HI There
I'm very interested in your project due to my experience in NFC, Mobile App Development.
I have expertise in NFC Read/Write by NDEF, NFC-A, peer-to-peer mode and I'm very flexible for any kinds of Card such as Mifare Desifre, Ultralight 1k/4k (those are RFID).
Also, I'm very familiar with Zebra SDK and Readers.
For your project we can write book unique ID from you store db into UHF(Ultra high frequency) RFID chipe or tag.
Then you can find specific book from box easily using reader.
Base on my experience, I'm very confident I can deliver your project on time.
Looking forward to hearing from you.
Best Regards.
