Face-down cards have no properties (name, Attribute, Type, Level/Rank, ATK, DEF, effect) until they are changed to face-up. A face-down card being looked at or revealed is still considered face-down (although its properties can be determined by card effects while being revealed) and is returned to its original position once the player(s) have finished viewing it.
In Yu-Gi-Oh! ARC-V, small orbs with glowing red eyes appear on top of face-down monsters.
In the Decks
Face-down cards in the Extra Deck can be looked at by their possessor at any time, but cannot be looked at by their opponent.

During a game, cards are normally placed face-down by Setting them. Face-down cards on the field can be looked at by their controllor at any time, but cannot be looked at by their opponent, unless stated otherwise.
Face-down cards on the field can be flipped face-up. (Flip Summon for monster and Activation for Spell/Trap cards, in general cases) Hwever, face-up cards cannot be Flipped face-down, unless an effect specifically states so.
Monster Cards can be placed on the field in face-down Defense Position (generally by Normal Set) (it is not possible for monsters to be in face-down Attack Position). Some effect may Special Summon face-down.
Link Monster cannot be placed face-down.
Spell and Trap Cards can be Set in the Spell & Trap Zones or the Field Zone (in the case of Field Spell Cards). Quick-Play Spell Cards and Trap Cards cannot be activated during the turn they are Set. It is not possible to Set Pendulum Monsters in Pendulum Zones.
Info on cards affected by Flipping face-down
When a card stops being face-up, in this case, because of being flipped face-down, it will lose some specific information/applications on it.
- Whether if it was placed on the field by specific method or not (Special Summoned by certain effect, Tributing a certain monster for Tribute Summon, etc).
- Any previously applied effects.
- Its place before being summoned/placed on the field.
Info not lost
- Material used for its summon.
- Its time of summon.
Some card effects can banish cards face-down. Cards that are banished face-down can be looked at by their possessor at any time, but cannot be looked at by their opponent. However, the number of banished cards (including face-down banished cards) is public knowledge.
