We are interested in the second path, and what can we see on it?:
It can contain up to 40 characters:
First there is a starting symbol – %
Then there is Pan – up to 19 digits, in our case it is a card number.
It includes the code of the emitter card (Iin: Issuer Identification Number) (up to 6 characters), which in turn consists of:
The main industrial indoder (MII: Major Industry Identifier) (up to 2 characters):
0: Response for future use by the ISO/TC 68 standard.
00: not for issuing cards
1: Airlines.
2: Airlines and for future use.

6: Banks and Merchi.
7: Fuel industry.
8: telecommunications and for future use.
89: telecommunications and for private agencies.
9: reserved for national use.
Next is the emitter code (II: Issuer Identifier), up to 5 digits, in some cases, innn is written or its size if it goes beyond the ISO. If MII is 9, then the first three digits are the country’s code (it is not of interest to us)
Then there is an individual account number (IAI: Individual Account Identification), up to 12 digits, is appointed by the organization that issued the card
Then there is one digit used to verify the number and other information, is combed out according to the formula: (I will lay out the formula a little later)
PAN Mastercard consists of not more than 16 characters, and VISA has 13 or 16, including a test figure.
Next is the separator, one symbol – =
In some cases, the country’s code (if PAN begins with 59), it is determined in ISO 3166: 724 for Spain, 840 for USA, etc.
Then, in most cases, there is a date for the end of the map in the GGMM format (Godmes).
Then there is a three -sized service code, it consists of:
The first digit determines where you can use the card:
0: Responced for future use.
1: For international use.
2: for international use, with restrictions.
3: reserved for future use.
4: Responced for future use.
5: only for internal use, except for pre -agreed agreements.
6: only for internal use, in addition to pre -agreed agreements, with restrictions.
7: Not for payment, except for pre -agreed agreements.
8: reserved for future use.
9: for verification.
The second digit determines the conditions of use/authorization of the card (Authorization Processing):

5: Responced for future use.
6: reserved for future use.
7: reserved for future use.
8: reserved for future use.
9: reserved for future use.
The third digit determines the services and conditions of the PIN requirement
0: Without restrictions, you need PIN.
1: without restrictions.
2: goods and services (not cash).
3: ATM just needs PIN.
4: Only money.

6: without restrictions, PIN on demand.
7: goods and services (not cash) and PIN on demand.
8: reserved for future use.
9: reserved for future use.
Then there is a hash PVV (PIN Verification Value), 5 characters, followed by symbols reserved for use by the emitter. And at the end of all there is a final symbol -?
Symbols of the beginning and end of the line are official information, which is automatically added when recording and removed when reading. They should not be indicated in the input fields during recording.
