Why are rfid tags more expensive than passive tags?


Asked by Magnus Carson on Dec 12, 2021 FAQ



For more valuable items that need tags which last longer, Active and Semi- passive RFID Tags are used. But they are more expensive than passive tags and hence are used rarely in low-value goods. 1. RFID chips and RFID readers are highly resistant to substances such as water, oil and chemicals. 2.
Just so,
Passive RFID tags tend to be smaller and less expensive than active tags, as they do not require a power source or transmitter. Instead, passive systems use a tag chip and antenna to transmit a radio signal to the RFID system. The passive RFID tag powers on when a radio signal is received, and reflects the signal back to the reader.
Also Know, The active RFID tags will cost approximately $16 each. Total tag cost is $25,600. Let’s assume the customer needs 10 active RFID readers, which will cost about $1,000 per reader, for a total of $10,000 in reader costs. The control software will cost approximately $13,100 including support.
Accordingly,
This explains why passive tags are smaller in size and more expensive than active tags. Once the tag receives the signal, it generates a response and sends it back to the reader on a different frequency level. This response generation process is called backscatter.
Next,
Scalability and functionality are two major criteria that define your choice of RFID tag. You can even choose to have both active and passive RFID technologies work in tandem according to your tracking requirements.
