Notification Group 0x03 - EMV L2 (EMV Only)

Notification Group 0x03 is reserved for EMV L2 notifications that support Command Group 0x03 -
EMV L2 (EMV Only, Extended Commands Only). For more information about the general flow of
EMV transactions, see section 7.4 Command Group 0x03 - EMV L2 (EMV Only, Extended
Commands Only).

6.2.1 Notification 0x0300 - Transaction Status / Progress Information

The device sends the host this notification to report progress during an EMV transaction the host has
initiated using Extended Command 0x0300 - Initiate EMV Transaction (EMV Only). The granularity
of notifications is designed to give specific information about transaction steps that involve interaction
with either the cardholder or the host. More information about when the device sends this notification to
the host can be found in the documentation for that command.
Some devices also send this notification outside the context of an EMV transaction to more generally
notify the host that a card has been removed.
The behavior of this notification is partly driven by the settings in Property 0x6D - EMV Contact
Notification Configuration (Contact Only).
