µFR Nano Online is a great choice for a standalone device.
Its “Master mode” allows you to send all NFC tag read data to a predefined server.
The HTTP POST request method is used for the data sending. The user can choose to send cards/tags serial numbers only or to send all the tag content.
Basic µFR Nano Online information
µFR Nano Online is an NFC Reader with WiFi and Bluetooth connectivity. Optionally, Ethernet connectivity is also available through an adapter board.
µFR Nano Online has configurable GPIO (4 pins) and UART for connecting additional NFC Reader.
The device also features external EEPROM and optional RTC (Real Time Clock).
Device composition and compatibility
Nano Online is comprised of two main boards:
1. µFR Nano NFC Reader
2. ESP32 add-on board
Because this device integrates µFR Nano, it enjoys SDK and features our other µFR Series devices do.
– SDK in multiple programming languages
– Cross-platform libraries
– NFC tag emulation
– Digital Signing support
– Working with MIFARE cards (Classic, Ultralight, Ultralight C, DESFire, DESFire Lite, Plus), NTAG2xx, NTAG DNA, JCOP (Java Cards)…
– Ever upgrading firmware, library, and software SDK support
– Browser extensions (Chrome, Firefox, and Opera)
ESP32 add-on board provides:
– Additional communication types such as Wi-Fi (UDP, TCP, HTTP, Web Socket), Ethernet (UDP, TCP, HTTP, Web Socket), Bluetooth (BLE, Serial, and HID)
– External device communication ports such as configurable GPIO (4 pins) and UART TTL
– EEPROM, RTC (Real Time Clock), and battery for RTC
– 2 RGB LEDs.
– Allows you to write your own software inside the device itself. Supports IDF and Arduino code
µFR Nano Online supports many different operation modes:
1. WiFi Slave – device acts as regular NFC reader but communicates via WiFi with a host (PC, mobile…).
2. WiFi master – device sends all scanned card information to predefined server address via HTTP. It doesn’t need any host (PC, mobile…). It just requires a WiFi connection. The same functionality also applies to the Ethernet version.
3. Bluetooth Serial – device acts as regular NFC reader but communicates via Bluetooth Serial protocol with a host (PC, mobile…).
4. Bluetooth BLE – device acts as regular NFC reader but communicates via Bluetooth Low Energy protocol with a host (PC, mobile…).
5. Bluetooth HID – device acts as a keyboard emulation device (for example like a bar code reader). It sends card UID to a paired device’s text input field.
