  "faq": [
    {
      "question": "How quickly can we migrate from legacy cards to encrypted ones?",
      "answer": "A phased migration can begin within 2-4 weeks. Proud Tek can deliver custom-printed MIFARE DESFire EV3 cards within 7-10 business days. The total migration timeline depends on the number of access points, reader compatibility, and organizational logistics for distributing new cards to all users. Most facilities complete a full migration within 3-6 months."
    },
    {
      "question": "Is it worth upgrading if we have not detected a cloning incident yet?",
      "answer": "Yes. The absence of a detected incident does not mean one has not occurred. Cloned cards produce access logs identical to legitimate cards, making detection extremely difficult. Upgrading proactively is far less costly and disruptive than responding to a confirmed security breach after the fact."
    },
    {
      "question": "Can we use the same card for access control and other applications?",
      "answer": "Yes. MIFARE DESFire EV3 supports multiple independent applications on a single card. You can partition the chip for building access, elevator control, parking garage access, cashless vending, and print management, each with its own security keys and data partitions."
    },
    {
      "question": "Do we also need to replace the wiring between readers and the access control panel?",
      "answer": "If you are running classic Wiegand between the reader and the panel, the answer is usually yes. The Wiegand protocol transmits the card number in the clear over a short-distance copper run, which means an attacker who can briefly access the cabling can sniff valid credentials regardless of how strong the card encryption is. The modern replacement is OSDP v2 with Secure Channel (AES-128 between reader and panel). Most current HID, Allegion, ASSA ABLOY, dormakaba, and Mercury Security panels and readers support OSDP, but the install requires a firmware check, a wiring change to RS-485, and configuration on the panel side."
    },
    {
      "question": "How do mobile credentials and Apple Wallet keys fit into a post-cloning upgrade?",
      "answer": "Mobile credentials are an additive layer rather than a complete replacement. A modern Apple Wallet or Google Wallet key uses the phone's Secure Element together with biometric unlock, which makes it far harder to copy than a plastic card and lets you revoke a lost credential instantly from the access management portal. They also reduce the number of physical cards you have to recall during a breach response. The trade-off is reader compatibility — most legacy 125 kHz panels need a Bluetooth or NFC-capable reader added (HID Signo, Allegion Schlage MTB11, dormakaba RCI, or Wavelynx Ethos are common choices) before mobile credentials become an option, so plan the reader refresh and the credential migration as one project."
