If you are doing online business I am sure you have researched a a certain customer that looks questionable. One trick I learned is to put their email in Facebook and see if they have a profile. If not, then most likely it’s a fake or new email used for fraud. If this isn’t enough then try to call the number they gave when signing up. If they are out of the country this can be double tricky for the first to. Another trick is to check the card type:
0 – ISO/TC 68 and other future industry assignments
1 – Airlines
2 – Airlines and other future industry assignments
3 – Travel and entertainment and banking/financial
4 – Banking and financial
5 – Banking and financial
6 – Merchandising and banking/financial
7 – Petroleum and other future industry assignments
8 – Healthcare, telecommunications and other future industry assignments
9 – National assignment
If it’s not a bank card, that should be cause for concern.
Next is to check the type:
The first six digits of a card number (including the initial MII digit) are known as the issuer identification number (IIN). These identify the institution that issued the card to the card holder.
If the type does not match the country that is cause for concern.
