Ladies and Gentlemen:

We have acted as special Georgia counsel for Fidelity National Information Services, Inc., a Georgia corporation (the “Company”), regarding the preparation and filing of this opinion letter with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), in connection with a registration statement on Form S-3 (the “Registration Statement”) relating to the following securities of the Company: (i) unsecured senior debt securities (the “Senior Debt Securities”); (ii) unsecured subordinated debt securities (together with the Senior Debt Securities, the “Debt Securities”); (iii) guarantees by the Guarantors of the Debt Securities (the “Guarantees”); (iv) shares of common stock, par value $0.0001 per share (the “Common Stock”); (v) shares of preferred stock, par value $0.0001 per share (the “Preferred Stock”); (vi) depositary shares (the “Depositary Shares”) in the form of fractional interests in Debt Securities or fractional shares of the Preferred Stock in each case evidenced by depositary receipts (the “Receipts”); (vii) warrants to purchase Common Stock, Preferred Stock, Debt Securities or other securities described in the Registration Statement, or any combination of them (collectively, the “Warrants”); (viii) contracts for the purchase and sale of Common Stock, Preferred Stock, Debt Securities or other securities described in the Registration Statement (the “Purchase Contracts”); and (ix) units of the Company, consisting of one or more of the other securities described in the Registration Statement or debt obligations of third parties, including U.S. Treasury Securities (the “Units,” and together with the Debt Securities, the Guarantees, the Common Stock, the Preferred Stock, the Depositary Shares, the Receipts, the Warrants and the Purchase Contracts, the “Offered Securities”). The Offered Securities will be issued from time to time pursuant to the provisions of Rule 415 under the Securities Act.

As such special Georgia counsel, and as a basis for the opinions hereinafter set forth, we have examined and are familiar with (i) the articles of incorporation and bylaws of the Company (each as amended to date), (ii) the Registration Statement and (iii) resolutions of the directors of the Company. In addition, we have made such investigations of law and have examined such certificates of public officials and officers of the Company and such other documents and records as we have deemed necessary for purposes of this opinion letter.
