Question:How to set the interval time of reading same card on 721H?
Because the interval time of reading card on the newer AR-721H is 3 seconds that is longer than the former version , so if you read one card to the newer AR-721H, you must wait 3 seconds to read the same card again , once you read the same card less than 3 seconds, the reader will become no any response to presenting card , you will mistake the reader have problem and be unable to read the card.
The problem can be easy to solved to shorten the interval time
Enter programming mode *123456# (default code→31*TTTT # → *# exit (TTTT= Interval time, unit based on 10ms, range 10ms ~6000ms)
(For example, Set interval time as 1s, enter 31*0100#)
