TR515/TR510 will show “BUSY” when it is downloading the data. At the moment, the card won’t be accepted when you present (swipe) the card to TR515/TR510. If the interval time of auto-download in the software is set too short, it will cause TR515/TR510 to download the data automatically quite often. Set the interval time of auto-download longer to avoid the busy situation.
