Active RFID versus passive RFID | RFID4U

Requires presence of interrogator to work

Limited amount data storage

Require higher power interrogators

Low read range (few inches to 20 feet)

Note: A low read range might be considered an advantage or a disadvantage, depending on a tag's application. When a tag is used for credit card or for access control card, a low read range is an advantage, because you do not want somebody to be able to...

Active tag: An RFID tag that has a transmitter to send back information, rather than reflecting back a signal from the reader, as a passive tag does. Most active tags use a battery to transmit a signal to a reader. However, some tags can gather energy from other sources. Active tags can be read from 300 feet (100 meters)...

A CMOS Pressure Sensor Tag Chip for Passive Wireless ...

This paper presents a novel monolithic pressure sensor tag for passive wireless applications. The proposed pressure sensor tag is based on an ultra-high frequency RFID system. The pressure sensor element is implemented in the 0.18 µm CMOS process and the membrane gap is formed by sacrificial layer release, resulting in a sensitivity of 1.2 fF/kPa within the range from 0 to 600 kPa. A three-stage...

1. Introduction

Inductive coupled RFID systems are being used in a huge number of applications such as payment (credit cards), ticketing (public transport and events), access control (company card) and identity verification (ePass, eID). Inductive coupled RFID systems operated in the 13.56 MHz band and are primarily covered by the ISO/IEC standards 14443, 15693, 18000-3 and 18092. The...

Table 1. Comparison of the Typical RFID Read Range According to Frequency Band (Passive Tags)

While Table 1 compares the read range of passive tags, note that there are actually three RFID tag types: active, passive, and semiactive. Because active and semiactive tags use an onboard power source to power the tag response, they are typically capable of much longer read ranges. Passive tags, on...
