Read your electricity meter with an Android smartphone
The companies have worked together to demonstrate a secure postpaid electricity meter which uses a near field communication (NFC) wireless link to read the meter.

“It lets consumers use NFC smartphones or other devices to securely read their own meters and transmit encrypted data to utility companies to pay their bills,” said Bruno Baylac, director and general manager of Freescale’s Metering, Medical & Connectivity business unit.
The demonstrator is based on Freescale’s Kinetis MK30X256 Cortex-M4 microcontroller running at 100MHz (built on an ARM Cortex-M4 core).
Co-developed by Freescale and INSIDE Secure, the postpaid meter demonstrator which uses the VaultIC 460 security module and the MicroRead 3.4 NFC controller and Open NFC protocol stack from INSIDE Secure.
The FIPS140-2 Level 3 certified VaultIC 460 security module enables comprehensive security functions such as mutual authentication, certificate generation and verification, data encryption/decryption and management of secure cryptographic key storage.
“Providing adequate security in electricity meters to prevent fraud while enabling customers to read their own meters presents several challenges,” said Christian Fleutelot, general manager and executive vice president for digital security at INSIDE Secure.
