When it comes to marked decks, two technologies reign supreme: infrared marked cards and UV marked playing cards. Both have their advantages, drawbacks, and best applications. At MarkedCardsUSA, we stock both and want you to know which one is right for you. Below, we compare them, explain how they work, and assist you in making the right decision.

What Are Infrared Marked Cards?

Infrared marked cards are printed with invisible inks under regular lighting and are only visible when seen through infrared filters, infrared contact lenses, or infrared enabled scanners. To all unassisted observers, such decks appear and feel like regular playing cards.

Since the markings are beyond the visible spectrum, they provide excellent stealth. Infrared materials are invisible to regular surveillance cameras, UV lighting, or the naked eye in normal lighting.

Most industry experts regard infrared marking technology as today's "gold standard" of hidden reading.

There are two principal forms:

Infrared contact-lens or glass reading — most popular. You have lenses or glasses fitted with an IR filter to read the markings.

Infrared camera / scanner systems — less often used for everyday situations; usually employed in situations where an IR camera hidden from view reads marked cards remotely.

Advantages of infrared marked cards:

• Great concealment — markings are basically undetectable to non-equipped spectators
• Compatibility with IR filter lenses or glasses
• Long-term lifespan when executed well

If you play serious poker, host tournaments, or require the utmost level of secrecy, infrared marked cards are usually the preferred option.

What Are UV Marked Playing Cards?

UV ink marked playing cards (ultraviolet marked cards) employ inks that fluoresce or appear using ultraviolet light or UV-filter lenses/glasses. They are invisible under normal lighting conditions.

They are more available and inexpensive means to become familiar with marked decks, and for that reason, most hobbyists, casual players, and magicians use them.

Benefits are:

• Less expensive compared to infrared systems
• Simpler entry point for beginners
• Beneficial for magic performances, mentalism, or training routines
• Easily detectable with compatible UV glasses or lenses

However, there are compromises. UV marks may be less hidden in some lighting or situations, and under intense UV or examination they could be more noticeable.

Additionally, more affordable UV decks may fade or degrade more quickly.

However, for performance, training, or recreational play, uv marked playing cards hit a balance.

If maximum stealth and live play advantage are your aim, infrared marked cards are usually the better option. If you'd rather have a less expensive option that is easy to use and perfectly adequate for performances or practice, UV marked playing cards offer great value.

Infrared vs UV: Side-by-Side Comparison

Here’s a quick comparison to help you choose:

If your goal is maximum stealth and real-time gameplay advantage, infrared marked cards are often the superior choice. If you want something more affordable, easy to use, and well suited for performances or practice, UV marked playing cards give excellent value.

How to Employ Infrared & UV Marked Decks Efficiently

• Pair ink spectrum with lens filters

  Always make sure the spectral response of the marking ink perfectly matches your reading glasses or lenses. Incompatibility will render markings invisible or pale.

• Practice reading speed and ergonomics

  Discover how to look at the back, read fast without being suspicious, and conceal your lens movements.

• Take care of your deck

  Maintain clean cards, never bend or scrub them, and keep them in protective cases in order to maintain marking clarity.

• Test under varying light

  Test your deck in dim room lighting, with fluorescent, LED, or low light to ensure invisibility. Test also using your UV or IR equipment to ensure readability.

• Upgrade or blend decks

  You may keep both infrared and UV decks — utilizing IR for serious or confidential games and UV for shows or practice.
