Abstract

The invention discloses a card reader compatible to contact and noncontact IC (integrated circuit) cards. The card reader comprises a master control chip, a safety module, a voltage stabilizing power supply chip, a USB (universal serial bus) interface, an analog front end chip and a noncontact intelligent IC read-write chip. A contact card seat is connected with a master control chip through the analog front end chip; a buzzer and three indicator lights are connected with the master control chip through I / O interfaces; three PSAM card seats are extended from the safety module, an LCD (liquid crystal display) screen and a code keyboard are externally connected with the master control chip through a PS / 2 interface, and the noncontact intelligent IC read-write chip is connected with the master control chip through a serial peripheral interface; the USB interface supplies power to the master control chip through the voltage stabilizing power supply chip. The card reader in USB communication is a drive-free plug-and-play card reader and quick and convenient to use and can be externally connected with the liquid crystal display screen and the code keyboard to achieve convenience in use.

Description

technical field [0001] The invention relates to the field of reader-writers, in particular to a card reader compatible with contact and non-contact IC cards. Background technique [0002] Magnetic stripe cards on the market are cheap to manufacture, low in safety performance, and easy to degauss. Criminals usually watch the cardholder enter the password through the monitoring camera installed on the ATM, steal the cardholder's password, and use it to steal the cardholder's credit card information. However, bank card copying equipment and even password stealing equipment have entered the market in large numbers. Equipment such as card readers can be easily bought online or in electronic markets, and the price of a complete set of equipment is not expensive. Bank magnetic stripe card fraud cases occur frequently, and various departments of the country also attach great importance to it. The central bank has new regulations, requiring economically developed regions to eliminat...
