kung limited ang range, it has to be established exactly how long is that range... kapag sobrang lapit, it is quite useless for surveillance purposes...

kaya ba ito mabasa ng say, super super telephoto lens from several kilometers away? maaari siguro makikita ng super powerful camera / lens ang mismong RFID, but to be able to read the code in the RFID to get a key para ma search sa LTO database? I think it is another matter...
Sir i think ung RFID eh hindi sya parang bar code na kelagan makita talaga ng scanner. Proximity based sya parang sa E pass sa slex yung range nya
