What 🂠 means
Patterns helped conceal identifying marks and wear.
For the first several centuries of card use in Europe, backs were often plain or simply coloured. Patterns made identifying marks and wear harder to spot, then became part of a deck's visual identity. The glyph is schematic and font-dependent; it does not reproduce any real deck.
If you're asking whether this is a tarot symbol, context matters: the glyph supplies only a generic card back. Tarot began as a card game; its earliest references date to the 1440s and 1450s, while its occult and fortune-telling association gained currency in the 19th century.
