Can we use 2 or more SoftwareSerial in Arduino?

Issue

This Content is from Stack Overflow. Question asked by rickyslash

So I have a project that need ESP-01 (ESP8266) and Fingerprint Sensor (FM10A). Both of the component need to communicate from SoftwareSerial. For some project-related reason I can’t use the hardware-serial.

The programs works like this:

  1. The fingerprint sensor is going to capture a fingerprint and give it an ID (String)
  2. The ID is going to be sent to firebase database using ESP-01

Is it possible to make them work using 2 SoftwareSerial?

ESP-01 Pins | Fingerprint Sensor FM10A Pins

Any helpful response would be appreciated, thank you!
