Ladies and Gentlemen:

We have acted as Georgia counsel to Fidelity National Information Services, Inc., a Georgia corporation (the “Company”), in connection with the issuance and sale by the Company of €500,000,000 aggregate principal amount of floating rate senior notes due 2028 (the “Floating Rate Notes”), and €500,000,000 aggregate principal amount of 3.450% senior notes due 2030 (the “Fixed Rate Notes” and, together with the Floating Rate Notes, the “Securities”) to be offered pursuant to the Underwriting Agreement, dated as of March 5, 2026, by and among the several underwriters named therein and the Company (the “Underwriting Agreement”). The Securities are being issued pursuant to the Indenture, dated as of the date hereof (the “Base Indenture”), by and among the Company, the guarantors party thereto and U.S. Bank Trust Company, National Association, as trustee, as amended and supplemented by the first supplemental indenture, dated as of the date hereof, relating to the Floating Rate Notes (the “First Supplemental Indenture”), and the second supplemental indenture, dated as of the date hereof, relating to the Fixed Rate Notes (the “Second Supplemental Indenture” and together with the First Supplemental Indenture, the “Supplemental Indentures” and, together with the Base Indenture, the “Indenture”).

The offer and sale of the Securities is being made pursuant to the registration statement on Form S-3 (File No. 333-288198) filed by the Company with the Securities and Exchange Commission (the “Commission”) on June 20, 2025, as amended by Post-Effective Amendment No. 1 filed with the Commission on February 26, 2026 (as amended, the “Registration Statement”), which includes the Company’s base prospectus, dated June 20, 2025 (the “Base Prospectus”), the preliminary prospectus supplement, dated February 26, 2026, filed by the Company pursuant to Rule 424(b) under the Securities Act with respect to the Securities (the “Preliminary Prospectus Supplement” and, together with the Base Prospectus, the “Preliminary Prospectus”), and the final prospectus supplement, dated March 5, 2026 (the “Final Prospectus Supplement” and, together with the Base Prospectus, the “Prospectus”).

This opinion is being furnished to you at your request in accordance with the requirements of Item 601(b)(5) of Regulation S-K.
