NFC scanning is much easier to use due to its tap-and-scan technology. While barcode scanning requires you to hold your device or the barcode just right to capture the code, NFC requires only a light tap of the tag-embedded item to your device.
With Android phones, there’s no need to purchase a special reading device because NFC scanners come standard. Simply tap your Android device to an embedded NFC tag and you’ll pull data from the ID card, ticket or label.
As a subset of HF RFID, NFC operates at 13.56 MHz and typically requires very close proximity to scan – 1 to 6 inches. NFC radios are low cost and can be found on most smartphones.
While UHF operates at 856-960 MHz and a has a much larger range depending on the tag and the reader – between 1 to 40 feet – the technology is much more expensive requiring specialized readers compared to consumer grade devices.
