UHF + Mifare (S50)
Hybrid cards or combo cards are a term applied to cards that contain two or more embedded chip technologies in a card. They offer a unique solution for updating existing badging system.
HF + UHF cards are becoming increasingly popular in loyalty and payment schemes that also want to track attendance and location of a customer. These hybrid cards generally have the UHF chip placed separately above or to the side of the HF chip to ensure there is no interference.
