Today’s post won’t be an exhaustive study of the subject, what follows provides a brief introduction to Near Field Communication (NFC) tags.As designers/builders of new or existing inanimate things we transform into wireless communiction devices by means of integrating NFC onto or into the inanimate thing the first thing we learned when talking with people is to eliminate technical jargon at every opportunity. This is the reason we prefer to refer to NFC tags as electronic stickers. People just seem to get it right away. Technically speaking NFC tags are a type of Integrated Circuit (IC.) When we engage in conversation using technical terms it often generates a blank stare. Don’t we all feel a tad uncomfortable when we’re not really a part of the conversation hecause we don’t understand the gist of the subject matter? Because a picture really can be worth 1,000 words we’ll use a picture of an electronic sticker to illustrate some fundamentals… NFC tags we refer to as electronic stickers are unpowered, often called “passive tags.” When an NFC-enabled SmartPhone is used to make a tapping gesture near or upon the sticker electromagnetic energy is eminated from that powered device, the antenna becomes energized transferring power to the chip which functions as a controller to allow reading, writing and erasing data which can be stored in the memory. By specification, when data is written to the memory the data may be “locked” which makes the data permanently read-only making the use of electronic stickers a 100% secure means to store data. The data payload is not that large, typically at this pint in time the maximum size of a payload is 800 bytes depending on what type of tag is acquired from the semiconductor manufacturers who manufacture different types which comply with official specifications that may be manufactured in round, square or rectangular form factors. Even though the payload is not that large a lot of functionality can be accomplished as the next picture will depict. When a specific data set is written and stored in the memory of the circuit the following tasks can be accomplished: These electronic stickers are a type of Near Field Communication (NFC) Integrated Circuit (IC) referred to as NFC tags to differentiate NFC tags from a similar type of IC known as Radio-Frequency IDentification (RFID) which was invented before NFC. The antenna-chip-memory form-factor as you will see is nearly exactly alike causing confusion. RFID was invented first and they became known as RFID labels. This would be because a Factually, NFC is one of those technologies that is similar but still different than aa sub-set of RFID. Because NFC tags look like RFID labels The acronym RFID refers to a small electronic integrated circuit that consists of a small chip, memory and an antenna. These types of IC became known as RFID labels as the IC is typically covered with a printable label.
