An individual’s PIN is the four-digit code they set after opening a debit account with their bank of choice. It is used as a layer of authentication when they perform an electronic transaction ...
The problem with guessable PINs surprisingly worsens when customers are forced to use additional digits, moving from about a 25% probability with fifteen numbers to more than 30% (not counting 7-digits with all those phone numbers). In fact, about half of all 9-digit PINs can be reduced to two dozen possibilities, largely because more than 35% ...
The PIN block is constructed by XOR-ing two 64-bit fields: the plain text PIN field and the account number field, both of which comprise 16 four-bit nibbles. The plain text PIN field is: one nibble with the value of 0, which identifies this as a format 0 block; one nibble encoding the length N of the PIN; N nibbles, each encoding one PIN digit
1234 is the natural number following 1233, and preceding 1235.It has two distinct prime factors, 2 and 617, making it a squarefree semiprime. [1] It is the number of independent vertex sets in a 4×4 square grid, or equivalently, the number of distinct 4×4 binary matrices in which no two adjacent elements are both equal to 1.
If the wrong PIN is entered more than three times, the SIM card will become locked. It can be unlocked by entering the PUK code provided by the mobile service provider, [1] which may be available on the SIM card's packaging, the contract, or provided by customer service after identity verification.

Computer and Internet versions of the game have also been made, sometimes with variations in the number and type of pieces involved and often under different names to avoid trademark infringement. Mastermind can also be played with paper and pencil. There is a numeral variety of the Mastermind in which a 4-digit number is guessed. [24]
