Item 1. Security and the Issuer.

The class of equity securities to which this statement relates is common stock, par value $ 0.0001 per share (the “Common Stock”), of BIO-key International, Inc., a Delaware corporation (the “Issuer”). The principal executive offices of the Issuer are located at 3349 Highway 133, Building A, Suite E, Wall, NJ 07719.

Item 2. Identity and Background

The Reporting Person filing this statement is Micron Technology Development Limited (the “Reporting Person”).

The place of organization of the Reporting Person is Hong Kong.     

The principal business of the Reporting Person is investment holding.     

The address of the principal office for the Reporting Person is Unit 1903, 19/F, Tower 2, Lippo Centre,

No. 89 Queensway, Hong Kong 999077

During the last five years, the Reporting Person has not been convicted in a criminal proceeding (excluding traffic violations and similar misdemeanors).

During the last five years, the Reporting Person has not been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding, was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws, or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration.

Pursuant to a securities purchase agreement between the Issuer and the Reporting Person, on November 11, 2015, the Reporting Person purchased 75,000 shares (the “Series B-1 Shares”) of Series B-1 Convertible Preferred Stock at a purchase price of $100.00 per share, for aggregate gross proceeds of $7,500,000. The purchase price for the Series B-1 Shares was paid from the working capital of the Reporting Person. The Series B-1 Shares are convertible at any time at the option of the Reporting Person into shares of Common Stock at an initial conversion price of $0.30 per share, subject to a “blocker provision” which prohibits conversion if such conversion would result in the holder being the beneficial owner of in excess of 9.99% of the Issuer’s outstanding shares of Common Stock. The securities purchase agreement contains a “standstill provision” which prohibits the Reporting Person either alone or together with any other person, from acquiring additional shares of the Issuer’s common stock or any of the Issuer’s assets, soliciting proxies, or seeking further representation on the Issuer’s board of directors.

On March 23, 2018, the Issuer received notice from the Reporting Person of its desire to increase its maximum percentage of beneficial owner from 9.99% to 19.99%. In connection with this request, the Issuer entered into a securities purchase agreement with the Reporting Person to purchase 82,755 shares of Common Stock in consideration of the conversion of an accrued dividend payable on the Series B-1 Shares in the amount of $297,917 resulting in a per share purchase price of $3.60. Effectiveness of the increase in the maximum beneficial ownership of the Reporting Person and conversion of dividends required the Issuer to waive the “standstill provision” included in the securities purchase agreement dated November 11, 2015 by and between the Issuer and the Reporting Person. The Issuer waived the “standstill provision” for the purpose of permitting the Reporting Person to convert additional shares of Series B-1 Shares into Common Stock so long as after giving effect to any such conversions, the Reporting Person does not beneficially own in excess of 19.99% of the Issuer’s Common Stock.

On March 23, 2018, the Issuer received a conversion notice from the Reporting Person to convert 31,140 Series B-1 Shares. Each share of the Series B-1 Shares has an original issue price of $100.00 and is convertible into shares of the Issuer’s common stock at a conversion price of $3.60 per share. The forgoing conversion resulted in the issuance of 865,000 shares of Common Stock.

Item 4. Purpose of Transaction.

The Series B-1 Shares were purchased for investment purposes. Pursuant to the Certificate of Designation of the Series B-1 Shares, the holders of a majority of the Series B-1 Shares have the right to nominate one person to serve on the Board of Directors of the Issuer. The Reporting Person holds over 98% of the issued and outstanding Series B-1 Shares. Except as set forth in the preceding sentence, the Reporting Person does not have any plans or proposals which relate to or would result in any of the events specified in (a) through (j) of Item 4 of Schedule 13D.

(a) The Reporting Person beneficially owns 2,166,089 shares of Common Stock, which consists of 947,755 shares of Common Stock and 1,218,334 shares of Common Stock issuable upon conversion of the Series B-1 Shares. The shares of Common Stock beneficially owned by the Reporting Person constitute 18.2% of the Issuer’s outstanding shares of Common Stock.

(b) The Reporting Person exercises sole voting and dispositive power with respect to the shares of Common Stock beneficially owned by the Reporting Person.  

(c) On March 23, 2018, the Issuer received notice from the Reporting Person of its desire to increase its maximum percentage of beneficial owner from 9.99% to 19.99%. In connection with this request, the Issuer entered into a securities purchase agreement with the Reporting Person to purchase 82,755 shares of Common Stock in consideration of the conversion of an accrued dividend payable on the Series B-1 Shares in the amount of $297,917 resulting in a per share purchase price of $3.60. Effectiveness of the increase in the maximum beneficial ownership of the Reporting Person and conversion of dividends required the Issuer to waive the “standstill provision” included in the securities stock purchase agreement dated November 11, 2015 by and between the Issuer and the Reporting Person. The Issuer waived the “standstill provision” for the purpose of permitting the Reporting Person to convert additional shares of Series B-1 Shares into Common Stock so long as after giving effect to any such conversions, the Reporting Person does not beneficially own in excess of 19.99% of the Issuer’s Common Stock.

On March 23, 2018, the Issuer received a conversion notice from the Reporting Person to convert 31,140 Series B-1 Shares. Each share of the Series B-1 Shares has an original issue price of $100.00 and is convertible into shares of the Issuer’s common stock at a conversion price of $3.60 per share. The forgoing conversion resulted in the issuance of 865,000 shares of Common Stock.
