RFID card inlay / Prelam (core material)
Mar 03, 2018

RFID Inlay / prelam

RFID inlay / prelam is composed of an IC (Integrated Circuit, Chip) and a Dipole antenna. 

RFID inlay can be either "wet" or "dry"  

Wet inlays are inlays that have an adhesive backing with a clear or colored topsurface of PVC,PET or paper, the PVC or PET wet inlays are commonly used to make "RFID Labels"  where the inlay is placed on the back of the label with the adhesive side away from the label side so that the label has continuous adhesive.  PLacement of the wet inlay on the label is very specific to each RFID printer in order to be programmed correctly by the printer and also to minimize the risk of damaging the RFID inlay while in the printer.

Dry inlays are inlays that are attached to the substrate backing material commonly called the web. 

Antennas can be made of silver, aluminum or copper, with each material producing very specific read and write characteristics because of the different chemical properties.  While there are some more exotic materials sometimes used for antennas they are considerably more expensive to produce and very vertical application specific. Generally a copper antenna is slightly more expensive that aluminum or silver but is more conductive and usually provides a longer distance read capability.

As core part of RFID card, we provide high-quality RFID inlay which they are suitable to ISO standard cards and made into different thickness and various shape for option. We have advanced ultrasonic technology, and aluminum(AL) etching techniques, so the quality of our products is not only stable also durable and better Reading and writing performance.
