1.   I
have reviewed this quarterly report on Form 10-Q of PRINCETON SECURITY
TECHNOLOGIES, INC.;





2.  Based
on my knowledge, this quarterly report does not contain any untrue statement of
a material fact or omit to state a material fact necessary to make the
statements made, in light of the circumstances under which such statements were
made, not misleading with respect to the period covered by this quarterly
report;





3.   Based
on my knowledge, the financial statements, and other financial information
included in this quarterly report, fairly present in all material respects the
financial condition, results of operations and cash flows of the registrant as
of, and for, the periods presented in this quarterly report;





4.   The
registrant's other certifying officer and I are responsible for establishing and
maintaining disclosure controls and procedures (as defined in Exchange Act Rules
13a-15(e) and 15d-15(e)) and internal control over financial reporting (as
defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and
have;





(a)  Designed
such disclosure controls and procedures to ensure that material information
relating to the registrant, including its consolidated subsidiaries, is made
known to us by others within those entities, particularly during the period in
which this quarterly report is being prepared;





(b)  Designed such internal
control over financial reporting, or caused such internal control over financial
reporting to be designed under our supervision, to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of
financial statements for external purposes in accordance with generally accepted
accounting principles;





(c)  Evaluated
the effectiveness of the registrant's disclosure controls and procedures as of a
date within 90 days prior to the filing date of this quarterly report (the
"Evaluation Date") and presented in this report our conclusions about the
effectiveness of the disclosure controls and procedures, as of the end of the
period covered by this report based on such evaluation; and





(d)  Disclosed
in this report any change in the registrant’s internal control over financial
reporting that occurred during the registrant’s most recent fiscal quarter (the
registrant’s fourth fiscal quarter in the case of an quarterly report) that has
materially affected, or is reasonably likely to materially affect, the
registrant’s internal control over financial reporting; and





5.   The
registrant's other certifying officer and I have disclosed, based on our most
recent evaluation, to the registrant's auditors and the audit committee of
registrant's board of directors (or persons performing the equivalent
functions):





(a)  All
significant deficiencies in the design or operation of internal controls which
could adversely affect the registrant's ability to record, process, summarize
and report financial data and have identified for the registrant's auditors, any
material weaknesses in internal controls; and





(b)  Any
fraud, whether or not material, that involves management or other employees who
have a significant role in the registrant's internal controls.
