This is one of the issues currently blocking Usability Testing of the snapsets targeted for Pilot Stage 1.
Currently we have a problem where people key in and then key out and then sometimes key in and key out again. Some of this is due to the lack of any instantaneous feedback when the key card is read causing the individual to continue to keep swiping it. The addition of the instant feedback (
GPII-2401) will eliminate some of this problem but not all of it.
We need a mechanism to block or queue users activity when they are doing the keyin/keyout process. Additionally would be good to allow to a person to key out meanwhile the key in process of key-in is ongoing (something like cancel the key-in operation).
