Active RFIDs Vs Passive RFIDs
It was probably the irritable nature of
aligning readers with barcodes repeatedly, only to fail the line of sight -that
made way for the rise of RFIDs. RFID tagging system functions on
electromagnetic signals that make it far superior to all of its competing devices.
The RFID asset tracking system in India is
particularly popular because of its ability to transmit across many dense
metals and liquids. This is a rare trait among many signals. Additionally RFID
tracks can be identified by its reader from quite a distance, which is a huge
upside for industries with high security concerns. With these benefits and many
more, RFID tags are a worthy inclusion to many industries.
Active RFID tags suppliers
fit the active labels with their own batteries. These ever-charged
batteries result in the active nature of the tags. These tags are further
divided into beacons and transponders. The beacons, as their name suggests, are
like active beacons continue to transmit signals every few seconds. The
transponders on the other, communicate only when probed by a compatible reader.
The active tags generally transmit on only two frequencies, 433MHz and 915MHz.
Passive RFIDs do not have their own batteries.
Hence, for passive RFID tags, passive RFID readers in India
are a must. These RFID readers, when sending the signal of enquiry, also
provides the label with power that proves just enough for a one-time response.
Otherwise, passive readers are classified according to their transmission
frequency ranges. That can be anywhere between 125 KHz to 960MHz -low frequency
to ultra-high frequency.
