The surface looks different on the RFID cards, pvc card and metal card. The two materials are all useful, according to the application you want.
For example, pvc card often owns the lower price and wider application, such as member card, payment card, gift card, etc. However, for metal card, we always look at it as name card, because it looks more noble and durable. So we can use different material in different occasions.
Besides, we can provide different chip in the card, LF(125khz), HF(13.56mhz) and UHF(860-960mhz). What is more, in the size, artwork, color, we can give you the custom design.
