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.

Abstract
The present invention provides a method and a system for testing RFID tags, which utilizes a way of adjusting the distance between the RFID tags and interrogator or adjusting the power of the interrogator accompanied with a shielding procedure for testing and classifying the RFID tags. By means of the method and the system of the present invention, it is capable of judging the efficacy and good and bad of the RFID tags, while the interrogatable distance of the RFID tags is capable of being tested effectively.

9. A method for testing RFID tags, comprising the steps of:
-
(a) applying a specific interrogation power for interrogating a plurality of RFID tags in an interrogation field; (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 interrogation power and those not interrogatable as not-interrogatable-grade tags of the specific interrogation power by the use of a shielding process; (c) changing the specific interrogation power for interrogating 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 interrogation power, and if there is, adding another interrogatable marking corresponding to the changed interrogation power on those interrogatable RFID tags in the changed specific distance selected from the interrogatable-grade tags of the specific interrogation power 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 interrogation power on those not-interrogatable RFID tags in the changed specific distance selected from the interrogatable-grade tags of the specific interrogation power and the not-interrogatable-grade tags of the specific interrogation power also by the use of the shielding process. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A system for testing RFID tags, comprising:
-
a conveyer belt section, having a conveyer belt configured therein to be used for carrying a plurality of RFID tags; an interrogation section, disposed at a side of the conveyer belt and capable of forming an interrogation field for reading data in the RFID tags of the plural RFID tags that are situated inside the interrogation field as they are being transported by the conveyer belt; a position adjusting section, for adjusting a distance between the conveyer belt and the interrogation section as it is coupled to the interrogation section; a shield section, for provide a specific shield to the plural RFID tags so as to define the amount of RFID tags capable of being interrogated by the interrogation section as the shield section is designed to be mobile for enabling the same to selectively shield at one RFID tag of the plural RFID tags; and a moving section, capable of performing a displacement operation for enabling the shield section to move accordingly as it is coupled to the shield section. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A system for testing RFID tags, comprising:
-
a conveyer belt section, having a conveyer belt configured therein to be used for carrying a plurality of RFID tags; an interrogation section with adjustable output interrogation power, disposed at a side of the conveyer belt and capable of forming an interrogation field according to its output interrogation power for enabling the RFID tags of the plural RFID tags, transported by the conveyer belt and thus entering into the interrogation field, to be interrogated; a shield section, for provide a specific shield to the plural RFID tags so as to define the amount of RFID tags capable of being interrogated by the interrogation section as the shield section is designed to be mobile for enabling the same to selectively shield at one RFID tag of the plural RFID tags; and a moving section, capable of performing a displacement operation for enabling the shield section to move accordingly as it is coupled to the shield section. - View Dependent Claims (25, 26, 27, 28, 29, 30)
