Details

Access Lock API provides user to apply password protected read or write access restrictions to tag memory bank. For a non-zero access password configured tags following lock operations are valid based on the memory bank selected

  EPIC TID User Access Kill
LOCK_PRIVILEGE_READ_WRITE writable only with valid password writable only wth valid password writable only with valid password Readable and writeable only with valid password Readable and writeable only with valid password
LOCK_PRIVILEGE_PERMA_LOCK Not writable Not writable Not Writeable Not readable or writeable Not readable or writable
LOCK_PRIVILEGE_PERMA_UNLOCK Tag can never be configured for restricted read or write access and is always readable and writable Tag can never be configured for restricted read or write access and is always readable and writeable Tag can never be configured for restricted read or write access and is always readable and writeable Tag can never be configured for restricted read or write access and is always readable and writeable Tag can never be configured for restricted read or write access and is always readable and writeable

Setting it up

The Following are the steps to login the reader

  • Create RFIDReader Object with appropriate params
  • Set Reader password.
  • Set secure connection type.

Creating a RFIDReader Object


// create and initialize the Reader Management object.
    mReader = new RFIDReader(hostName,ZIOTCport, timeoutMilliSeconds, "ZIOTC", "ZIOTC");

Performing operation


											  try {
TagAccess.LockAccessParams lockAccessParams = tagAccess.new LockAccessParams();
lockAccessParams.setAccessPassword(Long.parseLong(“1234”, 16));
lockAccessParams.setLockPrivilege(LOCK_DATA_FIELD.LOCK_EPC_MEMORY, LOCK_PRIVILEGE.LOCK_PRIVILEGE_READ_WRITE);
        
mReader.Actions.TagAccess.lockWait(tagId, lockAccessParams, antennaInfo)
        } catch (InvalidUsageException e) {
            e.printStackTrace();
        } catch (OperationFailureException e) {
           e.printStackTrace();
        }
