Version 2.7 of EMV contactless payments specifications is now available on EMVCo website. You will find on the website the version 2.7 of Book A, Book B, and Books C-2 to C-7.
In the meantime, 2 documents have been revoked from the specification documentation :
Book D Communication Protocol was replaced with the Contactless Interface specification – defining the communication rules between a contactless card and a contactless reader or terminal.
Book C1 has been removed from the list of EMV contactless kernels. This book used to be the reference for the development of EMV contactless kernel for JCB and PayWave transaction types.
The purpose of EMVCo is to provide interoperable and common rules for EMV contactless implementation in a POS system. It allows terminal manufacturers to whether update their existing materials with current standards, or build new products developed with the latest requirements.
Moreover, in accordance with the EMV contactless Interface Specification v3.0 released in February, the latest version 2.6b of test cases, test bench and DTE requirements must be applied during the device testing process.
POS providers must ensure that their device testing environment is compliant with the latest testing requirements.
Additionally, EMV Contact Terminal Type Approval version 4.3a will soon expire to the benefit of the new version 4.3c. Starting July 1st, EMV contact terminals submitted to EMV L1 type approval, shall comply with the 4.3c version.
