28. Abbreviations
29. Glossary
Modulation index — Defined as the voltage ratio (V
max
 V
min
) / (V
max
+ V
min
).
Load modulation index — Defined as the voltage ratio for the card
(V
max
 V
min
)/(V
max
+V
min
) measured at the card’s coil.
Initiator — Generates RF field at 13.56 MHz and starts the NFCIP-1 communication.
Target — Responds to command either using load modulation scheme (RF field
generated by Initiator) or using modulation of self generated RF field (no RF field
generated by initiator).
