CHOOSING THE RIGHT RFID
Choosing the right RFID can be difficult. How should you choose?
Making the right choices can be challenging. With so many technologies, standards and formats, the range of options open to users is very wide indeed. You need to consider certain factors when choosing the right RFID technology for you and your business. CoreRFID offers a full range and can help you with advice.
Here are some of the questions that you’ll need to ask in order to help you choose:
Thinking about the application of RFID
- Is passive RFID the answer or are active tags needed?
- Does the solution need a hybrid RFID/barcode approach?
- Does the reader go to the tag or the tag to the reader?
- How close can the tag be to the reader?
Thinking about RFID readers
- What frequency tags will you need to read? (HF/LF/UHF)
- What type should it be? (fixed location; plugged into PC, lap-top or PDA; integrated in PDA; stand-alone)
- For stand-alone readers, how many tag id’s must it store?
- How will it communicate? (wifi, Ethernet, Bluetooth, serial)
- How will it plug in? (USB, Ethernet, WiFi). How important is read range/sensitivity?
- What are the anti-collision needs (reading many tags at once)?
- Do you need to be able to write tags as well as to read them?
Thinking about RFID Tags
- What are you attaching them to? (plastics, wood, metal)
- How can you attach the tag? (stick on, strap on, rivet/screw, mould in)
- Is there a size limit for the tag? (bigger tags generally have better read range)
- Does it need to survive a specific temperature/humidity range?
- Does it need to survive chemical immersion/dust/magnetic flux?
- Does it need to be rugged?
- Do you need personalisation (logo/printing)?
- Do you need to both read & write and why?
- Do they need to match existing tags?
- How far away do they need to be read from?
Thinking about PDAs for RFID
- Do they need barcode & RFID capability?
- Do they need a camera?
- How will data be retrieved from them?
- Do they need integrated GPS?
- Could you combine with a smartphone/tablet?
