Description of Business and Liquidity	NOTE 1 - DESCRIPTION OF BUSINESS AND LIQUIDITY I.D. Systems, Inc. and its subsidiaries (collectively, the “Company,” “we,” “our” or “us”) develop, market and sell wireless machine-to-machine solutions for managing and securing high-value enterprise assets. These assets include industrial vehicles such as forklifts and airport ground support equipment, rental vehicles and transportation assets, such as dry van trailers, refrigerated trailers, railcars and containers. The Company’s patented wireless asset management systems utilize radio frequency identification (RFID), Wi-Fi, Bluetooth, satellite or cellular communications, and sensor technology and software to address the needs of organizations to control, track, monitor and analyze their assets. Our cloud-based analytics software application for both industrial trucks and logistics assets is designed to provide a single, integrated view of asset activity across multiple locations, generating enterprise-wide benchmarks and peer-industry comparisons to provide an even deeper layer of insights into asset operations. Analytics determines key performance indicators relating to the performance of managed assets. The Company’s solutions enable customers to achieve tangible economic benefits by making timely, informed decisions that increase the safety, security, revenue, productivity and efficiency of their operations. The Company outsources its hardware manufacturing operations to contract manufacturers. I.D. Systems, Inc. was incorporated in Delaware in 1993 and commenced operations in January 1994. Liquidity On July 17, 2017, the Company closed an underwritten public offering consisting of 2,608,695 shares of common stock at a price per share of $5.75. In addition, the underwriters of the public offering exercised in full their option to purchase an additional 391,304 shares of common stock. Including this option exercise, the aggregate gross proceeds from the offering of a total of 2,999,999 shares of common stock, before deducting discounts and commissions and offering expenses, were approximately $17.3 million. Net proceeds from the public offering were approximately $16.1 million. The Company used a portion of the net proceeds from the offering to fund the Keytroller Acquisition (as defined below) and the remainder of the net proceeds for general corporate purposes. As of December 31, 2018, we had cash (including restricted cash), cash equivalents and marketable securities of $15.0 million and working capital of $15.8 million. The Company’s primary sources of cash are cash flows from operating activities and the Company’s holdings of cash, cash equivalents and investments from the sale of common stock. To date, the Company has not generated sufficient cash flows solely from operating activities to fund its operations. We believe our available working capital, anticipated level of future revenues and expected cash flows from operations will provide sufficient funds to cover capital requirements through at least March 31, 2020. Keytroller Acquisition On July 31, 2017, we, together with our wholly-owned subsidiary Keytroller, LLC, a Delaware limited liability company (“Keytroller”), acquired substantially all of the assets of Keytroller, LLC, a Florida limited liability company (the “Keytroller Acquisition”). The business we acquired in the Keytroller Acquisition develops and markets electronic products for managing forklifts and construction vehicles. The Keytroller Acquisition gives us a full suite of industrial fleet management product offerings capable of covering any sized fleet and budget and provides our industrial truck business more scale, both from a product and revenue standpoint and markets its line of forklift management devices mainly through a network of lift truck dealers, offering solutions for different fleet sizes at a wide range of price points.
