You can easily create you own PIN cards: as you can see, first you fill 4 PIN codes then a complete PIN card .
The PIN card consists of a rectangle of 40 colored squares in 5 rows of 8 squares.
The 40 squares are randomly distributed with red, green, blue and yellow squares.
Select four squares that you can remember.
On the right you can see ways to select a color pattern.
Enter your 4 pin code digits in the selected squares.
The PIN Key will fill the remaining 36 digits randomly with digits.
The PIN card then contains 40 digits with 4 of the same digit from 0 to 9.
Save you PIN card and you have it on your smart phone's display.
