1. A method for testing RFID tags, comprising the steps of:

  • (a) specifying a location within an interrogation field as the location is positioned a specific distance away from a plurality of RFID tags while performing an interrogation process upon the plural RFID tags;

    (b) making an evaluation to determining whether there is any RFID tag in the plural RFID tags that is not interrogatable, and if there is, marking those interrogatable RFID tags in the plural RFID tags as interrogatable-grade tags of the specific distance and those not interrogatable as not-interrogatable-grade tags of the specific distance by the use of a shielding process;

    (c) changing the specified location to another location in the interrogation field for changing the specific distance while performing the interrogation process upon the plural RFID tags; and

    (d) making an evaluation to determining whether there is any RFID tag in the plural RFID tags that is not interrogatable corresponding to the changed specific distance, and if there is, adding another interrogatable marking corresponding to the changed specific distance on those interrogatable RFID tags in the changed specific distance selected from the interrogatable-grade tags of the specific distance and the not-interrogatable-grade tags of the specific distance by the use of the shielding process, and similar adding another not-interrogatable marking corresponding to the changed specific distance on those not-interrogatable RFID tags in the changed specific distance selected from the interrogatable-grade tags of the specific distance and the not-interrogatable-grade tags of the specific distance also by the use of the shielding process.
