If your shooters will carry a membership card or something else to which you can affix  barcode labels containing their IDPA numbers, you can use that to speed registration.  (You can offer a discount to encourage them to bring their cards.)

Assuming the barcode module is enabled, just scan the shooter's card.  (Do NOT click the IDPA # Lookup button.)

You should be able to accept the default shooter number.  If you've specified default shooter fees, the appropriate match fee should automatically appear, minus any barcode discount amount you may have configured.

Just ask the shooter what division he's shooting, then click the Print Barcode button (or hit the keypad * star key) to close this window and begin processing the next registration.  If you're not using a dedicated printer, you can hand him a strip of pre-printed club match labels and click OK.
