    {
      "question": "Is a Java Card the same as a MIFARE DESFire card?",
      "answer": "No. DESFire is a fixed-function chip: excellent at its one job (secure access/authentication), with its memory layout fixed by NXP. A Java Card hosts multiple applets behind a card OS with firewall isolation - different architecture, higher cost tier. If one system does everything you need, DESFire is usually the better buy; if one card must serve several systems securely, that is the Java Card use case."
    },
    {
      "question": "Can Proud Tek load our applets at the factory?",
      "answer": "Yes, under NDA: applet loading and key injection are handled inside your trusted issuance chain - either your integrator loads applets on blank-personalized cards we ship, or we execute the loading script you provide with keys exchanged through your secure channel. Batch traceability and verification reports ship with every order."
    },
    {
      "question": "What is the MOQ and lead time for Java Cards?",
      "answer": "500 pieces per chip type as with our other smart cards, with written quotes and lead times held before tooling. Platform availability varies by generation - confirmed against current silicon stock before we quote."
    },
    {
      "question": "Do Java Cards work in our existing readers?",
      "answer": "On the contactless side, JCOP-family cards present ISO/IEC 14443 Type A or B - but the applet defines what the reader can actually do, so compatibility depends on your application layer, not just the air interface. Send us your reader platform and applet plan and we will confirm before you order."
