the measurement of a condition of the reader or an occurrence of an event, such as a determination that the payment reader cannot process a transaction, that the payment reader does not have sufficient battery strength to process the transaction, or that there has been a tampering attempt at the payment reader. The payment reader also has a physical layer module, which module maintains its processing on the payment reader.Type: GrantFiled: May 27, 2021Date of Patent: October 3, 2023Assignee: Block, Inc.Inventors: Murat Cat, Gokhan Aydeniz, David Terra

Publication number: 20200410477Abstract: A payment terminal includes multiple chips that perform different processing functions within the payment terminal. A terminal chip performs general functionality of the payment terminal while a transaction chip communicates with payment devices such as chip cards and NFC payment devices and processes payment information. The transaction chip may operate in a low power during which communications and processing are limited, and a transaction processing mode in which transactions may be processed. The transaction chip may transfer between these modes based on wake-up messages provided by other devices or circuitry of the payment terminal.Type: ApplicationFiled: September 10, 2020Publication date: December 31, 2020Applicant: Square, Inc.Inventors: David Terra, Koun Han, Michael Wells White, Michael Dahn

Patent number: 10255464Abstract: A payment terminal such as a payment reader may receive and form electrical connections with an electronic transaction card such as an EMV chip card. The payment terminal may provide a clock signal at a rate that exceeds a specified rate for the EMV chip card. The payment terminal may transmit messages to the EMV chip card and monitor receive messages at a data connection. The payment terminal may determine that the clock rate is excessive based on a timeout of a receive message, an error rate of a receive message, or a receive message indicating that one of the transmit messages was not received by the EMV card. The payment terminal may reduce the clock rate to a rate that is below the specified rate for the EMV chip card.Type: GrantFiled: November 28, 2017Date of Patent: April 9, 2019Assignee: Square, Inc.Inventors: David Terra, Ross Glashan

Patent number: 10163107Abstract: In some examples, methods and systems may institute technical fallback by determining, by a payment processing system, and based on analysis of the communication status indicator and the data obtained when a magnetic stripe of the payment object is introduced in magnetic stripe object reader, whether the payment object was swiped while an EMV object reader was communicatively coupled to the POS terminal. If the magnetic stripe of the payment object was swiped while the EMV object reader was connected to the POS terminal, the payment processing system extracts a transaction count indicating a number of times the customer has attempted to insert a chip of the payment object into the EMV object reader prior to swiping magstripe. By comparing the transaction count with a threshold count, the payment processing system authorizes the payment transaction as a technical fallback transaction if the transaction count is greater than the threshold count.Type: GrantFiled: March 31, 2016Date of Patent: December 25, 2018Assignee: Square, Inc.Inventors: Michael Wells White, Jason Holmes, Martin Mroz, David Terra, Charles Nicholson

Patent number: 10120427Abstract: A payment reader includes a power management system to control the power mode of the payment reader. The power management system can transition the payment reader between a sleep mode, a low power mode and a full power mode. The power management system can use a low power mode reference counter to determine when to transition from the full power mode to the low power mode and a sleep mode reference counter to determine when to transition from the low power mode to the sleep mode. When the low power mode reference counter reaches zero, the power management system deactivates a payment processing subsystem to transition to the low power mode. Similarly, when the sleep mode reference counter reaches zero, the power management system deactivates a payment reader system to transition to the sleep mode.Type: GrantFiled: March 30, 2016Date of Patent: November 6, 2018Assignee: Square, Inc.Inventors: Nicholas Hebner, David Terra, Rodion Steshenko
