For any RFID-based project,  first a TAG will be chosen – i.e. the technology underlying it (NFC-UHF) – and then a type of material will be selected; this will contain the tag or will be coupled to it, possible applications and uses will grow as a result.

As there are several applications and types of material, you are kindly requested to contact us with the details of your application so that our technical staff and engineers can advice you on the best technology to be applied to that specific use.

Here is some general information on RFID technology

Compared to traditional barcode technologies, RFID technology offers some basic advantages:

  • No need to be visible to be read
  • Information can be added in the chips, based on their type.
  • Identification and check occur in one tenth of a second
  • Multiple TAG reading in a second
  • Communication can be uncoded or coded

 

 

NFC Technology

NFC stands for Near Field Communication and refers to a short-range RFID communication technology using 13.56 MHz frequency waves, which allows for two-way communication with two devices.

It is applied following various standards such as ISO 14443 A/B and Mifare.

Communication is two ways and data exchange maximum speed is 424Kbit/s.

Some example applications are: contactless payment, electronic ticketing, asset management, attendance detection and many more currently underway.

NFC technology related features:

  • Two-way communication between devices
  • Peer-to-peer communication (please note: this technology cannot read more RFID tags simultaneously)
  • Reading distance within a few centimetres
  • RFID tags are 20mm to 40mm wide in diameter.
  • NFC RFID tags have rewritable memory capacity from 48 Bytes or 32 Kbytes and higher
  • For applications on metal, special tags (metal-mount) are recommended
  • NFC tags are more expensive than UHF tags
  • NFC readers/writers can be smart phone integrated
  • Labels carrying NFC tags can be printed or etched using printers with special features

 

UHF technology

Within RFID, UHF (Ultra High Frequencies) range from 865 MHz to 960 MHz, which is definitely higher than the range adopted within NFC technology: higher frequencies mean faster transmission.

This is applied following various standards such as ISO18000-6C, ETSI EN 330 220, etc.

Communication is two ways and speed – proportional to frequency – higher than HF communication as a result.

UHF technology has been used since World War Two in the military field; however it was only in the 2000s that it was able to benefit from standards which have allowed for its wider use in the industry, in logistics, distribution, warranties and anti-counterfeiting.

UHF technology related features:

  • point to multi point point to multi pointPoint-to-multipoint, two-way communication between
  • Capable of simultaneous reading of multiple tags per second and multiples of 100, e.g. 400 tag/s
  • Reading distance up to 2m for handheld scanners and up to 10m for presentation scanners
  • Size ranges from 5mm to 10cm for any application type
  • UHF RFID tags’ rewritable memory ranges from 96 bit to 2k bit and above
  • For applications on metal, special tags (metal-mount) are recommended
  • UHF tags are more economical than .2167 +8NFC tags
  • UHF readers/writers can be integrated into industrial handheld PC or equipped with Bluetooth to be connected to any PC or smart phone
  • Labels carrying UHF tags can be printed or written using printers with special features
