◆ UfrGetBadSelectCardNrMax()
The function returns value of maximal unsuccessful card selections, which is set in reader.
- Parameters
-
| bad_select_nr_max | pointer to number of unsuccessful card selections |
- Returns
- Operation status
◆ UfrSetBadSelectCardNrMax()
The function allows you to set the number of unsuccessful card selections before it can be considered that the card is not placed on the reader.
Period between two card selections is approximately 10ms. Default value of this parameter is 20 i.e. 200ms. This parameter can be set in the range of 0 to 254. This is useful for asynchronous card ID transmission, if parameter send_removed_enable in function SetAsyncCardIdSendConfig is set. Then you can set a lower value of the number of unsuccessful card selections, in order to send information to the card removed was faster. A small value of this parameter may cause a false report that the card is not present, and immediately thereafter true report that the card is present.
- Parameters
-
| bad_select_nr_max | number of unsuccessful card selections |
- Returns
- Operation status
