How to write boolean value with rfid?

I am new to factory io so pardon if this is simple. How can write a boolean value with rfid? It seems that rfid only allows write int values.

Hi kijeson933,
There is no way to directly write a boolean value to the RFID Tag memory, sorry.
You will have to pack the boolean value into an int, and then read/write the int value.

Thanks for the reply. As a follow up. Is there a way to throttle the emitter on a conveyor?
