Stryker Europe Expands Adoption of SATO's PJM RFID Technology
Medical device manufacturer Stryker Europe has extended its use of RFID to its Swedish distribution center. The DC has adopted SATO's Phase Jitter Modulation (PJM) RFID technology, according to SATO and its health-care partner, Altrax Group, a traceability solutions provider based in the United Kingdom. The PJM technology being used by the DC was provided by Altrax. Stryker Europe has previously implemented the technology at its main distribution centers in the United Kingdom, France, Germany, Spain, Belgium and Italy, following deployments in Australia and New Zealand (see RFID News Roundup: Orthopedic Implant Company Stryker Rolls Out SATO's PJM RFID Solutions Across Europe). PJM RFID is designed to quickly and accurately identify large volumes of tagged items stacked or stored in any physical orientation, according to SATO and Altrax Group.
SATO purchased Magellan Technology Pty Ltd., which invented the PJM RFID technology, in December 2013 (see SATO Acquires Magellan Technology). The company says it is now conducting research into and development of the PJM technology, while expanding its business of implant logistics management solutions in Asia and Europe.
Maxim Integrated Unveils NFC RFID Chip With an I²C interface
Maxim Integrated has announced a new Near Field Communication (NFC) RFID chip that combines an NFC RFID interface (compliant with the ISO 15693 standard) with an I²C interface, so designers can perform secure wireless data communication on their embedded systems without requiring the host microcontroller. The MAX66242 DeepCover Secure Authenticator enables the collection of system data from portable devices, even when the main energy source on the master device is not functional. Suitable for a variety of applications, the MAX66242 is especially useful for applications that require additional external functionality, but that lack the necessary space to place a connector, such as the secure, wireless transfer of medical data or asset tracking, according to Maxim Integrated.
The MAX66242 does not require an external power source. Instead, it integrates an energy-harvesting capability that can be used to power surrounding chips (such as a temperature sensor) to gather data from them. The energy-harvesting capability is connected via the I²C interface, and complements the existing power source in battery-powered devices, thereby extending overall battery life. It features an integrated SHA-256 cryptographic engine that provides symmetric challenge-and-response authentication based on a secret key for data downloads.
The MAX66242's I²C interface port can operate as a master port or a slave port for secure data exchanges, and the chip comes with multiple memory-programmable options which let a user configure a secure master/slave system and set usage limits using the electrically erasable programmable read-only memory (EEPROM) emulation mode to create nonresettable counters. Designers can also utilize the MAX66242 to set up Wi-Fi or Bluetooth connections as a means of securely storing the pairing codes, Maxim Integrated reports; it then provides security for access control and tracking, system alert and wakeup, and the authentication of medical sensors for the secure transfer of personal data.
NXP Semiconductors offers a similar chip, the NTAG I²C (see RFID News Roundup: NXP Announces Commercial Release of NTAG I²C Chip).
