              APPLIED DIGITAL SOLUTIONS, INC. AND SUBSIDIARIES

   CERTIFICATION PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002


I, Evan C. McKeown, certify that:


1. I have reviewed this Amendment No. 1 to the Annual Report on Form 10-K/A
of Applied Digital Solutions, Inc.;

2. Based on my knowledge, this 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 report;

3. Based on my knowledge, the financial statements, and other financial
information included in this 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 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 or caused such
       disclosure controls and procedures to be designed under our
       supervision 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 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 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 annual report) that has materially
       affected, or is reasonably likely to materially affect, the
       registrant's internal control over financial reporting.

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

       a) All significant deficiencies and material weaknesses in the design
       or operation of internal control over financial reporting which are
       reasonably likely to adversely affect the registrant's ability to
       record, process, summarize and report financial information; and

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