The Arizona Cardinals were founded in 1898 as a club team by a Chicago builder named Chris O'Brien. They were known as the Morgan Athletic Club. The Chicago Cardinals were a charter member of the American Professional Football Association (renamed National Football League in 1922) in 1920. The Cardinals moved to St. Louis in 1960 and to Arizona in 1988.
* It should be noted that although they were founded in 1898, they experienced several periods of inactivity, including one that ended at the end of 1918. I could not find any historical records of the 1918 or 1919 seasons for the Cardinals. The Green Bay Packers were founded shortly after, in 1919, and although they didn't join the APFA (American Professional Football Association) until 1921, they were continuously playing football since 1919. The APFA was the forerunner to the NFL. Unless records of games are found for the Cardinals in 1918 or 1919, then the oldest continuously running NFL franchise would be the Packers.
However, if you want to get technical, the Green Bay Packers would actually be the oldest, as they can trace their lineage back to 1896 to semi-professional teams that played in Green Bay.
No, they are not. But they are the oldest franchise in the NFL's American Football Conference.

The franchise began as a group of friends who played football together on Chicago's South Side in 1898. Twenty-two years later, it became a charter member of the American Professional Football Association, later known as the NFL, after the group came up with the $100 franchise fee.

The NFL was established in 1920 as the American Professional Football Association consisting of 14 teams, one of them the Racine Cardinals, who were founded in 1901. After the 1920 season, they were re-named the Chicago Cardinals. The league changed its name to the National Football League in 1922. In 1960, the team moved to St. Louis, and in 1994 they again moved, this time to Arizona. Of today's existing NFL teams, the Arizona Cardinals are the oldest franchise.
