Security code readability

14 votes

Our team has a difficult time quickly matching up the 4 digit security code with the guardian receipt. We have a few ideas and hoping that one might be a possibility to make it easier to read:
1. Switch the letters to upper case.
2. Use a 3 digit alpha-numeric code with numbers and upper case letters.
3. Maybe space out the digits a little bit.
