\nFor low Frequency 125kHz Hitag 1 will likely give you the best range for a writable tag. This will be better than iCode and has better noise immunity in more industrial environments.\n<\/p>\n
\nUHF for longer range with passive tags
\n<\/h4>\n
\nUHF passive tags can provide reasonably long read ranges (2m for instance) and the ability to read multiple tags all coming into range at the same time, but there are some considerations. The read range it is not guaranteed as the reading of the tags can be easily interfered with:\n<\/p>\n
\nFirstly the human body is very good at blocking the signal and any tags very close to the skin or on the other side of the body to the reader can stop it working even at 1m range. One solution often used to the close to the skin issue is to use foam between the skin and the tag (>5mm works well apparently), but being on the other side of the body as it passes the reader may still be an issue. Locating tags in a helmet or in the collar of a jacket can be a good way of solving this issue if its possible.\n<\/p>\n
\nSecondly metal will affect the read range, specifically metal around the reader and metal around \/ near the RFID tag.\n<\/p>\n
\nAlso important to consider is that UHF readers can be expensive and are not necessarily available with UART interfaces (Ethernet is a popular interface).\n<\/p>\n

\nMifare general notes:\n<\/p>\n
\nRFID tags \/ cards are quite cheap as Mifare is widely used and therefore very mass produced.\n<\/p>\n
\nSecurity is available and Mifare is used for London Oyster cards for example\n<\/p>\n
\nThe range of Mifare is not as good as a protocol like ICode (which can give double the range for the same power and antenna)\n<\/p>\n
