Error
Code
Description
Reason for Error and Suggested Error Handling
42h
Card Generated
AAC
The card declined the transaction by sending an AAC instead of a TC.
43h
Card Generated
ARQC
This error code is returned if the card generated an ARQC and the terminal/reader
was configured as “Offline Only”; therefore the card was DECLINED.
44h
SDA/DDA Failed
(Not Supported
by Card)
Card did not indicate support for the correct authentication method and date
authentication failed. For Visa, when DDA is required, the card must indicate support
for DDA in AIP. If this support is not indicated then the transaction fails and this
error code is returned.
50h
SDA/DDA/CDDA
Failed (CA Public
Key)
Data authentication failed due to missing CA public key.
Retrying the transaction does not correct the error until the missing CA public key
problem is corrected via key management commands.
51h
SDA/DDA/CDDA
Failed (Issuer
Public Key)
Data authentication failed due to a problem in recovering the issuer public key from
the card data. Data on the card may be incorrect or the reader has the wrong CA
public key.
The transaction continues to fail until the issuer public key and the CA public key are
correct.
52h
SDA Failed
(SSAD)
Data authentication failed during SSAD. Retrying the transaction does not correct
the error.
53h
DDA/CDDA Failed
(ICC Public Key)
Data authentication failed during attempted recovery of ICC public key. Retrying the
transaction does not correct the error.
54h
DDA/CDDA Failed
(Dynamic
Signature
Verification)
Data authentication failed during dynamic signature verification. Retrying the
transaction does not correct the error.
At this point, the amount has been deducted from the card balance.
55h
Processing
Restrictions
Failed
The processing restrictions step as defined in EMV specifications failed. This could
be due to incorrectly set configuration. Retrying the transaction does not correct the
error until the EMV configuration is corrected.
56h
Terminal Risk
Management
(TRM) Failed
The terminal risk management step as defined in EMV specifications failed. This
could be due to incorrectly set configuration. Retrying the transaction does not
correct the error until the EMV configuration is corrected.
57h
Cardholder
Verification Failed
The cardholder verification step as defined in EMV specifications failed. This could be
due to incorrectly set configuration. Retrying the transaction does not correct the
error until the EMV configuration is corrected.
58h
Terminal Action
Analysis (TAA)
Failed
The terminal action analysis step as defined in EMV specifications failed. This could
be due to incorrectly set configuration. Retrying the transaction does not correct the
error until the EMV configuration is corrected.
59h
Card Expired
(Interac)
This error code is sent to the terminal if the current date of the reader is greater
than the expiration date of the card. This status code is only valid for qVSDC cards.
(Terminated)
5Ah
Cardholder
Verification Failed
(Interac)
The cardholder verification step as defined in EMV specifications failed. This could be
due to incorrectly set configuration. Retrying the transaction does not correct the
error until the EMV configuration is corrected. (Terminated)
61h

never reported during a transaction.
