Near field communication and two-dimensional code compatible device and method

Abstract

The invention relates to a near field communication and two-dimensional code compatible device and method. The device comprises a two-dimensional code recognition module used for scanning a two-dimensional code so as to obtain two-dimensional code information; a near-field identification module used for performing near-field communication with a target object to obtain near-field information; a distance sensor used for detecting the distance of the target object; and a processor used for starting the near-field identification module to obtain the near-field information when the distance detected by the distance sensor is smaller than a distance preset value. The near field identification module is started only when the distance of the detected target object is smaller than the distance preset value. Therefore, the two-dimensional code scanning process is prevented from being interfered by starting the near-field recognition module at a relatively long distance, so that the two-dimensional code reading head of the two-dimensional code recognition module and the card swiping reading head of the near-field recognition module can be arranged in a relatively short distance range, and the purpose of miniaturization of the device is achieved.

Description

technical field [0001] The invention relates to the field of information acquisition, in particular to a device and method compatible with near-field communication and two-dimensional codes. Background technique [0002] The statements in this section merely provide background technical information related to the disclosure of the present invention, and do not necessarily constitute prior art. [0003] At present, such products on the market that support both card swiping and QR code functions (such as bus barcode readers that support mobile phone QR code payment in various places) adopt a separate design scheme: that is, the QR code reader and the card reader Separate, at least in terms of distance to ensure that the NFC signal will not activate the NFC function on the phone (above 5cm), which will cause the whole machine to be large and bulky.

Problems solved by technology

[0003] At present, such products on the market that support both card swiping and QR code functions (such as bus barcode readers that support mobile phone QR code payment in various places) adopt a separate design scheme: that is, the QR code reader and the card reader Separate, at least at a distance to ensure that the NFC signal will not activate the NFC function on the phone (above 5cm), which will cause the whole machine to be bulky and bulky

There are big flaws in the product installation layout, and a cable needs to be pulled in the middle to connect the two devices, so that the reliability of the product cannot be guaranteed; in terms of product shape and function, it cannot meet most application scenarios

[0004] However, if the two-dimensional code reader and the card reader are integrated together, under normal use, because a large number of mobile phones support the NFC function, it is easy to wake up the NFC payment interface when scanning the two-dimensional code function, resulting in two-dimensional display of the mobile phone screen. The two-dimensional code interface jumps to the payment interface, so the two-dimensional code interface is blocked by the NFC payment interface and cannot be scanned
