Best practice - the steps to EMV Contactless level 1 approval
Before deploying contactless payment terminals, POS providers must face the challenges of product certifications.
EMV capable devices must be submitted to several approvals to prove compliancy with international payment and security standards.
The first step is to pass EMV CL1 approval. It consists in series of tests to evaluate the communication protocols and interoperability
of the contactless reader, in regards with EMVCo's analog and digital requirements. The quality of the RF antenna design is a major element in the success of this certification.
RF antenna design
Terminal manufacturers must face the hurdle of designing the RF antenna when they build a new contactless payment solution. Hardware manufacturing and antenna design require specific
knowledge and specific tools such impedance bridge or oscilloscope.
They must also set specific registers with certain values in order to define the operating volume of the antenna according EMVCo's requirements.
In addition to the physical characteristics, the CL1 digital stack must be implemented in order to test the device against EMV CL1 approval.
CL1 digital stack, debug and approval
As provider of embedded software, Alcinéo manages the implementation of CL1 software stack into customer's hardware platform and performs validation campaigns based on digital test cases.
Tests are performed in conditions similar to CL1 approval.
Alcinéo provides the digital tool to set an integrated device testing environment at the laboratory, allowing to modify settings in registers if necessary.
It also offers GUI interface to the operator, and is compliant with EMV Device Testing Environment requirements.
Once the device has successfully passed CL1 debug session, the terminal provider should submit the same sample to EMV CL1 Type Approval, preferably within a short period of time
to mitigate the risks of modifications of the testing materials (cards or mobiles used for testing).
Towards greater interoperability
EMV Contactless Level 1 type approval is evolving and several documents recently released on EMVCo website or by Mastercard, are modifying the certification strategies and processes.
Starting July 1st 2018 the EMV level 1 certification process includes an interoperability testing session available at accredited laboratories. Contactless acceptance devices can be tested
using a range of referenced cards and mobiles similar to those deployed in the field.
This will result in a reduction of the interoperability tests operated by payment schemes
(such as Integration or Combination for Mastercard) during level 2 certification process.
The EMV interoperability test session will become mandatory from January 1st 2019, in addition to the analog and digital testing sessions, to increase payment systems' interoperability.
