Was quoted:

I'm afraid JKR has said that this can't be the case. Taking this
from JKR's webiste, rumour section:

"The Order of the Phoenix communicates using chocolate frog cards

"This is such a great idea that I was in two minds whether to shoot
it down; however, *a chocolate frog card, or any object that would
have to be remembered and carried on the person, would always be
vulnerable to loss, destruction or trickery*. The Order communicates
in a way that requires *nothing but a wand*. You saw the Order's
method of communication in use even before you knew about the
existence of the Order; it was employed by an Order member."

Bonnie:

Chapter 28 of GOF

speaking of DD  " He raised his wand into the air and pointed it in 
the direction of Hagrid's cabin.  Harry saw something silvery dart 
out of it and streak away through the trees like a ghostly bird."


Bonnie again:

Then shortly afterward Hagrid appears.  I wonder if this silvery 
stuff is the same stuff in the pensives.  -Thoughts- perhaps?
