How to Write Redeem Codes

From gift cards to bottle-cap contests, redemption codes provide companies with a secure way of delivering intangible inventory to their customers. Codes for customers to redeem tend to be alphanumeric strings ranging from four to 16 characters. Ideally, most combinations of letters and numbers will not coincide with the redeem codes so that fraudulent users do not often succeed when attempting to guess codes. Learning to write redemption codes allows you to distribute and control intangible inventory such as gift card balances.

Instructions

- 1
  Choose an even number between four and 16 for the length of your redemption code. Select a longer code if you plan on distributing a large number of codes.
- 2
  Generate a large number of random codes. Use a random alphanumeric string generator (see References for an example) to simplify the generation process.
- 3
  Enter the random redeem codes into a database program, such as SQL.
- 4
  Run a report script to identify any potential duplicate codes. Remove the duplicate codes so that each code occurs only once.
- 5
  Assign a redemption value to each code. Identify a column in your database as the redemption value. Enter the redemption value for each code in the appropriate column next to the redeem code.
