Rubber stamps

Despite the technical innovations in the modern office, there is still a place for good old rubber stamps.
I know of two instances where this 'old school' technology is still being used. I work in a fairly 'advanced' office, but we still use a rubber date stamp to indicate when documents have been 'scanned'. In a much smaller business, I know of someone who has just bought a rubber stamp to mark invoices 'paid'. Another use that springs to mind, is a date stamp indicating when postal items were 'received'.

I am sure that the date stamp in particular will remain a useful item for the foreseeable future.
