           I.D. SYSTEMS, INC. REPORTS SECOND QUARTER FINANCIAL RESULTS

Hackensack, NJ, August 4, 2004 --

I.D. Systems, Inc. (NASDAQ:  IDSY) today announced its financial results for the
second  quarter  ended  June 30,  2004.  Revenues  increased  77% to  $3,764,000
compared to revenues of $2,125,000 for the three months ended June 30, 2003. Net
income for the  quarter  increased  to  $242,000,  or $.03 per basic and diluted
share,  compared  to a net loss of  $211,000,  or ($.03)  per basic and  diluted
share,  for the same period last year.  The  increase in revenues and net income
was primarily  attributable to continued  customer  acceptance and demand of the
company's  patented  Wireless  Asset  Net(TM)  system for  tracking and managing
fleets of industrial equipment.

For the  six-month  period  ended  June  30,  2004,  revenues  increased  73% to
$6,469,000  compared to $3,734,000  for the same period in 2003.  Net income for
the six months ended June 30, 2004 increased to $337,000  compared to a net loss
of $596,000 for the same period last year.

"We are very  pleased to report  another  significant  increase in revenues  and
another  profitable  quarter at I.D. Systems," said Jeffrey Jagid, the company's
chairman and chief executive  officer.  "We continue to expand sales of our core
wireless  vehicle  management  technology into key markets,  including  material
handling  operations  at the plants  and  distribution  centers  of Fortune  500
corporations,  and the emerging homeland security infrastructure at airports and
seaports.  I.D. Systems is also making significant  progress in the rental fleet
market,  where a  version  of our  Wireless  Asset Net  system is  demonstrating
important  benefits in a pilot  program with Avis Rent A Car. We look forward to
building on our success and leadership in these  markets,  as well as developing
new  application  solutions,  to continue  driving  product demand and income to
higher levels."

"We are gratified that our customers are utilizing I.D.  Systems'  technology in
an  effort  to  improve  security,  safety,  productivity,   cost  savings,  and
profitability,"  added Mr.  Jagid,  "and I am  pleased  to note that some of our
customers'   experiences   are   portrayed   on  our  newly   revised   website,
www.id-systems.com."

"I.D.  Systems continues to adhere  successfully to its strategic business plan,
balancing  rapid growth with cost  containment and winning key contracts to fund
our research and development  investments," said Ned Mavrommatis,  I.D. Systems'
chief  financial  officer.  "In the second  quarter of 2004,  we again  achieved
sequential as well as year-over-year growth of both revenues and net income, and
we maintained  gross profit  margins at 50%.  Overall,  the company's  financial
condition  remains strong.  As of June 30, 2004, I.D. Systems had  approximately
$9.5 million in cash, cash equivalents and investments,  and approximately $10.4
million  of  working  capital,   compared  to  approximately  $8.6  million  and
approximately $8.2 million, respectively, at December 31, 2003."

Selling,  general and administrative  (SG&A) expenses for the quarter ended June
30, 2004 were $1,434,000  compared to $1,105,000 for the three months ended June
30, 2003 as sales,  marketing and customer service payroll expenses increased to
support  growing  sales.  As a percentage  of revenues,  however,  SG&A expenses
decreased to 38% for the quarter compared to 52% for the three months ended June
30, 2003.

Research and development  (R&D)  expenditures for the quarter were $283,000,  up
from $219,000 in the second quarter a year ago. As a percentage of revenues, R&D
expenses  decreased  to 7.5% for the  quarter  compared  to 10.3%  for the three
months ended June 30, 2003.

                                                                     Page 1 of 4
