August is Looking Good!
August is almost over and we are looking good for our milestones, which were identified in our July 19 update as (1) releasing the OS for Risk Production evaluation; (2) preforming a manual burn of the embedded secure element chip (eSE), and (3) finalizing the prototype (EV2).
The new version of the OS has been released for evaluation and is in the process of being certified. We were able to manually burn some development chipsets with the new OS version for firmware development and testing. The chipset is a System in a Package (SIP) that includes a controller and embedded secure element. The release of the OS and verifying our ability to manually burn chipsets are necessary steps before we go into production. As we said previously, for data security reasons we can’t update the OS over the air, so we need to confirm we have everything right, and pass security testing, before we move to production. These milestones are important steps in that process.
Speaking of testing, we completed a half-day debug test for EMVCo Level 1 at the testing lab to check our progress on the EV2 prototype. This was a preliminary test in advance of the formal EMVCo process. The EMVCo test is a major milestone that we need to pass in order to certify Pagaré for payment functionality.
So what is EMVCo’s Level 1 certification test? The EMVCo specification defines the physical characteristics, radio frequency interface and transmission protocol between credit and debit cards and a payment terminal. Payment devices must meet these requirements to be used in a commercial environment.
The Level 1 testing and approval includes:
- Digital and analog testing for the electrical, mechanical and communication protocol characteristics of the mobile device, defined within the EMV Contactless Communication Protocol Specification – Book D, version 2.5;
- Interoperability testing to validate the successful interaction between the mobile payment device and a range of EMVCo approved payment acceptance terminals;
- Performance testing of the mobile payment device to ensure optimal transaction times.
The debug lab uses a robot and simulated terminal reader to test the performance of the NFC Antenna. The test bench is configured for testing mobile phones, so using the Pagaré required a bit of manipulation to get it mounted correctly for testing. A small reminder that Pagaré is cutting edge since the testing lab didn’t anticipate a form factor like ours.
We also had to mark the center of the antenna so the communication distance could be accurately measured.
This test was intended to give us an early look at how the design of the NFC antenna performs, so that if any adjustments are needed, they can be made before the prototype is finalized and we move into the formal EMVCo process. It measures reliability of the signal at various distances from the point of the terminal. The testing showed that the antenna needed to be recalibrated to meet the performance requirements. We took the test data and have made changes to the antenna design to improve the performance.
September is almost here and we are looking forward to completing the firmware and having a certified OS. We will provide that information and other updates soon.
