RFID Scanners

What are they?

An RFID Scanner can be used in many different ways.

To recognise a credit card (swipe and go)

Locate products around the world

Used to set off alarms in stores to prevent robbery

An RFID Scanner is a device used to interrogate an RFID tag.

The tags antenna picks up signals from an RFID Scanner and then returns the signal, usually with additional data (like info on the product and the unique number to the tag).

There are however privacy issues with these as RFID tags are now so small that people don't realise if they are still in the product.

Naturally, people are worried about personal information being used against them, i.e. where they live.

The scanners can work for up to 30 meters away from the tag.

Many companies are still tracking their products to this date.

Lets just hope it sticks to being used just in shops and credit cards for now.
