I would like the system to have long-range tracking functionality and short-range reading capability from some readers for access control and at kiosks. What would you recommend?

Koketso,

Most ticketing systems use passive HF RFID because the read range is short and you can ensure that you read only one ticket at a time. Passive HF transponders based on the ISO 14443 standard support encryption and have a read range of just a few inches. The value of these tags is that when you walk up to a kiosk, it reads only your tag (or wristband with an embedded transponder). You don’t want to read the tag of the person behind you as well.

HF tags based on this air-interface protocol do not provide a long read range. You could go with passive UHF tags that support both near- and far-field reading, or you could opt for dual-frequency transponders. Lab ID and a couple of other companies offer such systems. The HF tag would be read at close range, and the UHF tag at a longer range—but keep in mind that a passive UHF tag can only be interrogated at a distance of about 30 feet or so.
