Combination magnetic stripe and contact-less chip card reader

A reading and writing device capable of interfacing with a card for use in a wagering type gaming machine comprising:

• a housing fitting within the same physical envelope in the wagering type gaming machine holding an existing magnetic card reader operable to solely read magnetic stripe cards:
• a bezel attached to the housing, the bezel protruding from a rectangular cutout of a front panel of the gaming machine;
• magnetic stripe reader electronics comprising:
• an input/output interface in communication with a gaming machine controller;
• 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;
• and
• card sensing means configured to output a signal when the card is detected;
• contactless chip card reader/writer electronics comprising:
• an RF receiver/transmitter in communication with a loop-coupling antenna;
• and
• a micro-controller in communication with:
• the input/output interface, with the magnetic stripe reader electronics, the contactless chip card reader/writer electronics and configured to decode logic levels received from the amplifier, peak detector and comparator;
• the micro-controller processes the commands to operate both the magnetic stripe reader electronics and the contactless chip card reader electronics and interface with the gaming machine controller through upgraded software executed by a controller of the gaming machine, and
• a common entry slot in the bezel, wherein the reading and writing device is operable to read only part of a magnetic stripe of a magnetic stripe card during the card being inserted in the slot, the card solely transported in the common entry slot by a user inserting the card, and wherein the card is held in a stationary position in the common entry slot after insertion, wherein the magnetic stripe of the card is partially inserted in the slot when the card is held in the stationary position;
• and operable to activate the RF receiver/transmitter to read a contactless chip card only when the contactless chip card is partially inserted into the common entry slot and held in a stationary position, wherein the contactless chip card is solely transported in the slot via a user inserting the contactless chip card.

A method to retrofit a gaming machine having a partial insertion magnetic card reader reading only magnetic cards to read both magnetic stripe cards and contactless chip cards, the method comprising:

• removing the magnetic card reader from a rectangular cutout on a front panel of the gaming machine;
• inserting a reading and writing device in the rectangular cutout on the front panel the gaming machine, the reading and writing device comprising:
• magnetic stripe reader electronics including:
• an input/output interface in communication with a gaming machine controller;
• 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 to decode logic levels received from the amplifier, peak detector and comparator, and to process a first set of commands to direct reading a magnetic stripe card;
• card sensing means in communication with the first micro-controller configured to signal the first micro-controller when the card is detected;
• contactless chip card reader/writer electronics in communication with mating electronics including:
• an RF receiver/transmitter in communication with a loop-coupling antenna;
• and
• a second micro-controller configured to process a second set of commands to direct reading a contactless chip card, and to communicate with the RF receiver/transmitter;
• and
• a common entry slot, wherein the reading and writing device is operable to read only part of a magnetic stripe of a magnetic stripe card during the card being inserted in the slot, the card solely transported in the common entry slot by a user inserting the card, and wherein the card is held in a stationary position in the common entry slot after insertion, wherein the magnetic stripe of the card is partially inserted in the slot when the card is held in the stationary position and operable to activate the RF receiver/transmitter to read a contactless chip card only when the contactless chip card is partially inserted into the common entry slot and held in a stationary position, wherein the contactless chip card is solely transported in the slot via a user inserting the contactless chip card;
• connecting the input/output interface with the gaming machine controller;
• and
• upgrading software of the gaming machine controller to communicate with the reading and writing device.
