Abstract

A combination magnetic-stripe card reader with integrated contact-less chip card read/write functions, a direct replacement for a standard player tracking magnetic-stripe card reader installed in slot machines. It is a form, fit and function for existing player tracking readers, having the same front panel appearance, the same physical envelope, using the same mounting method, using the same cable connections and operating in the identical manner. The combined functions requires two command sets and a method to distinguish between them, the legacy command set of the existing reader to be replaced which is typically strings of American Standard Code for Information Interchange (ASCII) eight bit characters with a line terminator character and the contact-less chip card requiring the ability to send and receive all possible eight bit values with varying length commands and not having a dedicated character value to indicate the end of a command.

Dependent claims

A replacement reader device capable of interfacing with a card for use in a gaming machine, the gaming machine including a gaming cabinet having a cutout, a gaming machine controller, a mounting, and a magnetic stripe card reader, the controller and magnetic stripe card reader contained in the gaming cabinet and the magnetic stripe card reader mounted on the mounting with access through the cutout, the replacement reader device for replacement of the magnetic stripe card reader mounted in the gaming cabinet, the replacement reader device comprising:

a reader body having approximately the same dimensions as the magnetic strip card reader, the reader body mountable on the mounting within the gaming cabinet;
magnetic stripe reader electronics comprising:
an input/output interface in communication with the gaming machine controller when the replacement reader device is mounted in the gaming machine;
a magnetic stripe read head configured to recover raw data from a magnetic stripe on the card;
an amplifier, peak detector and comparator in communication with the magnetic stripe read head configured to convert the raw data from the magnetic stripe read head to logic levels;
a first micro-controller in communication with the input/output interface and the amplifier, peak detector and comparator configured decode logic levels received from the amplifier, peak detector and comparator, and to process a first set of commands;
card sensing means in communication with the first micro-controller configured to signal the first micro-controller when the card is detected;
and
contactless chip card reader electronics in communication with mating electronics comprising:
an RF receiver/transmitter in communication with a loop-coupling antenna;
and
a second micro-controller configured to process a second set of commands and to communicate with the RF receiver/transmitter,
wherein the magnetic stripe reader electronics are attached to a first board at the top or the bottom of the reader body and the contactless chip card reader electronics are attached to a second board at the bottom or top of the reader body opposite the first board;
and
a common entry slot, wherein the device is operable to read a magnetic stripe card inserted in the common entry slot, and operable to attempt to read for a magnetic strip card inserted in the common entry slot via the magnetic strip read head and to activate the RF receiver/transmitter to read a contactless chip card only when the contactless chip card is inserted into the common entry slot and after the device attempts to read for a magnetic stripe card.
