Apple Wallet uses NFC, which is a subset of HF (high-frequency) RFID, not LF or UHF RFID. Here's the breakdown:
1. Apple Wallet and NFC
NFC (Near Field Communication) operates at 13.56 MHz, which is the HF RFID frequency.
Apple Wallet allows your iPhone or Apple Watch to act like an NFC key card, transit pass, or payment card.
Communication is short-range (usually 2–10 cm), requiring the device to be very close to the reader.
2. What Apple Wallet Can Do
Digital access cards: offices, gyms, hotels
Payment cards: Apple Pay
Transit passes: metro, buses, trains
Event tickets: concerts, sports, boarding passes
All of these use secure NFC communication with encryption (AES) and tokenization, so the data cannot be cloned like a simple UID-based RFID card.
3. How It Differs from General RFID
| Feature | Apple Wallet | Typical RFID |
|---|---|---|
| Frequency | 13.56 MHz HF | LF: 125 kHz, HF: 13.56 MHz, UHF: 860–960 MHz |
| Security | Encrypted, tokenized | UID-only (LF) or optional encryption (HF/UHF) |
| Phone compatibility | Built-in | Usually requires a physical card or fob |
| Range | 2–10 cm | LF/HF: 1–10 cm, UHF: 1–5 m |
✅ Bottom line: Apple Wallet is NFC-based, meaning it's compatible with HF RFID systems that support NFC or mobile credentials. It cannot emulate LF or UHF RFID cards.
