Exhibit 99.2

POSITIVEID CORPORATION

Unaudited Pro Forma Condensed Combined Financial Information

Basis of Pro Forma Presentation

On May 23, 2011, PositiveID Corporation, a Delaware corporation (the “Company”) acquired all of the outstanding capital stock of MicroFluidic Systems, a California corporation (“MicroFluidic”) (the “Acquisition”). Effective with the closing of the transaction, MicroFluidic became a wholly-owned subsidiary of the Company.

Under the purchase method of accounting the total estimated purchase price as described in Note 2 to this unaudited pro forma condensed combined financial information was allocated to the net tangible and intangible assets of MicroFluidic acquired in connection with the Acquisition based on their estimated fair values. The estimated fair values of certain assets and liabilities have been determined by management and are subject to change upon the finalization of the purchase accounting.

The historical consolidated financial information has been adjusted in the unaudited pro forma condensed combined financial information to give effect to pro forma events that are directly attributable to the acquisition, factually supportable, and, with respect to the statements of operations, expected to have a continuing impact on the combined results. The accompanying unaudited pro forma condensed combined statements of operations do not reflect a nonrecurring charge of approximately $525,000 expected to be recorded by the Company related to the direct costs of the Acquisition.

The unaudited pro forma condensed combined financial information does not purport to be indicative of the financial position or results of operations of the Company that would have been reported had the Acquisition been completed as of the dates or for such periods presented, nor is it intended to project the Company’s future financial position or results of operations. The unaudited pro forma condensed combined financial information and the accompanying notes should be read together with the Company’s audited consolidated financial statements and accompanying notes for the year ended December 31, 2010, Management’s Discussion and Analysis included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010, and the MicroFluidic audited financial statements and accompanying notes for the year ended December 31, 2010.

The unaudited pro forma condensed combined financial information as of and for the three months ended March 31, 2011 has been prepared from the Company’s unaudited condensed consolidated financial statements as of and for the three months ended March 31, 2011 and from the unaudited financial statements of MicroFluidic as of and for the three months ended March 31, 2011.

The unaudited pro forma condensed combined balance sheet as of March 31, 2011 has been prepared to present the Company’s financial position as if the Acquisition had occurred on March 31, 2011. The unaudited pro forma condensed combined statements of operations for the year ended December 31, 2010 and the three months ended March 31, 2011 have been prepared to present the Company’s results of operations as if the Acquisition had occurred on January 1, 2010 and January 1, 2011, respectively.

The pro forma adjustments are based on preliminary estimates, available information and certain assumptions, which may be revised as additional information becomes available. The unaudited pro forma condensed combined financial information does not reflect any adjustments for nonrecurring items or anticipated synergies resulting from the Acquisition.

1.   Acquisition of MicroFluidic

On May 23, 2011, the Company acquired all of the outstanding capital stock of MicroFluidic in a transaction accounted for using the purchase method of accounting. As consideration for the consummation of the Acquisition, the Company paid $250,000 to fund certain accounts payable of MicroFluidic (of which approximately $24,000 was paid to selling shareholders) and issued 2,375,000 shares of common stock of the Company (the “Stock Consideration”).  Additionally, the Company issued 850,000 shares of common stock to its advisor for services rendered in conjunction with the Acquisition. In connection with the Acquisition, the Company is also required to make certain earn-out payments, up to a maximum of $7,000,000, payable in shares of the Company’s common stock or in cash.

The estimated purchase price of the Acquisition totaled approximately $2,374,000, comprised of $24,000 in cash, the Stock Consideration valued at $950,000 (based upon a value of $0.40 per share), and contingent consideration of approximately $1,400,000. The fair value of the contingent consideration was estimated based upon the present value of the probability-weighted expected future payouts under the earn-out arrangement and is subject to change upon the finalization of the purchase accounting.

Under the purchase method of accounting, the estimated purchase price of the Acquisition was allocated to MicroFluidic’s net tangible and identifiable intangible assets and liabilities assumed based on their estimated fair values as of the date of the completion of the Acquisition, as described in the introduction to this unaudited pro forma condensed combined financial information, as follows (in thousands):
