These composite cards combine HID iCLASS Seos and Prox technologies to offer secure 13.56MHz read/write contactless access. With 16k bytes of memory, these cards provide advanced cryptography and privacy protection, ensuring a secure environment. The absence of traceable identifiers during card sessions prevents data from being compromised or cloned. These cards meet ISO standards for card thickness and are made of durable PVC/PET material.HID iCLASS Seos and Prox technologies combined16k bytes of memoryISO standard thickness and durable PVC/PET material
