NFC Emulate: Card Wallet 앱 분석 (11월 11일)

NFC Emulate is an NFC reader, NFC card emulator and card wallet for Android. Scan NFC cards and tags, save them, and emulate them from your phone. No cloud, no account, no sign-up. ⚠️ PLEASE READ BEFORE INSTALLING • Most door, gym, office and parking readers check the card's UID (its serial number). Copying the REAL UID needs a ROOTED phone with a compatible NFC chip. • Without root, Android always sends a RANDOM UID when emulating, so UID-checking readers will refuse it. This is an Android rule, not a bug in the app. • Encrypted cards (MIFARE Classic, MIFARE DESFire, bank and payment cards, ID cards) cannot be copied by any phone. • Many apartment and gym key fobs are 125 kHz RFID, not NFC. Phones cannot read 125 kHz fobs. The app tells you, for every card you scan, whether it can be emulated on your phone. 🔍 NFC CARD AND TAG READER • Read the UID, ATQA, SAK and technology type of NFC cards and tags • See full card details instantly with one tap • Works with MIFARE Ultralight, NTAG, ISO 14443-A, ISO-DEP and other NFC standards • Detects encrypted cards and explains why 💾 CARD WALLET: SAVE AND ORGANIZE • Save your cards with custom names • Colour-code each card with a hue slider • Drag and drop to reorder • Your most-used cards rise to the top automatically 📲 NFC CARD EMULATION (HCE) • Emulate saved cards with Android Host Card Emulation (HCE) • Works with readers that talk to the card using APDU commands • Open a card quickly with a shake gesture 🔓 ROOT MODE: REAL UID EMULATION • On a rooted phone, NFC Emulate writes the card's real UID, ATQA and SAK to the phone's NFC controller • Your phone can then present the original card identity to UID-based access readers • Proven on phones with NXP NFC chips.

See our privacy policy for details ❓ HOW IT WORKS, AND WHY A READER MAY SAY NO Every NFC card has a UID, like a serial number. Simple readers only check that number. When a phone emulates a card, Android picks a NEW random UID each time for privacy, and no app is allowed to change it. That is why a reader that checks the UID rejects a phone without root. Root lets NFC Emulate write the real UID into the NFC chip itself. Encrypted cards keep a secret key inside the card chip. That key can never be read out, so no phone and no app can copy them. The card screen in the app tells you which case applies before you try. 💬 HELP Not sure if your card or phone is supported?
