To ensure that terminal testing remains of the highest quality, EMVCo has updated its Level 1 contactless test plan for Proximity Coupling Devices (PCD). It now requires the use of automated tools, which will greatly improve the speed and accuracy of testing, as well as ensure repeatability - a key concern for terminal manufacturers.
Due to the increasing number of contactless products on the market, and the growing need for interoperability, EMVCo has introduced an automated test tool in order to minimise errors or discrepancies associated with manual test procedures.
Fabien Bocquet, Smartcard Systems Manager at TÜV SÜD Zacta, explains: “In order to confirm all of the capabilities of a PCD, it is necessary to implement more tests. In this case it involves numerous additional measurements with specific and stricter cursor positioning. Such an increase could introduce human error if these tests are implemented manually, so the introduction of an automated tool is necessary.
“It is also vital to remember that this is the first time measurements are required on every command sent by the PCD. This might be a challenge for manufacturers, especially if they rely on self-debugging,” concludes Fabien.
Key changes include:
A new test mode added to the DTE - TRANSAC (A & B). This allows the PCD to perform a complete transaction without waiting for any possible PICC answers. DTE must be provided by the manufacturer, with relevant updates to meet the new specifications.
Several tests (TA121 to TA128, and TB121 to TB127) with the PCD must now be conducted using this new DTE mode, which measures the analogue characteristics of the signal, such as the timings and voltage.
Measuring the envelope of the signal emitted by the PCD has been modified. The voltage (V1 for type A, V1 and V2 for type B) is now measured immediately before the falling edge for V1 (rising edge for V2), corresponding to a change of modulation from the PCD.
Measurements must be taken on every command sent by the PCD in the transaction, and not only the first one as previously required. Each position of the operating volume will now include a minimum, nominal and maximum value; calculated from the values measured on all the commands sent by the PCD.
As the use of an automated test tool is now required, all of the above changes, and the cursor placement for measurement, are now performed automatically.
As these changes can be a great burden in terms of cost and time for manufacturers attempting to tackle them alone, TÜV SÜD offers support with both debug and approval testing. With more than 10 years’ experience in EMV-related testing, alongside our Visa and Mastercard testing services, TÜV SÜD’s ability to offer combined support for Level 1 and 2 testing delivers a vital advantage to manufacturers.
