We have acted as counsel for TransAct Technologies Incorporated, a Delaware corporation (the “Company”), in connection with the issuance and sale of 109,875 shares of the Company’s common stock, par value $.01 per share (the “Securities”), in a registered public offering.

In connection therewith, we have examined (i) the Registration Statement on Form S-3 (File No. 333-248055) (the “Initial Registration Statement”) filed by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”) on August 17, 2020, (ii) the Registration Statement on Form S-3 (File No. 333-258738) filed by the Company with the Commission on August 11, 2021 pursuant to Rule 462(b) promulgated under the Securities Act (together with the Initial Registration Statement, the “Registration Statements”), (iii) the prospectus of the Company, dated August 21, 2020, which forms a part of the Registration Statements, as supplemented by the prospectus supplement, dated August 12, 2021 (the “Prospectus Supplement”), relating to the offer and sale of the Securities, as filed with the Commission pursuant to Rule 424(b) under the Securities Act (as so supplemented, the “Prospectus”) and (iv) the Underwriting Agreement, dated August 12, 2021 (the “Underwriting Agreement”), between the Company and Roth Capital Partners, LLC, as representative of the several underwriters listed in Schedule I thereto. In addition, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the Certificate of Incorporation of the Company, as amended, and the Amended and Restated By-laws of the Company, each as currently in effect, relevant resolutions of the Board of Directors of the Company or committees thereof and such corporate records, documents, agreements, instruments and certificates of public officials of the State of Delaware and of officers of the Company as we have deemed necessary or appropriate in order to express the opinions hereinafter set forth.

In such examination, we have assumed, without inquiry, the legal capacity of all natural persons, the genuineness of all signatures on all documents examined by us, the authenticity of all documents submitted to us as originals, the conformity to the original documents of all such documents submitted to us as copies and the authenticity of the originals of such latter documents. We have also assumed that the books and records of the Company are maintained in accordance with proper corporate procedures. As to any facts material to our opinion, we have, when relevant facts were not independently established, relied upon the aforementioned records, documents, agreements, instruments and certificates and upon statements and certificates of officers and representatives of the Company and public officials.
