ColDiFra helps philatelists in Italian Republic stamps (just stamps) collecting, by the Missing and Double list.
All the Italian Republic stamps are present and visualised in the catalog.
Periodic releases adding the latest stamp emissions.
For each stamp the basic information are shown (emission year, Unificato/Sassone code, description and value).
It is possible to have more detailed information (emission day and month, long and exhaustive description, both Unificato and Sassone code).
An easy link to that stamp iBolli page is available.
Long clicking each stamp changes it into missing or not and double or not.
Also, using Missing and Double list ColDiFra defines and checks the exchange with other philatelists:-
. it is possible to automatically send missing/double list by e-mail (even if each philatelist uses different codes)
. the number and the value of possible exchange are visualised
. the stamp values are updated according to iBolli values
. we may use it even if our double stamp situation has not been updated.
Item colors easy identify if we have that stamp (normal color), if it is missing (red) or double (blue).
It is possible to save the missing and double stamps situation generating an e-mail (to ourselves).
Downloading that e-mail content, we may restore that e-mail situation.
We may have more information by the User guide, accessible from home.
Available in English and Italian (easy to set and change).
