                                                                 ------------

              APPLIED DIGITAL SOLUTIONS, INC. AND SUBSIDIARIES

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

I, Scott R. Silverman, certify that:

1. I have reviewed this annual report on Form 10-K/A Amendment No. 4
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; and

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 the registrant's board
of directors (or persons performing the equivalent functions):

         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.
