when an rfid is attached to an object to assist testing operations , the following problems are encountered ; the rfid of write type tends to cause a failure and is troublesome due to the necessity of rewrite each time the situation is changed , the incorporation of the reader function in a terminal block increases the cost , and the known techniques are targeted for only the connecting operation and are not adapted for a sequence test that takes the most expense in time and effort . the operations are aided by using an rfid reader and a terminal having the function for accessing a database of circuit information , rfid information , and test procedure information .
