comment Check for database tampering
The goal is to be alerted if any data has been altered from the original. Also to make it (virtually) impossible to create a hash with malicious data

comment Security concerns with pre-pay system
Wow, great comments thx. Initially the pre-pay system will be site specific, codes can't shared across sites. Franchise or multiple sites will require more thought I think. The code is loaded into an app and as a customer purchases product it is deducted from the total.

Yes, the codes are retailer specific. I have another table that tabulates all transactions for each code. Thanks for your comments.
