The RC522 is a basic RFID reader limited to MIFARE cards and SPI communication only. In contrast, the PN532 supports full NFC protocols (including peer-to-peer and card emulation), works with a wider variety of tags, and offers three interface options (I2C, SPI, HSU), making it the ultimate choice for flexible NFC module Arduino projects.\u003c\/span\u003e\u003c\/p\u003e","brand":"Robocraze","offers":[{"title":"Default Title","offer_id":40193169096857,"sku":"TIFCC0045","price":269.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0559\/1970\/6265\/files\/Products_82_7adcfa0c-1ad2-4b96-ba44-a20e7d5a8733.png?v=1752210648","url":"https:\/\/robocraze.com\/products\/pn532-nfc-near-field-communication-rf-id-v3-module","provider":"Robocraze","version":"1.0","type":"link"}
