What kind of barcode scanner do I need to use ChurchTrac's attendance scanning feature?

ChurchTrac's barcode scanning feature requires a scanner that supports the Code 39 (also known as 3 of 9) barcode format. Many scanners support this format natively. However, you may need to configure the software that came with your scanner to Code 39 format. See your scanner's documentation for instructions. If you're looking for a barcode scanner, many are available on ebay or Amazon for as little as 15 to 20 dollars.
