Fair point ... each card is unique ....

Must be one of those "I'll over complicate things" days ...

errr....

Perhaps I'm missing the point here, but what does it matter
whether you can
write to the cards or not?....

Surely so long as you can READ something (anything) off the
card, and so
long as that data is known to be unique to that card (which
seems likely if
its a personal card), then surely that's all you need to do
to use it for
personalised access control?

Just swipe the card, discover what it reads out as a serial
string, then
program that string into your HV script... what difference
does it make
whether that string is:


"LKJHDISKSSDBCJSKAOIUW23423M3NOWSWE09SKN2320FQWWLKE09302394H232K34234N2"

as opposed to:

"This is Fredd Bloggs so let him in"

/confused!/
