Q11: “How does VeChain work with customers that have already RFID tags in their current supply chain lifecycle? any examples? how does VeChain fit in this process.

Could you explain a bit how the VeChain sensors work from a deployment perspective? as I understood they will operate with NB IoT. Does VeChain supply the underlying infrastructure to have these connected?

How does the information from the sensor get stored in to the decentralized ledger? could you explain this in a few steps?

Last question, a bit personal from engineer to engineer. What was the reason you chose to join VeChain?”

A11: As customers may have existing RFID solutions that have been running for some time, it is easy to integrate VeChain Thor blockchain solution into their system, such as logistics management with RFID. We have many software companies as partners who have a lot of experience in enterprise applications and help to integrate and deploy VeChain blockchain solutions. VeChain offers a variety of sensors including environmental sensors such as temperature/humidity/barometric pressure, inertial sensors such as accelerometer/gyroscope/compass, gas sensors, and GPS/Glonass/Beidou positioning sensors. For different customer requirements, VeChain will give a suitable IoT+Blockchain solution. For example, VeChain’s cold chain sensor, divided into offline and online versions, has been in mass production and available commercially. - Offline temperature sensors use NFC as data transmission interface. It’s easy to use, and the product can be repeatedly used, the cost can be offset. With software optimization, a CR2032 battery can have nearly one year working time for this solution and this battery can be changed to a new one to make another year. - Online temperature sensors can capture and upload temperature data in a real time manner. This solution uses Qualcomm MDM9206 solution, which support NB-IoT and 2G/eMTC. Hash value is stored in the blockchain, while the original data is store in the CHAOS which is a decentralized storage solution developed by VeChain. Lastly, I (Refers to Mr. Gu) joined the VeChain because the team is a passionate, fruitful, and full of ideal teammates.

Q12: How many chips can the machine produce in an hour? And is it suited for big customers? Those NFC/RFID chips really look incredible. Best of both worlds! My question for Gu: have the demo machines been used to produce chips for enterprise clients yet? I imagine they have enough production capacity to fill small orders of under 10,000.

A12: The demo machine in the video can produce NFC + RFID hybrid chips, and is currently in production for one of the French luxury brands. We have already produced more than 20,000 pcs for them. For NFC type chips, our daily production capacity can reach 50k per day for each device. We have two options to increase the manufacture capacity: - Increase productivity by adding more equipment. The equipment is designed and manufactured by ourselves, it is easy to build more. - At the same time, we have been developing NFC + RFID dual-mode chip electric motor equipment to replace the current pneumatic equipment, the estimated speed can be increased by 300% or more. We have built up strong relations with several hardware partners to help us realize the coming large requirements. So please don’t worry about the production capacity.

Q13: What info can at the time being, be recorded? How scalable is the chip, in integrating new metrics to measure down the line?

A13: RFID/NFC chips only store the unique ID of the product as well as the key pair for its identity. Information relating to the product such as description, logistics can be customized based on the needs and requirements from the clients. For example, if geographic data need to add to the temperature IoT device, we just need to add the module which can capture location data, not too much modifications in the backend.

Q14: Considering you can get creative with RFID chip placement on a product (particularly, apparel), I’m assuming there will be an anti-theft benefit once it reaches a client’s store. Example: Someone tries to walk out of an H&M store with a stolen sweater, but the sensor detects this. Is this being considered in in your operations for greater customer utility?
