placiibo is a versatile NFC writing tool developed by Shipwreck LLC. This iPhone application lets you write raw binary files to NTAG215 NFC tags, which can be used for various purposes like access management, employee or student IDs, or even to interact with video games that support it. With placiibo, you can import and keep track of your binary files in a library and write them to NFC tags with ease.

The app provides encrypted writing to tags, ensuring the security of your data. placiibo also offers a customizable app icon and a dark mode option. However, it is important to note that placiibo requires a paid subscription to use all the features. The free version of placiibo provides a demo on first-time use and a limited trial to test out.

It is worth mentioning that placiibo does not provide binary files or encryption keys, which must be provided by the user. Additionally, the app currently only supports NTAG215, writing encrypted NFC tags, encryption keys of 160 bytes, and binary files between 532 bytes and 572 bytes. Lastly, placiibo does not support NDEF.

Overall, placiibo is a reliable and efficient NFC writing tool for those who need to write raw binary files to NTAG215 NFC tags.
