NFC

The **ACS ACR1552U NFC USB-C Reader** supports a wide range of NFC cards and tags adhering to specific standards. To ensure compatibility, consider the following specifications and card types when choosing an NFC card:

### Supported NFC Standards:
1. **ISO 14443 (Type A and B)** - Commonly used for contactless cards such as MIFARE cards.
2. **ISO 18092 (NFC Peer-to-Peer)** - Compatible with NFC Forum–compliant devices and tags.
3. **FeliCa** - Used in regions like Japan for transport and payment systems.

2. **NTAG Series (NTAG213/215/216)**:
   - NFC Forum Type 2 tags with wide compatibility.
   - Ideal for smart posters, business cards, and basic identification.

3. **FeliCa Cards**:
   - For applications requiring FeliCa compatibility (e.g., in Japan).

4. **DESFire EV1/EV2**:
   - Advanced security features for payment and secure access applications.

5. **Java Cards (ISO 7816 and ISO 14443)**:
   - Programmable cards for specific applications requiring cryptographic operations.

### Key Factors to Consider:
1. **Capacity**: Choose a card with sufficient memory for your application.
   - **Small (e.g., NTAG213)**: Simple data storage, around 144 bytes.
   - **Large (e.g., MIFARE DESFire)**: Up to several kilobytes for secure applications.
2. **Security Features**: For sensitive use cases, opt for cards like MIFARE DESFire or Java Cards.
3. **Frequency**: Ensure it operates at 13.56 MHz (standard for NFC).
4. **Environment**: Durable or waterproof cards for outdoor/industrial environments.

### Suppliers:
You can find compatible NFC cards from brands such as:
- **NXP Semiconductors**: MIFARE and NTAG series.
- **Sony**: FeliCa cards.
