Abstract

The invention discloses a non-contact card chip testing device, a non-contact card chip testing method and a non-contact card chip. The testing device comprises a universal digital testing machine table, a radio frequency signal generator and a contact type bidirectional digital communication interface, the universal digital testing machine table is in communication connection with the contact type bidirectional digital communication interface, and the radio frequency signal generator is in communication connection with the radio frequency interface. The method comprises the following steps: setting a transmission mode of a test signal by arranging a contact-type bidirectional digital communication interface on a non-contact card chip, and sending a power supply and a clock signal to the non-contact card chip through a radio frequency interface; transmitting a baseband signal to the non-contact card chip through the contact type bidirectional digital communication interface; and enabling the contactless card chip to return the second data by decoding and encoding. The non-contact card chip comprises a contact type bidirectional digital communication interface which is used for transmitting baseband signals. According to the invention, the chip test efficiency can be improved, the test anti-interference capability can be improved, and the test cost can be reduced.

Description

technical field [0001] The application relates to the technical field of chip testing, in particular to a non-contact card chip testing device, a testing method and a non-contact card chip. Background technique [0002] The contactless card chip is a kind of chip that obtains power through the antenna and electromagnetic field, and communicates with the card reader. For contactless card manufacturers, in order to ensure the factory quality of the contactless card chip, it is necessary to test whether the function of the contactless card chip is normal before leaving the factory, which requires the testing equipment of the contactless card chip. [0003] The current contactless card test equipment is usually a dedicated radio frequency test machine, which uses modulated radio frequency to send commands to the chip to be tested and receive the returned information from the chip to be tested. The baseband signal, clock, and energy of the chip to be tested All are obtained thro...
