Upper Deck issued Ronaldo cards the following season with Manchester United, but the 2002-03 Panini issues from his Sporting CP days are the ones treated as his true rookie cards.

• Card number and set on the back must match the listing above; "rookie card" is a specific card, not any early card of the player.
• Print quality: genuine cards have crisp text and a regular dot pattern under magnification; reprints and fakes blur, especially in small type.
• Stock and size: compare thickness, gloss and corners against a common card from the same set.
• Chrome and Prizm parallels carry a foil, color or serial-number mark that the base card lacks; the base card is the reference rookie unless the source says otherwise.
• Grading is a separate step; a slab authenticates and grades, and the grading guide explains what the number means.

Shoot the front flat, straight on, in daylight, with all four corners in frame, then the back so the card number and copyright line are readable. For chrome or foil cards, take a second front shot tilted under the light to show the finish. The app reads the player, set and number; the checks above confirm the version.
