HexaSwap: The Ultimate Solution for NFC ID Compatibility and Endianness
Avoid NFC card reading frustrations. HexaSwap scans, converts, and performs endianness swaps (Little-endian to Big-endian) on NFC card IDs or tags, ensuring compatibility with different systems and readers. Digitize or scan your card and get the correct format instantly!

Are you having trouble reading NFC cards due to different byte orders? Many electronic devices interpret NFC card data differently (big-endian or little-endian), leading to incompatibilities and errors when trying to use a card with multiple readers. HexaSwap is designed to eliminate this frustration.

What is Endianness and how does HexaSwap help? "Endianness" refers to how data larger than one byte is stored in memory. Some machines read bytes from left to right (big-endian), while others read them from right to left (little-endian). HexaSwap offers a practical solution: it performs an endianness swap to adapt your NFC card ID to the format you need.

HexaSwap's main features:
• Fast and Reliable NFC Scanning: Simply bring your device close to an NFC card or tag, and HexaSwap will instantly read its unique identifier.

• Flexible ID Entry: Manually enter your card number or scan it directly with NFC.

• Automatic Endianness Swap: Converts your card or tag's decimal ID to hexadecimal, performs the endianness swap, and delivers the new hexadecimal value ready to use.

• Intuitive Interface: Receive clear notifications about the NFC status and the scanning process.

How does it work? When you open HexaSwap, the app checks your NFC status. You can scan an NFC tag, whose ID is automatically populated in the input field, or enter it manually. Once entered, the application processes the number, performs the endianness swap, and displays the result in the desired format.

Note: HexaSwap includes ads to support ongoing development and offer this tool for free.
