RFID Tag - Battery Assisted Passive Tags - CoreRFID

If you need greater read distances or quicker response times than can be achieved with ordinary RFID tags, the answer may be in battery assisted passive tags.

Conventional RFID tags use the power from the readers signal to turn on and then to run the chip, power the memory and power the transmission back to the reader. As a result the distance between the reader and the tag has to be close enough...

RFID tagging System for Asset/Inventory Management

RFID tagging of inventory enables each individual item or component to be allocated unique identification and be uniquely tracked throughout the production and distribution supply chain. RFID readers are placed at various locations within a factory or warehouse and at entry/exit gates. They continuously read tags that are within range and send this data back to the controlling system. Data associated with each unique tag gets easily updated on the server when the tagged items are moved from one location to another. RFID has no line of sight requirements since the tags can be read remotely over a considerable distance. Unlike barcodes,...

What's The Difference Between NFC and RFID?

June 3, 2013

You have probably heard these two terms a lot lately: NFC and RFID. You probably also know that both of these technologies have something to do with wireless scanning, chips, tags and readers - and you are right.

NFC is part of the RFID technology, representing just one of the Radio-frequency identification standarts.

But a lot of people still don't really know (yet) what the difference between NFC and RFID is! Let's look at the definitions of the separate technologies first and then look at how they are different.
