Message, and terminates the transaction
b) If the Risk Management process determines the transaction is too risky to approve, the device
sends the host Notification 0x0300 - Transaction Status / Progress Information to report Data
Error / Transaction Error, followed by Notification 0x0304 - Transaction Result Message,
followed by Notification 0x0301 - Display Message Request with message
notify the cardholder, and terminates the transaction.

report Transaction Progress Change / Generating First Application Cryptogram. The device
sends the host Notification 0x0300 - Transaction Status / Progress Information reporting
Transaction Progress Change/ Card Action Analysis.
18) If the device is NOT configured as Online-Only Terminal Type [see Appendix C EMV Terminal
and Application Settings (EMV Only)] and the Risk Management processes determined the
transaction is OK to perform offline, the device reports the transaction result to the host as follows:
a) The device sends the host Notification 0x0300 - Transaction Status / Progress Information to
report Transaction Progress Change / Transaction Complete.
b) The device sends the host Notification 0x0300 - Transaction Status / Progress Information to
report End of Transaction and either Transaction Approved or Transaction Declined, then
sends the host Notification 0x0301 - Display Message Request with message
to notify the cardholder.
DECLINED
c) The device ends the transaction by sending the host Notification 0x0304 - Transaction Result
Message, which contains transaction details the host should save for later verification. The
transaction result message indicates whether the host must prompt the cardholder to provide a
signature.
19) If the device is configured as an Online Only Terminal Type [see Appendix C EMV Terminal and
Application Settings (EMV Only)] or the Risk Management processes determined the transaction

a) The device sends the host Notification 0x0300 - Transaction Status / Progress Information to
report Transaction Progress Change/ Online Processing, followed by Notification 0x0303 -
ARQC Message.

Contactless Quick Chip feature (see Table 1-2) and whether the host specified Quick Chip as an
Option when it started the transaction:

Progress Change / Transaction Complete, followed by Notification 0x0300 - Transaction
Status / Progress Information to report End of Transaction / Transaction Declined.
ii) The device sends the host Notification 0x0301 - Display Message Request with message
REMOVE CARD
iii) The host should then process the ARQC Message data, including replacing the default
amount with the final transaction amount, and should coordinate with the transaction
processor to retrieve a final transaction result. Because in this case the device is not involved
in determining the final transaction result, it does not send a notification to the host to show
