Semi-active RFID Tag

Description

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.
