It is divided into 3 layers: 1. Defines the hardware characteristics of the VICC, 2. Defines the carrier frequency and the bit-level communication scheme, 3. All VICCs are memory chips. Their data storage area is divided into blocks. The size of the blocks and the number of them depend on the VICC.
It is divided into 4 layers: 1. Defines the hardware characteristics of the PICC, 2. Defines the frame-level communication scheme and the session opening sequence anti-collision , 4. The application-level is out of the scope of ISO NFC Near-field communication. A subset of RFID, where the operating distance is much shorter than the wavelength of the radio waves involved.
The proximity and vicinity ranges are shorter than this wavelength. VCD Vicinity coupling device. A device able to communicate with a VICC, i. VICC Vicinity integrated circuit card. This is the standard name for any contactless card compliant with the ISO standards vicinity: less than cm.
PCD Proximity coupling device. A device able to communicate with a PICC, i. PICC Proximity integrated-circuit card. This is the standard name for any contactless card compliant with the ISO standards proximity: less than 10cm. This could either be a smartcard or a memory card, or also any NFC object running in card emulation mode.
Overview[ edit ] Similar ideas in advertising and industrial applications were not generally successful commercially, outpaced by technologies such as barcodes and UHF RFID tags. NFC protocols established a generally supported standard. When one of the connected devices has Internet connectivity, the other can exchange data with online services. NFC-enabled portable devices can be provided with application software , for example, to read electronic tags or make payments when connected to an NFC-compliant apparatus. Earlier close-range communication used technology that was proprietary to the manufacturer for applications such as stock tickets, access control and payment readers.
