RFID Stickers, labels, and inlays are all commonly used for inventory tracking, supply chain management, and asset tracking. RFID stickers and labels are meant to be attached to objects or surfaces, while RFID inlays are designed to be embedded within an object or material.
An RFID label features a printable face stock material on top of an inlay. An RFID sticker will see an adhesive base added to a label. They are usually made of paper or plastic.
On-metal RFID stickers are specifically designed to perform on metal surfaces by adding a spacer that creates a gap to shield the RF antenna from the metal. Most on-metal labels, in turn, perform poorly on non-metal surfaces such as plastics.
As a guideline, a label oriented horizontally would achieve 50% of its reference read-range performance with a minimum bending radius of 40mm (1.6in). Oriented vertically, the minimum bending radius would be 25mm (1in).

Doped Mott insulators are the starting point for interesting physics such as high temperature superconductivity and quantum spin liquids. For multi-band Mott insulators, orbital selective ground states have been envisioned. However, orbital selective metals and Mott insulators have been difficult to realize experimentally. Here we demonstrate by photoemission spectroscopy how Ca2RuO4, upon alkali-metal surface doping, develops a single-band metal skin. Our dynamical mean field theory calculations reveal that homogeneous electron doping of Ca2RuO4 results in a multi-band metal. All together, our results provide evidence for an orbital-selective Mott insulator breakdown, which is unachievable via simple electron doping. Supported by a cluster model and cluster perturbation theory calculations, we demonstrate a type of skin metal-insulator transition induced by surface dopants that orbital-selectively hybridize with the bulk Mott state and in turn produce coherent in-gap states.
a Valence-band energy distribution curves (EDCs) versus energy relative to EF plotted in the order of Rb deposition levels. Spectra are given arbitrary vertical offsets for a visibility purpose. The inset indicates the momentum window for integration. b Valence band EDCs aligned to the O 2p peak position and normalized to the total intensity in the displayed energy region. c Spectral weight of the lower Hubbard band (LHB) and the near-EF part integrated within the magenta and green shaded regions, respectively, in (b). The LHB spectral weight is estimated after subtracting a tangential linear background shown by dotted lines in (b). The weight has been normalized to the maximum values. d The position of LHB with respect to the O 2p peak position plotted as a function of the Rb deposition sequence. The error bar is determined from intensity variation around the peak surpassing the noise level.
Our main observation is a metallization of Ca2RuO4 upon application of alkali-metal atoms. A central question is whether this quantum well state is a hybrid state between alkali metals and Ca2RuO4. We address this question by inspecting: (i) the spectral weight of the LHB, (ii) the Ru-core levels, and (iii) the self-energy effects of the induced quantum well state.
(i) Mono-, bi-, and tri-layer alkali-metal deposition have been reported9,26 on Sr2IrO4 and Sr2RuO4. Due to the large inelastic mean free path of alkali metals27, bulk bands are observed through the alkali-metal layers in both cases. The observation of drastic LHB suppression (Fig. 3) is thus intrinsic and not an artifact of an alkali-metal overlayer. With few exceptions28, spectral weight suppression of the Hubbard bands is associated with quasi-particle formation near the chemical potential16,29. This is consistent with our observation of a fading Hubbard band being replaced by a valence band as a function of alkali-metal dosing.
(iii) Finally, the kink witnessed both in the band dispersion [Fig. 5f] and MDC linewidth [Fig. 5g] of the metallic band suggests strong self-energy effects. The energy scale of 0.4 eV is incompatible with electron-phonon interactions and rather points to electron-electron interactions. In fact, such high-energy kinks have been widely observed in strongly correlated systems like cuprates33,34 and ruthenates35, and interpreted as a manifestation of many-body self-energy effects. The kink, therefore, suggests substantial electron correlations induced by substrate Ru orbitals. Such correlation effects are not expected (or reported) for a purely alkali-metal quantum-well states11.
The analysis has been performed for a representative case for the set of parameters used for the single site cluster calculation. Small variations do not affect the qualitative character of the Fermi pocket. The overall outcome is compatible with our experimental observation. We conclude that this scenario provides a novel type of surface Mott-insulator to metal transition realized through chemical doping. Note that a metallic in-gap state can also emerge by directly injecting carriers to the Hubbard bands16,48. However, the present single-band in-gap state is incompatible with such direct carrier doping and instead suggests the orbital-selective formation of covalent bonds.

Background: In the world I'm building, "magic" is a technology that uses different wiring patterns to manipulate electromagnetic, and a some levels quantum, properties. People have these patterns placed on their bodies in what is essentially a metal tattoo in order to gain these powers, but for illegal/black market marks, they are essentially pouring ribbons of molten metal directly onto the skin.
Just recently scientists figured out how to print circuits directly onto the skin source. The are printing silver directly on to the skin with no barrier layer in between, by using a secondary compound that allows the silver to sinter at room temprature.
There are only two molten metals (elemental) that would not instantly deep fry (or deep freeze) a person's skin: gallium and mercury. As you can see in this video (get up to about 6:15), mercury doesn't wet the skin -- it won't stick. And as you can see in this video, the same holds true for gallium. Don't worry about mercury poisoning! Elemental Hg is relatively safe and it takes quite a while for enough to absorb to be dangerous. Ga is non toxic.
As for metal tattoos, that's really not a good idea at all. Injecting oneself with mercury ranks up there withe the best of the Darwin Award winners. In fact, IV injection of Hg is one means of attempted suicide. It's also used in Ayurvedic medicine.
The body can indeed work well with some implanted metals, notably titanium, which is used in fixing fractures. Mercury won't work so well, not only because it will eventually become toxic, but also because it won't form a "tattoo". What will happen is there will eventually form an abscess full of mercury and you'll also have lots of time droplets of mercury spread all along the injection track.
But you're looking at a magical system here, and therein lies the difference. There are metals, bismuth alloys in particular, that have melting points that would be (just barely) tolerable for a biological system, BEND metal, for example. It melts at a little less that 160 degrees -- enough to burn, but if managed should pose no lasting harm.
What they'll need is a kind of biothaumic flux, kind of like how ordinary flux is applied to a surface in order to get solder to bond to it, so biothaumic flux is applied to the skin in order to a) protect it somewhat from the heat of the metal and also b) to help the metal adhere to the skin.
The application of such thaumic tattoos is technically simple, but requires much study & practice by the tattooist in order to get the patterns to go right. Visually, it's not a whole lot different from henna application.
There are other answers covering other approaches like tatoos and silver painting, etc, but one approach which hasn't been mentioned is that molten plastic will bond to skin, and metals can be mixed with plastic.
I've had the unfortunate experience of receiving what's known as a "Tar burn", which is when some molten plastic merges to skin. Typically this happens when synthetic clothing melts onto the skin (in my case, nylon handles on a fire dancing item got tangled with the hot end, I separated the two with a kick, but neglected to wait before I picked up the molten handles).
Molten plastic will still be merged with the skin until the skin dies and is shedded, if the burn was a nasty burn, the skin will be shredded within a few days, however a very mild burn that doesn't peel and it could stay bonded for months. (First aid guides I've read advise not pulling molten plastic off - cool it ASAP, and then wait for the plastic to come off on it's own).
