Title:
METHOD AND APPARATUS FOR INCREASING READ/WRITE SPEED OF CONTACTLESS CARD, AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/155734
Kind Code:
A1
Abstract:
A method and apparatus for increasing the read/write speed of a contactless card, a terminal device, and a computer readable storage medium, which are applicable to the technical field of communications, the method comprising: running a drive program of a POS terminal (S11); acquiring a communication signal between the drive program and an interface chip (S12), the interface chip acquiring, according to the communication signal, data that must be read/written by a contactless card, and a reader in which the interface chip is located exchanging data with the contactless card; acquiring a time sequence oscillogram of the drive program according to the communication signal (S13); acquiring the running time of the drive program according to the time sequence oscillogram (S14); and modifying the drive program according to the running time and a preset drive program modification rule so as to shorten the running time of the drive program (S15). By means of the described method, the speed of reading/writing a contactless card by means of the drive of a POS terminal may be increased such that the transaction speed of the contactless card may comply with authentication requirements during transaction speed authentication of the contactless card in a non real-time operating system platform.
