We have materials arriving constantly, and sometimes we don’t realize something is missing until the crew needs it. I heard that this might be what the tags could help with. Could RFID help at receiving?

Answer: Yes, and that’s where I think RFID can deliver value pretty quickly for you. The goal is to catch problems when materials arrive, not days Yes, and that’s where I think RFID can deliver value pretty quickly for you. The goal is to catch problems when materials arrive, not days later when someone needs them. If materials are tagged before shipment, RFID can help verify what actually showed up instead of relying solely on paperwork and manual checks.What I like about this use case is that it creates visibility right from the start. You can associate materials with a supplier, project, or installation area and know they’ve actually been received. Because let’s be honest, the expensive part usually isn’t the missing component. It’s discovering that it’s missing when the crew is ready to install it. RFID helps move that discovery point much earlier, when you can still do something about it. ... continue reading

We’ve installed RFID portals before, and sometimes they seem a little too good at their job. How do you make sure you’re reading the items that actually passed through a checkpoint and not everything sitting nearby?

Answer: I’d actually challenge the premise a little bit, because this isn’t usually a technology problem. It’s a design problem. A lot of people think RFID I’d actually challenge the premise a little bit, because this isn’t usually a technology problem. It’s a design problem. A lot of people think RFID success means reading as many tags as possible. In reality, what you want is confidence in the event you’re trying to capture. For example, if you’re managing a tool crib, you don’t care that the reader saw a tool sitting nearby. You care that a tool actually left the tool crib. Those are two very different things. That’s why so much of the work goes into reader placement, antenna positioning, power settings, and understanding how people and materials actually move through the space. Then the software helps by filtering out the noise and turning raw reads into meaningful events. My advice is always to start with the business question. What are you trying to know for certain? “This tool left the crib.” “This pallet entered the site.” “This cart moved into the laundry.” Once you’re clear on that, you can design the read zone around the event instead of just trying to maximize read range.In my experience, the best RFID deployments aren’t the ones that read the most things. They’re the ones that give you the highest confidence in what actually happened. ... continue reading

Can we embed RFID in precast concrete and still read it after the component has been installed? Have you done anything like that before?

Answer: Surprisingly, yes, you can, and that’s actually what makes your question so interesting.Most people think about RFID as something you use during manufacturing or delivery. Surprisingly, yes, you can, and that’s actually what makes your question so interesting.Most people think about RFID as something you use during manufacturing or delivery. But with precast concrete, the real value can continue long after the component has been installed.The key is selecting the right tag and placing it correctly. We say this a lot, but I cannot emphasize it enough how important this step is. Since concrete, moisture, and reinforcing steel can all affect RF performance. But when that’s done properly, the tag can serve as a permanent digital identity for that specific component.So years later, instead of wondering “Which beam is this?” or digging through construction records, you can connect that component directly to manufacturing data, quality inspections, installation records, and even future maintenance information. To me, that’s the bigger story. You’re not just tracking a component through construction. You’re creating a digital thread that stays with that asset throughout its lifecycle. ... continue reading

We grow multiple varieties and batches at the same time. Can RFID help us keep track of exactly what’s growing where?

Answer: Let me put it this way: if someone walked into your growing area and asked, “Which batch is this, when was it planted, and where Let me put it this way: if someone walked into your growing area and asked, “Which batch is this, when was it planted, and where has it been?” how quickly could you answer?That’s where RFID can help.The nice thing is that you’re not locked into tracking everything at the plant level. Some growers track trays, some track benches, some track entire batches. It really depends on how the operation runs. What RFID does is create a reliable connection between the physical material and the information about it. So when something gets moved, transplanted, or shifted to another area, you’re not relying on someone remembering to update a spreadsheet or replace a label. For a lot of growers, the value isn’t just knowing where things are today. It’s being able to answer questions quickly when something unexpected happens. Which batches were affected? Where did they go? What stage were they in? The right level of tracking depends on the operation, but RFID can make those answers a whole lot easier to find. ... continue reading

We track treatments, vaccinations, and breeding information today, but matching all of that data to the right animal still feels pretty manual. Can RFID actully make that any easier, and if so, how?

