What is RFID
RFID is a short form for “radio-frequency identification”. It refers to a technology that involves digital data encoded in RFID tags or smart labels. It allows readers to capture via radio waves. We can use a device that stores the data in a database. RFID is like barcoding in the form of data from a tag or labels it captures. However, it has had several advantages over systems that use barcode asset tracking software. The most notable is that RFID tag data can be read outside the line-of-sight. Whereas, barcodes must be aligned with an optical scanner. If you are considering implementing an RFID solution, take the next step and contact the RFID experts at AB&R® (American Barcode and RFID).
How does RIFD work
RFID belongs to a group of technologies referred to as Automatic Identification and Data Capture (AIDC). AIDC methods automatically identify objects, collect data about them. And enter those data directly into computer systems with little or no human intervention. RFID methods utilize radio waves to accomplish this. At a simple level, RFID systems consist of three components: an RFID tag or smart label, an RFID reader, and an antenna. RFID tags contain an integrated circuit and an antenna. We use antennas to transmit data to the RFID reader (also called an interrogator). The reader then converts the radio waves to a more usable form of data. Information collected from the tags is then transferred through a communications interface to a host computer system. There the data can be stored in a database and analyzed at a later time.
How safe is RIFD
RFID(radio-frequency identification) credit cards are as safe as EMV chip cards, and data theft concerning RFID cards is uncommon. Because of how these cards transmit information and what information is shared, hence it is difficult. RFID card technology uses radio frequencies to communicate with card readers. Whilst, for that communication to happen, your card must be close to the reader.
Moreover, you can’t have barriers around it that prevent a connection (such as a wallet with other cash and cards inside). Unlike traditional credit cards, RFID cards use one-time codes to complete each transaction. Using your RFID card creates a new code thus, it makes it more difficult for your information to be compromised. While it is technically possible for a thief to find a way to skim your RFID card, they would have to work quite hard to do so.
RFID systems use radio waves at several different frequencies to transfer data. In health care and hospital settings, RFID technologies include the following applications:
- Inventory control
- Equipment tracking
- Out-of-bed detection and fall detection
- Personnel tracking
- Ensuring that patients receive the correct medications and medical devices
- Preventing the distribution of counterfeit drugs and medical devices
- Monitoring patients
- Providing data for electronic medical records systems
- The events associated with RFID The FDA is not aware of any adverse.
- However, there is concern about the potential hazard of electromagnetic interference (EMI) to electronic medical devices from radio frequency transmitters like RFID. EMI is a degradation of the performance of equipment or systems (such as medical devices) caused by an electromagnetic disturbance.
