None This bulletin is intended to clarify terminal behaviour during application selection to avoid potential interoperability issues that may occur in the event that the terminal also supports non-EMV applications. Proposed Changes Please make the following change to EMV '96 Integrated Circuit Card Specification for Payment Systems Version 3.1.1 Part I, Section 2.1.1 Stages of a Card Session and to EMV 2000 Integrated Circuit Card Specifications for Payment Systems Version 4.0 Book 1 Section 2.1.1 Stages of a Card Session Change step 3 to read: 3. Application selection and execution of the transaction(s) Please make the following change to EMV '96 Integrated Circuit Card Specification for Payment Systems Version 3.1.1 Part III, Section 1 and to EMV 2000 Integrated Circuit Card Specifications for Payment Systems Version 4.0 Book 1 Section 8.1 Overview of Application Selection: This document contains proprietary and confidential information of EMVCo LLC.

Change the first sentence to read: During an EMV card session as defined in section 2.1.1, application selection using the commands and techniques described in sections 7 and 8 of this book shall be the first process performed immediately after contact activation/reset of the card and prior to the first application function. If a proprietary processing session (including any proprietary application selection method) is performed immediately before or after an EMV card session, there is no requirement to remove/reinsert the card between the sessions. However, if proprietary processing occurs before the EMV card session, the card contacts shall be deactivated before starting the EMV card session. Change the 3rd paragraph to read: It is not recommended that the ICC and the terminal use implicit selection as defined in ISO 7816, as it is not useful in an interchange environment. If used, it shall be performed outside the EMV card session as defined in section 2.1.1. This document contains proprietary and confidential information of EMVCo LLC. Copyright © EMVCo LLC 2004
