TouchBistro uses your iPad's Region Format settings and uses the currency associated with the region you selected. To check your Region Format, tap the Settings icon. Tap General. Scroll down to International and tap that. Tap Region Format and select the region appropriate to your currency. If you've changed your region and TouchBistro is still running, close TouchBistro and restart it for the new currency settings to take effect.
If you're a Standard user, tap Purchase & About on the lower right corner of the app. Tap Purchase/Update License. Enter your Admin passcode. Tap Update License in the top left.
