One of the features of IDBLUE.HF and IDBLUE.UHF is having an internal real-time clock to allow time-stamping of each tag scan. The IDBLUE driver/sdk returns the timestamp (and with HF, it also returns the tag UID) on a scan.
//Setup the hfResponseHandler as needed IHfResponseHandler _hfResponseHandler = new HfResponseHandler() { @Override public void readTagIdResponse(IDBlueCommand command, ReadTagIdResponse response) { // response.async() indicates whether the tag scan resulted from // a button press of IDBLUE (async), or from a call to readTagId (sync). String async = response.async() ? "Async Tag ID" : "Sync Tag ID"; RfidTag tag = response.rfidTag(); IDBlueTimestamp scanTime = response.timestamp(); String tagId = tag.toString(); String ts = scanTime.toString(); OnSuccess(READ_TAG_ID_MODE, String.format("%s: %s, Timestamp: %s.", async, tagId, ts)); } }
Note that the IDBLUE driver/sdk does not set the timestamp on the reader as it is the responsibility of the client app to call setTimestamp() at some point in order to setup a valid timestamp on the reader.
If you have any further questions, you can contact IDBLUE Support.
