解説

問 13

Incorrectア
Sending and receiving a patient's image and voice data over a network from a remote location to carry out medical activities is telemedicine, a use of communication networks. It has nothing to do with RFID, which reads electronic tags.
Incorrectイ
Using a cash card to deposit and withdraw cash at a bank ATM is a banking transaction based on a magnetic stripe or contact-type IC card, which differs from the mechanism of RFID that reads contactlessly using radio waves.
Incorrectウ
Reading a barcode attached to a product at the point of sale in a store to perform sales information management and ordering processing is a POS system, whose reading means is an optical barcode. It is a different technology from RFID, which reads electronic tags using radio waves.
エ
正解 RFID (Radio Frequency Identification) is a technology that reads and writes information recorded on an IC tag (electronic tag) contactlessly and wirelessly using radio waves. Choice エ attaches an electronic tag to delivered cargo and checks information about the cargo's transport history, which is exactly a typical use of RFID that reads electronic tags to identify and track individual items (traceability). Therefore the correct answer is エ.

ここがポイント

RFID is an automatic identification technology that reads and writes IC tag (electronic tag) information contactlessly and wirelessly using radio waves, and it is used for traceability such as checking transport history in logistics.
Distinction from similar technologies: barcodes are optical and need to be aligned for scanning, suited to POS, while RFID can read contactlessly and read multiple tags at once, making it strong at individual-item tracking.
