Also look up on Google.com "multiplexed 7-segment display"

You should use a small controller to offload the decoding + refresh, with a serial interface (synchronous is easy).

Simply connect 1:1 to a PIC 16F, and use 3V, no extra components required. Some even have a hardware serial port.

Wiring them each time + create decoding tables is large effort and takes considerable time.

Once you have modules, you can simply deploy them, connect 3 wires, ready to use.
