We usually stock NFC label/stickers as either clear NFC labels or white NFC labels which consist of two layers of very thin plastic with the antenna sandwiched in-between. However, as many of customers are starting to use tags in more and more unique and varied cases, we are starting to now also stock a 29mm tag as both a 29mm NTAG213 wet inlay and an NTAG213 dry inlay variant.
A wet inlay consists of a single layer of plastic with the antenna on one side and the return path on the other. Unlike a standard sticker/label, where there's a second layer of plastic so that the antenna and chip are protected, the chip on a wet inlay is exposed. This single layer means that the tag is very thin which makes it ideal for lamination between cardboard, paper or for application behind an over-sticker. The downside is that they are weaker, so they need to be handled with a little more care. Supplied on a reel with permanent adhesive (on the chip side) with an NTAG213 chip.
Dry inlays are the same single layer of plastic with antenna but have no adhesive and are not die cut. Dry inlays are supplied on a continuous roll of plastic and need to be cut to be used. Also with the NTAG213 chip and with a 25mm diameter antenna.
Dry inlays are very delicate as the NFC chip is exposed on one side and the 'labels' are not cut individually. Care must be taken when cutting these into separate units to be used in your application.
Both these items are now stock and we will continue to hold them and restock them.
There's actually a very wide variety of different constructions including specialist labels that can work on metal surfaces. If you want to read about the different types including reverse wet inlays, on-metal tags, reverse on-metal tags, printed labels and more , then read our guide to NFC label formats.
