The quality of these boards are extremely different. Please notice that there are many sellers (ebay, aliexpress. You can still commit typo, documentation or bug fixes.

For these reasons the library is in freeze mode. Committing changes might break those old projects and lead to bad experiences (for beginners) and support requests.

The development by owner miguelbalboa has ended.įeature status: complete freeze no function or API change.Ĭode status: partial freeze just fixes/typos or documentation updates no extensions for other boards no new examples.

On your Arduino using a RC522 based reader connected via the Serial Peripheralįor advanced and further development please use library RFID_MFRC522v2. Read and write different types of Radio-Frequency IDentification (RFID) cards Arduino library for MFRC522 and other RFID RC522 based modules.
