 * Hi, I noticed Square adds the **checkout postal code** to the credit card field
   automatically but the **credit card postcode** field can be changed. Are either
   of the two fields used for AVS? Would it be better to add a note on the credit
   card field that this post code needs to be linked to the credit card?

 * Hey there!
 * The postal code that Square adds in their card fields area in WooCommerce checkout
   is used to do their fraud detection. You can customize to add any note you would
   like to your checkout fields.
