Moonwalking With Einstein
A memory is a pattern of connections between your neurons.
Memory Palace or Method of Loci
Convert something unmemorable into a series of engrossing visual images and mentally arrange them within an imagined space, and suddenly those forgettable items become unforgettable.
Use vivid images that stand out for words and objects.
Major System
A simpler way to remember numbers. Wiki
PAO (person, action, object)
Faster but more difficult to master. This can be used for numbers and a deck of cards. Wiki
Every two-digit number from 00 to 99 is represented by a single image of a person performing an action on an object. Any six-digit number, like say 34-13-79, can then be turned into a single image by combining the person from the first number with the action from the second and the object from the third. Remember unique images. Like Michael jordan dunking over someone with a basketball and breaking the glass.