Answer: Yes, absolutely. I like to think of RFID as giving each animal its own digital identity. Instead of reading a tag number, writing it down, Yes, absolutely. I like to think of RFID as giving each animal its own digital identity. Instead of reading a tag number, writing it down, and then looking up the right record, you simply identify the animal and the system pulls up the correct information automatically. Whether you’re recording a vaccination, treatment, breeding event, or weight, you’re working directly with that animal’s record. The bigger the herd gets, the more valuable that becomes. It reduces manual data entry, helps avoid mistakes, and makes it much easier for multiple people to consistently connect the right information to the right animal. ... continue reading

I’ve heard people say RFID data is only as good as the software interpreting it. Are companies spending too much on readers and tags and not enough on the intelligence layer?

Answer: I think there’s some truth in that, but I’d be careful not to swing too far in either direction. At the end of the day, I think there’s some truth in that, but I’d be careful not to swing too far in either direction. At the end of the day, RFID follows the same rule as every other data system: garbage in, garbage out. The smartest software in the world can’t make bad data trustworthy. If you’re not reliably capturing what’s happening in the physical world, you’re just analyzing noise faster. That’s why I don’t really see it as a hardware-versus-software discussion. You need both. The RFID infrastructure is what creates the digital representation of what’s actually happening, where assets are, when they moved, what passed through a process. Then the software turns those data points into decisions, workflows, and insights. What I do see sometimes is companies getting excited about dashboards, AI, analytics, and digital twins before they’ve established a reliable data foundation. In my experience, that rarely ends well. If people stop trusting the underlying data, they eventually stop trusting the system. So my advice is to think about it as a stack. First, make sure you’re capturing high-quality, reliable data from the physical world. Then let software, analytics, and AI build value on top of that foundation. The magic isn’t in the hardware alone or the software alone. It’s in how the two work together. ... continue reading

How does this actually work when hundreds of employees are picking up and returning uniforms every day?

Answer: Think about what happens in a traditional uniform room. People line up, someone checks uniforms in and out, updates records, answers questions, and suddenly you’ve Think about what happens in a traditional uniform room. People line up, someone checks uniforms in and out, updates records, answers questions, and suddenly you’ve got a bottleneck at the start and end of every shift. With RFID, you can design the process around how your operation works. In some facilities, employees can simply badge in, pick up the garments they need, and go. The system automatically knows who took what and updates the inventory records in the background. No paperwork, no manual tracking, and potentially no attendant standing there managing every transaction. That’s what makes RFID so powerful in large uniform operations. You’re not just tracking garments. You’re removing friction from the process. Employees get through faster, you eliminate choke points, and you still maintain visibility into what’s with employees, what’s available, and what’s sitting at the laundry. The nice thing is that there’s no one-size-fits-all approach. The workflow can be tailored to your facility, your staffing model, and your operational goals. The end result is usually a much smoother process with better inventory accuracy and a lot less manual effort. ... continue reading

We’re constantly short of certain sizes even though we seem to have plenty of uniforms overall. Can RFID actually help with that?

Answer: That’s actually a pretty common situation, and it’s often a visibility problem more than an inventory problem. When someone says they’re short on uniforms, my That’s actually a pretty common situation, and it’s often a visibility problem more than an inventory problem. When someone says they’re short on uniforms, my first question is usually, “Short on what, exactly?” Because having 5,000 uniforms doesn’t help much if the sizes people actually need are sitting in the laundry, assigned to employees who aren’t using them, or overstocked in another part of the operation. What RFID gives you is a much clearer picture of what’s available, where it is, and how it’s being used. Instead of looking at one big inventory number, you can start seeing inventory by garment type, size, location, and status. That changes the conversation from “We need to buy more uniforms” to “Do we actually have a shortage, or do we have the wrong mix in the wrong places?” I’ve seen cases where organizations were preparing to purchase more stock, only to discover they had plenty of inventory overall. The real issue was a mismatch between demand and visibility. RFID helps you see that much earlier, which leads to better purchasing decisions and fewer surprises for employees trying to find the right size. ... continue reading
