Fallback Indicator

This field indicates the reason why a chip-capable terminal processed the transaction using the magnetic strip of a chip-capable card for Visa, MasterCard, or Discover. The field will be blank when a fallback does not occur.

• T: Indicates the transaction was processed as a magnetic strip transaction due to a malfunction.
• E: Indicates the transaction was processed as a magnetic strip transaction as there was no common application supported by both the chip and the terminal in the course of communicating.
