1. Product description:
Infinity NFC+ prepayment gas meter (Near Field Communication) complies with the STS international prepaid standard. It integrates the latest NFC smart chip to realize two-way communication. An internal valve helps to achieve prepayment and high-level security services.
It follows the worldwide unique STS prepayment standard, which is open and secure, reducing the gas companies' reliance on meter providers, meanwhile greatly facilitating their third -party sales network expansion.
Infinity NFC+ prepayment gas meter reserves the lnfinity IoT communication module interface, supporting future loT upgrade with a variety of IoT communication modules on demand, therefore realizing cost-effective transformation to smart functions such as remote monitoring, remote valve controlling and post-paid billing services.
2. Features:
High resolution metering
NFC 2-way communication
STS token-based payment mode Internal valve
Temperature compensation(optional)
Field replaceable battery pack
Various of anti-tamper and safety protection mechanisms
IoT module interface reserved
3. NFC:
Integrating the latest NFC smart chip, NFC+ realizes the functions of near-field pointto- point communication, contactless card and reader.
Swiping card will activate two way communication, complete meter reading and recharging operations. According to multiple business requirements, an interal valve is integrated to achieve the prepayment function.
4. STS:
Comply with the STS international prepayment standard that widely accepted by international utility companies and meter
manufacturers.
Use a 20-digit token as prepaid medium, supporting multiple channels such as NFC cards, mobile APPs, text messages, scratch
cards, etc.
Enhanced encryption key management system to allow for distributed key management using multiple key management centers
worldwide.
5. Compliance:
MID B+D Certified
EN 1359 and OIML R137
ATEX approved
6. IoT Module Interface Reserved(Optional):
Thanks to the modular design concept, the online adaptation of GPRS, NB-IoT, LoRaWAN, Sigfox and other wireless communication networks can be realized through the addition of diferent communication modules at factory, achieving realtime monitoring, remote valve controlling and post-payment billing services.
