NFC Reader with STM32

Using an STM32F1 Microcontroller and a NFC reader like PN532 (or any other), write C code to read multiple tags (one by one) and add their UUID to an array. The tags are placed within reading distance of the reader and the reader must read all tags and log their data to an array. No hardware or circuit design is required, only the STM code is required, along with the description of the hardware used (modules or chipsets that are used). Only limitation is that the NFC reader must be economical.
