Interoperability Bulletin No. I0092

EMV® Interoperability Bulletin No. I0092 First Edition January 2024 Field Issue with T=1/D=4 cards at Automatic Fuel Dispensers Applicability The following interoperability issue has been reported to IWG. EMVCo Identifier Issue Identifier Status Date Opened Description Findings I0092 Transaction Severity ●=High ○ I0092 Volume Severity Resolution in progress – EMVCo, Payment System =Low Feb 15, 2023 EMVCo was made aware of an interoperability issue in the US market affecting Automated Fuel Dispensers (AFD) installed in Nidec Instruments product when they are used with chip cards using T=1 D=4. The issue causes the terminal to time out and lock the card inside the reader. This is an issue as the merchant must shut down the pump to release the card, causing acceptance issues in the field. The root cause is the S(IFSreq) communication block sent by the ISO module that is called prior to the EMV transaction (the AFD accepts non- EMV ISO7816 cards as well). This block, only used when using T=1 protocol, is sent without applying the bit rate adjustment factor of D=4 resulting in a transmission error. The waiting time for the module between retries is quite long resulting in the payment application to time out the transaction. This proprietary “ISO module” was not activated by Nidec Instruments on samples supplied for the EMVCo Type Approval as assumed to be incompatible with the testing tools. Terminal Information Nidec Instruments (previously known as Sankyo) IFM330-0600A LoA # 13044 0414 400 21 FMT. Corrective Action Preventative Action Additional Comments: Impacted Nidec Instruments terminals need to be updated with a firmware fix from Nidec Instruments pending EMVCo testing. According to Nidec Instruments, the card reader version of the AFD which requires the update is: version 4464-01S or before. Version 446401U or later should have no issues. EMVCo will release a Type Approval Bulletin with guidance on how to best manage product type approvals when products support proprietary and additional protocol sequences that the EMVCo test tool does not accommodate.
