NFC tags are tiny microchips that can be embedded into different objects, such as NFC business cards. These tags can be customized with various graphics and can be used in applications that don’t require a smartphone application. Moreover, they don’t require a power source and can stay attached to objects for years.
An NFC tag consists of three basic components: the chip, antenna, and substrate. The chip is a small, low-powered microchip with memory and communication technology. The antenna is usually a thin wire coil. The tag’s substrate, which is usually a thin plastic sheet, holds everything together. The sticker tag itself will have an adhesive on one side.
The most basic NFC tag is called a type 1 tag. It is inexpensive, and can store 93 bytes to two kilobytes of data. While this is still less than a microSD card, it is still adequate for ticketing and access control. Some NFC tags also offer additional features, such as improved interference handling, tamper resistance, which are ideally used for custom NFC tags.
NFC tags are useful for automating home automation. They can be used to control smart devices around the house by holding them near NFC enabled smartphones. Guests can connect to the Wi-Fi network by scanning the NFC tag. Moreover, they can be programmed with any type of data. For example, an NFC-enabled poster can carry a URL, a picture, or a video. The smartphone can then read the information embedded in the poster. NFC stickers can control the phone’s mode. It can be used with writing applications, such as Trigger, to toggle between writing and phone mode.
