Beyond that, even at a base level it would still provide increased security by forcing the onlooker to memorize a longer string, thus in essence making a "long PIN" (i.e. 6, 8, 10 or more digits) the default while only having to memorize a shorter pin as a user.d) or by blocking the previous "correct" string after entry (for any given amount of time or amount of repeat entries), no? given amount of time or amount of repeat entries), no?
