Raspberry Pi enthusiast may be interested in a new DIY project published to the Hackster.io website this week, providing details on how to build your very own Raspberry Pi blockchain RFID scanner. Enabling those interested to send RFID tag data to the EOS blockchain for novel supply chain, manufacturing, tracking and access control applications. The project uses a Raspberry Pi as an IoT device and the EOS blockchain as the global distributed platform.
The Internet of Things device is capable of scanning a wide variety of different RFID chips for keycards, fobs, patches, tags and more. The tags can be used to uniquely identify the items they are attached to in order to provide proof of location and time in supply chain, manufacturing, asset tracking and access control applications.
“Everything you need to build this open source scanner and to access your scanned tag data on the blockchain is provided, including the node.js software, pre-deployed smart contract/dApp, blockchain account and private key. A simple web-application is available to facilitate real-time demonstration of end-to-end scanning, transacting and retrieving of real IoT data on a blockchain.”
EOS was selected for the project because it offers these key features:
– EOS offers fast transaction times: a scanned tag appears on-chain within 2 seconds typical.
– EOS has no transaction fees. The blockchain resources are purchased up-front and one-time only. The IoT device can then transact within allocated resources without incurring additional fees.
– EOS transactions are efficiently packed binary structures minimising bandwidth requirements.
– EOS uses the same globally recognised and hardened security standard as other blockchains like Bitcoin and Ethereum.
