The best way to connect with blynk wirlessly

I’m using Arduino Uno at a university project, I’ll use RFID reader with Arduino.
I want to send any information read by the serial monitor to blynk app, I used the terminal widget and Bluetooth HC05 to connect but the connection was poor and last for a minute at most.
I want to ask what is the best way to connect to blynk wirlessly especially when I’m using the same terminal sketch example. Thank you

Are you using a MFRC522? Can you jettison the Uno / HC05 and use a $2.50 USD NodeMCU ESP-12E instead?
