Is the lack of standards the only thing that has prevented long range RFID from being more widely used?
No. Long range RFID is expensive. One reader set-up typically costs $1,000 or more. Companies would need thousands of readers to cover all their factories, warehouses and stores. RFID tags are also fairly expensive – 20 cents or more – which makes them impractical for identifying millions of items that cost only a few dollars.
