ID Reader: A Broad Term

So to say "ID Reader" can mean many things. It can mean a device which reads an ID card, but sometimes its also called an ID Scanner or Card Reader or Radio Frequency ID (RFid) Reader. It really depends on the type of machine readable technology used. Sometimes even a business card scanner is call an ID reader, but when Optical Character Reader technology (OCR) is applied to reading IDs, it often provides less than stellar results, because of the inherent error rate of OCR. ID cards must be read with accuracy, which is why card issuers included machine readable technology (magnetic, barcode, RF, special OCR fonts) on the document. Hope this article helps clarify the term ID Reader.
