RFID tags better but cost more.
The article discussed the application of RFID in hospital. Some of the facts discussed:
- RFID tag stores information
- Doctors and nurses carrying RFID tag readers, perhaps attached to laptop PCs or personal digital assistants (PDAs), could retrieve up-to-date information from the patient’s wristband if the hospital information system is down.
- Convenient for doctors who could refer to or update patient records from the bedside, as they make clinical observations, prescribe medication or order medical procedures.
- Implementing RFID in a hospital information system could help cut down on errors as well as reduce the clerical workload for nurses, freeing them to get on with actual nursing.
- RFID tags are more physically robust than barcode tags, are reusable.
- No Malaysian private hospital has converted from its barcode-based information system to an RFID-based one.
- Cost could be an issue, with RFID tagging systems costing about twice as much as barcode-based ones.
- RFID tags cost from 15 cents (54sen) to US$10 (RM38) each – depending on data capacity and whether the tag is “active” (carries a radio transmitter), among other things – a barcode tag only costs as much as the paper it is printed on.
- Issuing doctors and nurses with additional IT equipment ranging from Tablet PCs to PDAs and laptop PCs.
- This would add to the implementation costs to the hospital,
- Raise potential security and privacy risks for confidential patient data if the devices are lost or stolen.
Sooner or later, RFID will be a common application in hospitals, and may be in schools to.
