RFID with reading distance about 1 to 2 metres?

Friends,

Do you know which RFID reader for 1 to 2 metres reading distance ?
Can I use TX transmitter ?
Thanks

sensitivity and complexity increases with frequency and low F needs more cost with large copper coils. BPF Q increases SNR and improves sensitivity, hence range.

I want to transmit the ID with Tiny13A, with this

, but if the transmitter has a distance more than 2 metres to the receiver, it will disconnect itself, is that possible ? how detect the distance in code ?
thanks

The frequency is 433Mhz,
I attached the datasheet of the receiver and transmitter, how can I create a code that the receiver or transmitter will disconnect if the distance between them is more than 2 metres ?
thanks
