[0002] In the field of payment, emerging payment methods are constantly emerging, personal portable payment is already a hot topic in future electronic payment, and the application scenario scheme for traditional protection of POS equipment is slightly single; this requires the expansion of application scenarios for traditional payment equipment We cannot rest on our laurels. In order to meet the requirements of the times and the integration of new technology products, POS equipment application solutions need to constantly innovate and closely integrate with the times to keep up with the pace of the times.
[0003] If you use a data cable to connect the Apple device to the POS device for communication, the POS device will draw a large current from the Apple device, reducing the use time of the Apple device itself, and the current design of the Apple device data cable does not allow an external power supply to charge the device. Due to the design of the Apple device, it cannot be charged when the Apple device is connected to the POS device

Abstract
The invention provides a data line circuit communicating with Apple equipment. The circuit comprises a first connector circuit, a second connector circuit and a power supply end selection circuit, wherein the power supply end selection circuit comprises an auxiliary power input interface, a first power supply interface, a second power supply interface and a power supply input interface; the firstconnector circuit comprises an equipment charging interface and a slave equipment charging interface, the equipment charging interface is connected with the first power supply interface, and the slaveequipment charging interface is connected with the auxiliary power input interface; the second connector circuit comprises a charging interface, and the charging interface is connected with a secondpower supply interface of the power supply end selection circuit. According to the data line circuit communicating with the Apple device, when the Apple device is connected with the slave device, external power can be accessed to supply power to the Apple device and the slave device, and the standby time is prolonged.
