Semi-active RFID Tag

Semi-active RFID tags are the middle ground between passive and active tags, offering a blend of benefits. Like passive tags, they don’t have the continuous broadcasting power of an active tag. However, they do contain a small, long-lasting battery. This battery doesn’t power constant transmission, but rather boosts the signal when activated by an RFID reader. This extra oomph allows for a longer read range compared to passive tags, making them suitable for applications where items might be further away or require some additional data transmission. They also boast a bit more memory than passive tags, allowing for sensor integration in some cases. While not quite as powerful as active tags, semi-active tags offer a good compromise between read range, functionality, and cost, making them ideal for tracking assets within warehouses or monitoring environmental conditions of products in transit.

Some of the features of semi-active RFID tags are:

They have a longer read range than passive RFID tags, but shorter than active RFID tags.
They can store more data and perform more complex operations than passive RFID tags, but less than active RFID tags.
They can monitor and report environmental conditions, such as temperature, humidity, or shock.
They have a shorter lifespan than passive RFID tags, but longer than active RFID tags.

Active RFID Tag

Active RFID tags are the go-getters of the tag world. Unlike their passive counterparts, they don’t rely on borrowed power. Instead, they pack their own punch with a built-in battery. This lets them broadcast a signal continuously, acting like a beacon in the radio wave world. With a much stronger signal and longer read range, active tags are ideal for real-time tracking of valuable assets or items on the move, like shipments or even high-end inventory in stores. While they cost more due to the battery, active tags offer unbeatable performance for keeping a close eye on your important things.

Some key features of active RFID tags include:

They’re battery-powered tags that continuously transmit signals
They are commonly used to transmit data in real-time
Each one has a signal range of up to 150 meters

Passive RFID Tag

Forget batteries! Passive RFID tags are tiny hitchhikers that power themselves. Unlike their active cousins, these tags have no internal battery. Instead, they cleverly snag the energy from an RFID reader’s radio waves. This borrowed power activates the chip inside the tag, allowing it to transmit its stored information back to the reader. Think of them as mini wireless passports for your stuff!

Some of the features of passive RFID tags are:

They do not have a battery or power source of their own. They rely on the energy supplied by the RFID reader to operate.
They have an antenna that captures the RF signal from the reader and a chip that stores and processes data.
They can be very small and discreet, often embedded within product labels or objects.
They have a long lifespan, as they do not need battery replacements.
They can store information such as unique identifiers, product details, or other relevant data. Some tags also have rewritable memory.
