1 Introduction
1.1 Applicable products
TM801 – an ID tag with limited I/O and memory TM802 – an I/O tag with 256 kbit additional memory, several I/Os and real time clock TM803 – a sensor tag with 256 kbit additional memory, several I/Os, real time clock and a 3-
axes motion sensor
All tags based on these platforms have the same radio circuit:
TM800 – a tag radio module working in the 2.4 GHz ISM band.
The characteristics of the TM800 tag radio module are described in section 2 of this document. The tag platforms are the basis for the characteristics of the various Tag products in the RFIDS™
family, but they vary in form-factors, sensors, user-interfaces, battery types and actuators. For instance the TM801-200 Samui is an ID tag in small form-factor with flanges and without any additional sensor, while the TM802-CLZ Edam has calendar function, LED indicator and a buzzer in a card shaped enclosure. Tag specific product information is given in section 3 of this document.
1.2 Introducing RFIDS™
Active RFID technology has the ability to cater for a broad range of needs in the areas of managing assets, environment and people. These may include:
Ensuring assets are not damaged or stolen Knowing location and status of asset

Ensuring people and assets are where they are expected to be Ensuring people are authorised to be where they are Ensuring people are safe and secure Ensuring environment of people and assets is effective, comfortable and economical
For these reasons, active RFID is not only expected to perform traditional RFID tasks, but can also be utilised as cost-effective wireless sensor networks and provide important functions as contributors to applications in the Internet of Things.
For this reason, TagMaster has named its active RFID technology ‘RFIDS™’, which stands for ‘Radio
Frequency Identification & Sensing’.
TagMaster’s RFIDS™ product line is an active RFID technology designed to meet a broad scope of
requirements. Apart from identification, this may include tracking of movements, status verification, data retrieval, positioning, security alert, sensing, data collection, sensor logging, sensor alerts and actuation of events. Such requirements often demand reliable operation in tough environments at a variety of ranges, typically 3 to 150 metres, and uncontrollable orientations. They may also include requirement tags to perform useful tasks autonomously and independent of a reader.
To meet such broad scope of requirements, while maintaining very good cost-effectiveness and optimal power prudence in all cases, the RFIDS is scalable from an ID tag to advanced sensor and actuation tag. In all variants of RFIDS™, the radio module is the same. The design has built-in expandability with sensor and actuation interfaces, additional memory, security, user-interface, and high accuracy calendar functions.
RFIDS™ makes use of TagMaster’s Fast RFID Air Protocol (FRAP), which can adjust its payload, i.e.
the useful information transmitted from tag to reader and from reader to tag, according to type of tag and/or on a needs basis. For instance, a simple ID tag will indicate to the reader that it is a simple ID tag and only include in its payload what is absolutely needed at that particular point in time. This is important order to minimise duty cycle and thereby improve both anti-collision and battery life. An advanced sensor-tag, on the other hand, might at times require an extended payload to communicate sensor values, alerts, performed actuations and tag status.
In the RFIDS™ system, the FRAP allow all types of RFIDS™ tags to co-exist and be read by the same readers without any confusion. The reader or application does not need to keep long lists of tags for sorting and filtering purposes. Instead, each tag will tell the reader what type of tag it is and what its payload contains.
1.3 Operating principles of RFIDS™
Information from the RFIDS™ tag is sent in ultra-short bursts, whose packets are merely 32 bytes long.
Figure 2 – Information packets sent from tag
Of the 32 bytes, 8 bytes contain security information and a checksum, 5 bytes contain the TID, 1 byte is a payload selector and 18 bytes contain the actual payload.
