Ladies and Gentlemen:

This opinion is furnished to you in connection with a registration statement on
Form S-8 (the "Registration Statement"), filed with the Securities and Exchange
Commission under the Securities Act of 1933, as amended, for the registration of
600,000 shares of Common Stock, $.01 par value (the "Shares"), of TransAct
Technologies Incorporated, a Delaware corporation (the "Company"). The Shares
are issuable under the Company's 2005 Equity Incentive Plan (the "Plan").

We are familiar with the actions taken by the Company in connection with the
adoption of this Plan. For purposes of our opinion, we have examined and relied
upon such documents, records, certificates and other instruments as we have
deemed necessary. The opinions expressed below are limited to the Delaware
General Corporation Law, including the applicable provisions of the Delaware
Constitution and the reported cases interpreting those laws.

Based on the foregoing, we are of the opinion that the Shares have been duly
authorized and, when the Shares have been issued and sold in accordance with the
terms of the Plan, the Shares will be validly issued, fully paid and
nonassessable.

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement. Our consent shall not be deemed an admission that we are
experts whose consent is required under Section 7 of the Securities Act of 1933.

It is understood that this opinion is to be used only in connection with the
offer and sale of Shares while the Registration Statement is in effect.

Very truly yours,

/s/ ROPES & GRAY LLP
