    Abstract: A payment reader and a merchant device may communicate over a wireless connection. Reliable and unreliable packets may be transmitted over a single messaging path. Each of a plurality of unreliable packet may include a data payload and a packet identifier. The unreliable packets and a reliable packet may be transmitted over the single messaging path during a first connection event. A response to the reliable packet may be received during the second event and may include a received packet listing. If the received packet listing indicates that any of the unreliable packets were not received, any unreliable packet that was not received may be retransmitted.

    Abstract: A first device and a second device may establish wireless pairing, and based on that wireless pairing, establish wireless bonding. During the wireless bonding, the two devices may have multiple connections during which information is exchanged. One of the devices may also attempt to pair with a third device. The wireless bond between the first device and the second device may be broken, and a wireless bond may then be formed with the third device.

    Abstract: 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.

    Abstract: A payment reader and a merchant device may communicate over a wireless connection. The payment reader may establish a wireless bond with a first merchant device and exchange payment information. After the payment information is exchanged, the payment reader and merchant device may disconnect while remaining bonded. The payment reader may send a request message and bond to a second merchant device, while breaking the bond with the first merchant device if a bond with the second merchant device is established. The payment reader may then exchange payment information with the second merchant device.

    Abstract translation: 支付读取器和商家设备可以通过无线连接进行通信。 支付读取器可以与第一商家设备建立无线联系并交换支付信息。 在交换支付信息之后,支付读取器和商家设备可以在保持绑定的情况下断开连接。 如果与第二商业设备的联系被建立,支付读取器可以发送请求消息并且绑定到第二商家设备,同时与第一商家设备断开联系。 支付读取器然后可以与第二商业设备交换支付信息。
