asp.net - Parse Credit Card input from Magnetic Stripe -

-

Does any magnetic card know how to parse the credit card string input from swipe?

I never tried to work on javascript parser. The input looks like this.

% BNNNNNNNNNNNNNNN ^ ^ DOE / JOHN ^ 1210201901000101000100061000000 ?; Nnnnnnnnnnnnnnnnn = 12102019010106111001?

There are N credit card numbers.

see:

  • Format code = "
  • B "- One letter (alpha only)
  • Primary account number (PAN) - up to 19 characters
  • Field Separator - One Letter (usually '^')
  • Name - Normally on the name of two to 26 characters, but does not always match the credit card number.
  • Field separator - One letter (usually '^')
  • Expiration date - four characters in the form of YYMM.
  • Service code - Three letters
  • Discretionary data - Pin verification key indicator (PVKI, 1 character), PIN verification value (PVV, 4 characters), card verification value or card verification code (CVV or CVK, 3 characters) PINs may be included
  • Longitudinal redundancy probe (LRC) - A character (most Readers do not return this value when switched device card to the presentation layer, And use it only to verify the input internally to the reader.)

    • I hope the data is fake

  • Expiration date
  • CVV
    • / Ul>

    And I'm not sure but I think credit card numbers (or # probabilities) can be calculated using LRC.

    oracle - The fastest way to check if some records in a database table? -

    -
    I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
