I am a bit new to rfid, but me and some of my friends have started a project on making an rfid based keyboard. But the problem is that we have two options either we use a close proxiity reader ie reading range of less than 10mm and interface it with a bluetooth device.
and the second is we use a long range rfid reader in which we can mask and unmask an rfid tag on key press.
The problem that we are having are:
1. We are not able to find a rfid rader with bluetooth capability.... there are some but they are either too costly or are too bulky.
2. Secondly close proximity readers are hard to find and we need the entire device ie bluetooth + reader combined, to be very small and light.
3. If we use the second technique of masking and unmasking a rfid tag on key press..... we dont know how to do that.
We have been searching internet local markets for the past 1.5 months but no luck as of yet.
Please can somebody help us.
Thanks in advance
