Why Palindromes?

Palindrome totals serve as a simple but effective fraud detection mechanism:

  • Easy to remember—just check if it reads the same both ways
  • Any modification to the total breaks the palindrome pattern
  • Instantly verify charges on your bank statement
  • No need to keep paper receipts for comparison
