In late 2007, CRR was hired to assist a client interested in a multi-card technology, which may also be referred to as electronic wallet technology.  Generally, the client was interested in a single card that could be carried in a wallet or purse, which could emulate all the various cards a person might typically carry with them including credit cards, debit cards, loyalty cards, and the like. 

In order to read the various cards and emulate them, the multi-card was required to read and write both bar codes and magnetic stripes, have a memory to store card data, and have a display having a graphical user interface for interacting with the card and for displaying card information (e.g., vendor name, logo, and barcode, etc.). 

In support of the client, CRR performed extensive prior art and technology analysis to determine a system and method for meeting the client’s multi-card technology requirements and assisted the clients and patent counsel in the preparation and filing of a provisional patent application on February 23, 2008 and a corresponding non-provisional patent application on February 23, 2009.  

In February 2013, CRR acquired rights to the multi-card technology from the client.  CRR successfully prosecuted the patent application resulting in issued U.S. patents 8,141,780; 8,622,300; 8,944,328; 9,154,602; 9,311,419; and 9,679,233; and a currently allowed patent application.  The patents cover a light transceiver and various devices having bar code reading capabilities including a phone and a watch and an electronic device that uses RF transmissions to communicate with a vendor point-of-sale device.
