Radio Frequency Identification (RFID)It refers to a wireless system comprised of two components: tags and readers. The reader is a device that has one or more antennas that emit radio waves and receive signals back from the RFID tag. Tags, which use radio waves to communicate their identity and other information to nearby readers, can be passive or active. Passive RFID tags are powered by the reader and do not have a battery. Active RFID tags are powered by batteries. MICRIt is a technology that was invented to identify the authenticity and individuality of a document using special ink and characters. They can't be faked or copied, due to the use of magnetic ink and unique fontsThe benefits of the technology include enhanced security against fraud and the mechanization of cheque processing. OMR Technology:It recognizes marks made by human beings on a document or specially printed papers used in examinations, surveys, etc. It is generally used where a large number of applicants apply and data has to be processed immediately and with accuracy. Optical Mark Readers It reads pencil or pen marks made in pre-defined positions on paper forms as responses to questions or tick list prompts. The OMR data entry system contains the information to convert the presence or absence of marks into a computer data file Optical character recognition (OCR) TechnologyIt lets you turn scanned images into text so you can turn paper-based documents into editable, searchable, digital documents. This can help reduce the amount of physical space required to store documentsBarcodesThese are symbols that can be scanned electronically using laser or image-based technology. They are used to encode information such as key identifiers (product, shipment, location, etc. ) and key attributes (serial numbers, batch/lot numbers, dates, etc. )Barcodes have less security than RFID; as they can be more easily reproduced or forgedHarsh conditions may cause enough damage or distortion to the barcode or substrate to render even the best-quality barcodes unreadable. Hence the correct answer is A, C, D, and E only.
