NFC IDEAS Web Reader

NFC Web Reader by NFC IDEAS Read and write NFC tags directly in Google Chrome using any standard USB PC/SC NFC reader — no mobile device or dedicated app required. Works on Windows and Mac. What it does The NFC IDEAS Web Reader extension bridges your USB PC/SC reader to the nfcideas.com web app, enabling you to scan, decode, and write NFC tags from your browser. Place a tag on the reader and the decoded content appears on the page within seconds — or write a URL to a blank tag in just a few clicks. Decodes all standard NDEF record types: • URL / URI • Plain text • Smart Poster • Wi-Fi credentials • Bluetooth pairing • vCard / Contact • Email, SMS, and Phone • Custom and unknown record types Write URLs to NFC tags In addition to reading, you can encode a URL directly onto a compatible NFC tag from the web app. The tag must already be initialized for NDEF messages — blank or proprietary-formatted tags are not supported for writing. The extension handles the full write flow — from encoding the NDEF payload to executing the write commands — and reports the result back to the page instantly. Supported NFC tag types: • NFC Type II — NTAG213, NTAG215, NTAG216, MIFARE Ultralight/C • NFC Type IV — MIFARE DESFire, NTAG424 DNA • NFC Type V — ISO 15693 (ICODE, TI Tag-it) Why install it? Web browsers cannot access USB smart card readers directly. This extension acts as a secure bridge — it communicates with your reader through the PC/SC subsystem and passes tag data to and from the NFC IDEAS web page. Without it, the NFC Web Reader cannot function. Compatible readers include: • ACS ACR122U • ACS ACR1252U • ACS ACR1552U • HID OMNIKEY 5022 • Any standard USB PC/SC NFC reader Requirements: • Google Chrome on Windows or Mac • Requires macOS 10.15 Catalina or later, or Windows 10 (64-bit) or later. Compatible with both Intel and Apple Silicon Macs. • A USB PC/SC NFC reader The NFC Web Reader is currently in beta. Feedback welcome at info@nfcideas.com.
