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

misleading with respect to the period covered by this report;

4.  The  registrant's  other  certifying  officer  and  I  are  responsible  for
establishing and maintaining  disclosure  controls and procedures (as defined in

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) Intentionally omitted;

      c) Evaluated the effectiveness of the registrant's disclosure controls and

      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.
