RFID Card Inlays — LF, HF & UHF
RFID card inlays combine an antenna and chip before final card finishing. Compare LF, HF, UHF, multi-chip and dual-interface constructions by electronics and supply stage; sheet layout is a separate manufacturing choice.

Application & selection
Before choosing this product
Inlay, prelam or finished card?
An inlay is the electronic antenna-and-chip assembly. Prelam adds laminated sheet structure for further processing. A printed finished card includes outer layers, final thickness and personalization. Quote the stage your production line actually needs.
One IC with two interfaces versus two ICs
Dual-interface CPU cards connect contact and contactless interfaces to a compatible module. A dual-frequency or combi construction contains separate electronic circuits. These architectures should not be substituted based only on a similar-looking sheet.
