Any suggestions for having the RFID tag create tag streams?

Hello!
I have (re)assembled the demo for the RFID reader. :hop: I've run the demo program as written against the rectangular tag that came with it. And against the four I bought the same time as the USB adapter.
The problem now is to have the program produce the numbers assigned to the tag in question, unformatted. I basically want to see a stream of numbers that each tag is wearing.
Let's say a present the tag numbered 456 to the reader. Then the debug window would show me that number. The key here is that I would want to see the numbers like that.

if tag = 12345 then debug "hello Dave" you could code that.
Show_Name:
DEBUG DEC tagNum, ": " , ....>>>>> this line shows tag ID #
' You can try this >>> DEBUG "TAG ID:", STR buf\10, CR <<<<<<
LOOKUP tagNum,
[Name0, Name1, Name2, Name3], idx ' point to first character
DO
READ idx, char ' read character from name
IF (char = 0) THEN EXIT ' if 0, we're done
DEBUG char ' otherwise print it
idx = idx + 1 ' point to next character
LOOP
RETURN
And if you want to have each card do something different then use this
Tag_Found:
ON tagNum GOSUB Routine0, Routine1, Routine2, Routine3
Routine0:

Hello!
And as it happens after a brief delay, when I spent the time working with the stamp on two other things, I have gotten it to respond accordingly.

I have pin seven on the stamp sending out my data from the tags via the classic serial output routines. :smilewinkgrin:Ideally making the rest work from that will be the big step. This is taking place with one of the sensors bought earlier.
