Smart cards only appear to work in the PCT that issued it.

So if you are a locum you need to start getting more PCTs added to your card!
We discovered this from one of our out of town locums.
We use phase 1 and once you are used to it it takes no longer to dispense.
For phase 2 I'm not sure how I am supposed to check 500 items a day with no scripts! We will either need another 3 computers (as we have separate benches for walk-ins, deliveries and MDS) so I check from the screens or have to print them all out (then shred them after).
