Top Wood RFID Catalog
Built the RFID system behind Top Wood's LTOP Interactive Catalog. A custom ESP8266 + RC522 board reads product cards and talks to the catalog over the local Wi-Fi network, so tapping a card opens that product straight away. The board serves its own setup portal for reading, writing and verifying cards and for Wi-Fi setup, and ships with a one-click Windows installer.
