European RFID survey
RFID in Europe AISBL is a not-for-profit organization established in 2012. RFID in Europe's principle goal is to promote the adoption of Radio Frequency Identification and related technology solutions enabling small and medium sized organizations throughout Europe to gain competitive advantage through their best use. RFID in Europe connects with European end-users, operators, solution providers, universities, research establishments, non-government and government organizations and all other European stakeholders through own initiatives and promotion of national projects via our international network. RFID in Europe is an extension of a European Commission FP7 Thematic Network called RACE networkRFID initiated in 2009.
Active RFID is characterised by tags that contain their own power source or battery. With the availability of additional power active tags can support a range of functions that extend and complement those of passive devices. The primary disadvantage of active devices is the finite lifetime of the power source.
Typically this can be a year or so depending upon the battery that is used, the functions to be supported and the power management within the tag. Some types of tag are battery assisted, in that the tag circuit functionality is maintained by battery but when interrogated the tag extracts energy from the interrogation source in order to effect a response.
A variety of active tags are available that exploit different types of battery, the choice being typically determined by the lifetime requirement for the tag and the physical form or form factor required for the tag. The majority of active tags available today use proprietary alkaline or lithium cells. Some tags have re-chargeable cells. The type of power source is of course reflected in the cost, the higher capacity and re-chargeable cells being more expensive. However, the advent of slim, lower cost batteries are favouring the realisation of lower cost active tags.
