Dear Troy Liu,
Hope you are doing great, I have translated your question, ( google translate)
:"Customers want to know how many levels of UID the PN5180 can support? 4 bytes, 8 bytes, 10 bytes?" to
answer your question: NXP Readers IC’s with NxpNfcRdLib are capable of performing collision resolution of
single/double/triple UID sizes of TypeA technology.
please check the next application note for more information
