Each time you shop using credit card, then there is a process of validity of a credit card known as Authentication, which is a process of checking whether the credit card you use is still valid or not.

There are 16 DIGIT on Credit Card Number Such.
Step I,
Multiply ALL DIGIT NUMBERS the ODD with "2", then:
- If the results More than 9 then REDUCE THE RESULT with "9",
- If the result is less than 9, leave it alone.
After the Sum of EVERYTHING.
Digit 1: 5; 5x2 = 10 {More than 9}, so 10-9 = 1
Digit 3: 7; 7x2 = 14 {More than 9}, so 14-9 = 5
Digit 5: 5; 5x2 = 10 {More than 9}, so 10-9 = 1
Digit 7: 3; 3x2 = 6 {Let it go, because LESS THAN 9}
Digit 9: 1; 1x2 = 2 {Let it go, because LESS THAN 9}
Digit 11: 1; 1x2 = 2 {Let it go, because LESS THAN 9}
Digit 13: 8; 8x2 = 16 {More than 9}, so 16-9 = 7}
Digit 15: 2; 2x2 = 4 {Let it go, because LESS THAN 9}
Then add:
5 + 1 + 1 + 6 + 2 + 2 + 7 + 4 = 28
Step II,
Sum the Digits in positions No. Even on the data Credit cards 5378-5432-1011-8224
Digit 2: 3
Digit 4: 8
Digit 6: 4
Digit 8: 2
Digit 10: 0
Digit 12: 1
Digit 14: 2
Digit 16: 4
--------------- +
Amount: 24
Step III,
Add up the results of the first step with the Step II
28 + 24 = 52
Because 52 is not divisible by "10" (still leaving numbers
ie 5,2 decimal), then the CREDIT CARD IS NOT VALID / INVALID / CAN NOT BE USED.
Easy, is not it?
