A portable anti-theft IC card reading and writing device and reading and writing method

Abstract

The invention provides a portable antitheft IC card reading and writing device and a reading and writing method. The reading and writing device comprises a microprocessor, a USB interface, a power supply, a power supply mode switching circuit, a total current sampling circuit, reading and writing card equipment, display touch equipment, a communication module, a background server and a card issuing mechanism server. In different states of the IC card reading and writing device, a current is detected and monitored. According to an experience, a preset threshold is set. If a detected current calculation value is higher than the preset threshold, corresponding alarm information is output. The portable antitheft IC card reading and writing device and the reading and writing method possess advantages that whether the IC card reading and writing device is snugly embedded into a stealing device can be simply, rapidly and sensitively detected; the structure is simple and is easy to expand; and usage safety of the portable IC card reading and writing device is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of intelligent IC card reading and writing equipment, and in particular relates to a portable anti-theft IC card reading and writing device and a reading and writing method.

Problems solved by technology

For example, for a bus card with no balance, the user needs to queue up at a designated place to recharge, during which the user may miss the subway to the company early in the morning; for an ETC card that is about to be overdrawn, the user needs to go to the designated service point to recharge, and If you bind a bank card, you are worried about insecurity; not to mention the electronic cash of the bank card, its loading experience and usage scenario problems directly lead to the failure of offline QuickPass
