Anti-recording card accepting device applied to automatic teller machine (ATM)

Abstract

The present invention discloses an anti-recording card treating mechanism which amounts to a recording medium insertion part of an automatic teller machine (ATM) and by which an operator inserts and pulls out a card. The device comprises an insertion slot which is a left-right extending slit-type opening, is formed in an external surface of the ATM and is used for insertion of the card; an upper concave part which is arranged inside the insertion slot and corresponds above a chip position of the card; a lower concave part which is arranged inside the insertion slot and corresponds below a magnetic stripe position of the card; front side conveying rollers and inner side conveying rollers, which are arranged in parallel with the insertion slot at the inner side of the ATM and used for conveying the card into and out of the inner side of the ATM; a plurality of laser thickness sensors installed in an embedded manner inside an upper projecting part of the insertion slot and used for detecting thickness of an inserted medium; and detection sensors with the number being the same as that of the laser thickness sensors. The anti-recording card accepting device is simple in structure and can effectively and reliably prevent recording, criminal acts of installation of a thin-type recording device are eradicated, and recording prevention of a chip card and a magnetic stripe card is achieved at the same time.

Description

technical field [0001] The invention relates to the field of automatic cash transaction devices, in particular to an anti-skimming card acceptance device used in ATMs. Background technique [0002] Automatic cash teller machine (Automated Teller Machine, hereinafter referred to as "ATM") and cash dispenser (Cash Dispenser, hereinafter referred to as "CD") accept cash cards or credit cards, etc., which have information recorded on the surface (customer information, etc.) Recording media in areas such as chips and magnetic stripes are subject to prescribed processing. In a recording medium accepting device such as an ATM or a CD, a crime called skimming in which information recorded on a recording medium is obtained illegally occurs both domestically and abroad. Skimming, for example, installs a skimming device on an insertion port for inserting a recording medium of an ATM or a CD, and reads the information recorded in the information recording area of ​​the recording medium...

AI Technical Summary

Problems solved by technology

However, the method of preventing skimming by generating a disturbing magnetic field has the problem of not being able to reliably prevent skimming when the device for eliminating the disturbing magnetic field is also used as a skimming device in addition to complicating and increasing the size of the device.

In addition, the method of using a sensor to prevent skimming has the problem of complicating and increasing the size of the device, and cannot prevent skimming by a skimming device that cannot be detected by a sensor, such as a thin skimming device.
