+First challenge was the usage of I2C, where it uses 7-bit to 10-bit addresses to make the identification of devices on the bus, with many PN532 address conflict can increase because of the limited number of unique addresses. In addition, data collision and bus contention can increase in an environment with high communication traffic because I2C use the same set of wires (SDA and SCL) to the communication of multiple devices. Switching to SPI was the choice since SPI uses separate Chip select for each PN532 that eliminate address conflict, make device management more easy. Moreover, SPI enable a fast communication between the microcontroller and the PN532 because it has a higher data rate as well as it allows simultaneous data transmission and reception. The usage of SPI facilitate the addition of new PN532 to the system since its only require to identify a specific chip select line for every new PN532.\\
+Second challenge was the electromagnetic interference. When the PN532 where on, they were interfering with each other, causing a disruption in their operation. This interference created a dead spot in the detection area because both boards were not able to read data. Additionally, these interference has weakened the detection range of each board that reduces their efficiency and reliability. This has affected the overall performance of the system, making difficulties to have accurate reading from the devices.

-In this project, the initial use of I2C communication for PN532 NFC/RFID has faced a challenge, the distinguish between multiple boards. The switching for SPI communication has solved the issue by the usage separate cheap select lines that made the communication more reliable and stable. Despite these improvements, the interference between the boards is still a challenge that promotes to explore techniques such as physical separation and shielding. Future work should focus on advanced method to reduce interference, improve system flexibility and real world testing to increase overall performance.

+Future work:\\
+Where to pick up this project?
+The main focus should be on advanced method to reduce electromagnetic interference as this was the main challenge in our project , improve system flexibility where it can track multiple behaviors like chicken nesting habits and health tracking, and real world testing to apply the methods and then accordingly make changes in hardware or software.

-==== PN532 Module V3 by Elechouse (5V, red board) ====
-This is the cheap version (the red board with 8 + 4 pin headers / connectors) you still can buy everywhere. Drawback: Only the 5V is exposed to the connector and not the 3.3V output. The board has to be modified to be usable with a 3.3V voltage source, e.g. by desoldering the voltage regulator and building wire bridge from 3.3V to the power pin on the connector (origially named 5V).

-===== Terminology =====
-Bird ringing is the term used in the UK and in some other parts of Europe and the world. Bird banding is the term used in the US. Organised ringing efforts are called ringing or banding schemes, and the organisations that run them are ringing or banding authorities. (Birds are ringed rather than rung) Those who ring or band are known as ringers or banders, and they are typically active at ringing or banding stations.
