Portkey

A Portkey is an object enchanted to bring anyone who touches it to a specific location. Most of the time, a Portkey is an everyday object that would not draw the attention of a Muggle. Travelling by Portkey is said to feel like having a hook "somewhere behind the navel" pulling the traveller to their location.

Portkeys have an advantage over Floo powder in that they may transport many people at once, but each Portkey can only transport its users to one destination. Unlike Apparation, Portkeys may also be used by anyone, possibly even Muggles, though there are no known instances of this occurring. Portkeys travel to the destination along with their users; touching the Portkey again transports the users back to their original location. They are typically triggered by saying the numbers "One, Two, Three!"

Examples of Portkeys used in the books are the boot used to transport Harry Potter and the Weasley family to the Quidditch World Cup, and the Triwizard Cup, which was enchanted as a Portkey in order to transport Harry to Lord Voldemort. Also in the Battle of the Department of Mysteries, Albus Dumbledore used the incantation Portus to turn a statue into a Portkey, giving Harry Potter a chance to go back to Hogwarts.
