1  how i should go about generating the scratch card pin and serial nu mber, cos they will have to enter both the serial and pin during pyaments

2 how i should go about authenticating the pin and scratch card number in the most secured manner

Hi,

From your description, it seems that you want to generate the scratch card number and pin number in your system, right?

If so, I suggest that you can create a data table in your database with two columns, one is for scratch card number and another is for the pin number. You can generate the scratch card number and pin number by producing a new guid, and insert them into data table. So once the user enter the scratch card number and pin number, all those information will be authenticated by query for the corresponding row in that data table.

Thanks.

When you generate the scratch card pin and number and after you give them to a user you can has them before storing them in the database, this will mean that people looking at your database will not be able to work out the real card number or pin. When a user enters the scratch card number and pin you can has these two and then compare them agaisn't the hased values in the database when looking for a match. Let me know if that works for you.

Cheers
