Electromagnetic Disturbance (EMD) and ISO/IEC 10373-6/A2
Interoperability issues may result from contactless smart card (PICC) generated EMD. The card communicates by load modulation, but changes in a card's power consumption also result in unintended load modulation. Sometimes the effect is significant enough to result in false card response detections by the reader.
As a result, technology and testing standards have evolved to address the Electromagnetic Disturbance (EMD) characteristics of contactless smart cards – ISO/IEC 14443-2:2010/Amd.1: 2011, ISO/IEC 14443-3:2011/Amd.1: 2011 and ISO/IEC 10373-6:2011/Amd.2:2012.
Changes to these standards have included:
1. Ensuring that EMD emissions of the PICC respect a "Low EMD period" of a specific duration and max EMD level just prior to the card's response.
2. Readers implement recovery procedure to ensure the permitted high EMD from the PICC is not acknowledged by the reader in lieu of a card response.
KEOLABS Testing Laboratory provides ISO/IEC 10373-6/A2 testing services to assess the conformity of cards (PICC). Testing is conducted on a specially designed and verfied EMD testing environment. This tesint environment is the result of an extensive cross-validation program conducted by KEOLABS and leading smart card and component manufacturers. The EMD test environment is designed and implemented to enable verification of its EMD characteristics and capacity to generate and calibrate a clean, precise carrier signal for testing.
KEOLABS offers EMD profiling in accordance with standards ISO/IEC 14443-2:2010/Amd.1: 2011, ISO/IEC 14443-3:2011/Amd.1: 2011 and ISO/IEC 10373-6:2011/Amd.2:2012. This testing makes it possible for suppliers of PICC components or integrated devices to obtain a profile of their tested samples.
The laboratory is an accredited testing facility for the smart card industry.
Products implementing ISO 14443 may require testing under other standards. The Testing Laboratory offers services for qualification of porducts in the following areas and for the following standards:
