STMicroelectronics Reveals Compact Contactless Module with boostedNFC(TM) Technology, Extending Secure Payment to Wearables
October 19 2017 - 9:02AM
- Market-unique solution overcomes space constraints by
integrating a miniaturized contactless radio booster with a secure
microcontroller in the same package
- Industry-leading solution ensures compelling user experience
with small-size antenna
- System-in-Package meets security and card-industry standards
and is supported by development ecosystem including software and
tools
Geneva, October 19, 2017 - STMicroelectronics (NYSE:
STM), a global semiconductor leader serving customers across
the spectrum of electronics applications, is delivering the
technology for easy and secure contactless transactions using the
ever more popular wristbands or fashionwear like watches or
jewelry. The market-unique ST53G System-in-Package solution
combines the Company's industry-leading expertise in Near Field
Communication (NFC) and secure-transaction chips.
As consumers become increasingly comfortable with making secure
transactions using their smart devices, traditional card
manufacturers want to extend their offers into contactless wearable
products for uses such as payments, ticketing, and access control.
These can be difficult to implement within tight size and cost
constraints, because conventional separate NFC-radio and security
chips demand extra space and complicate design. In addition,
wearable form factors reduce the options to small antennas that can
restrict communication performance.
ST's new ST53G System-in-Package overcomes these barriers by
combining a miniaturized and enhanced NFC radio with a secure
banking chip in one compact 4mm x 4mm module. The Company's
industry-leading, proprietary boostedNFC(TM) technology allows
wearables with small antennas to deliver a great user experience
when interacting with card readers over typical contactless
distances.
The simplicity of this all-in-one module helps card
manufacturers to quickly introduce functional and attractive
wearables that can range from fashion items to one-time devices
like event wristbands. ST offers an extensive development
ecosystem, including radio-tuning tools and pre-defined antenna
configurations. The ST53G meets all relevant card-industry
standards, including EMVCo(TM) compliance, ISO/IEC-14443 NFC card
emulation, and MIFARE® ticketing specifications.
The ST53G completes ST's range of System-on-Chip products, and
can host ready-to-use STPay smartcard operating systems and
optional VISA/Mastercard/JCB-certified banking applications
pre-loaded on the secure microcontroller.
"By making secure transactions possible on wearables ranging
from one-time devices to fashion items, our new chip module
broadens consumer access to convenient, frictionless banking and
ticketing," said Laurent Degauque, Secure Microcontroller Division
Marketing Director. "We are already working with customers to
develop new ST53G-based products and support these market-friendly
use cases."
Engineering samples of the ST53G System-in-Package in the 4mm ×
4mm WFBGA64 package are available now. Full production is scheduled
to start in Q1 2018. Please contact your local ST office for
further information and pricing options.
Further technical details:
The secure banking chip contained in the ST53G System-in-Package
leverages ST's proven ST31G480 secure microcontroller for
high-performance smartcard applications, which is based on the Arm®
SC000 SecurCore® processor. It features a secure architecture with
a NESCRYPT coprocessor for public-key cryptography and hardware
accelerators for algorithms like AES and triple-DES. Extensive
anti-tamper protection including an active shield, environmental
monitoring, a unique serial number for each die, and protection
against numerous other attacks is also built-in. These features
complement software-based security running on the SC000 core to
ensure the strongest possible protection for users'
credentials.
The contactless IC is the STS3922 RF booster, which uses
active-load modulation (ALM) to maximize transaction range and
omnidirectional radio performance in card-emulation mode. This
enables wearable devices to be easy to use, with equal or better
device-to-reader positioning tolerance than conventional
contactless smartcards, even though a smaller antenna is used.
Using ST53G contributes to final device cost optimization, as small
antennas can be etched onto the PCB at almost zero additional cost.
In some cases, a challenging metallic case can itself be used as
part of the RF antenna.
In addition, automatic power and gain control, configurable
sensitivity, and configurable signal/reader-field phase difference
ensure consistent communication over all ranges while enhancing
interoperability with different types of readers and terminals
including various types of transportation ticketing systems. The
STS3922 has inherently low power consumption, and a dedicated
secure-microcontroller wake-up output allows the ST53G
System-in-Package to maximize battery life by powering down when
not in use.
The ST31G480 secure element is EMVCo and Common Criteria
certified, and the STS3922 is ISO/IEC 14443 and EMVCo Level 1
compliant, ensuring full interoperability with existing payment and
ticketing infrastructures.
In addition to radio-tuning tools, ST also provides Software
Development Kit (SDK) platforms for implementing card services on
various wearable-device architectures, as well as reference design,
expansion boards, and pre-certification services to help simplify
development and accelerate time to market.
