Hello and welcome back to my blog! Today I will continue with the subject I had last time. This particular part will probably the last one, I will change my subject afterwards.

What kinds of things could you use RFID technology for? This could be:
paying electronically and fully automatic when leaving a store
giving your children the opportunity to playback children's videos without an assisting adult; each RFID chip (e.g. put on a small card) being associated to a particular video file in a script running the necessary commands natively in a Linux environment (hiding the keyboard and mouse may be advisable in this case).
The registration of the book circulation of a library. The books being returned, for example, are being detected by an RFID reader that is receiving an unique number from the RFID chip. The computer system in use will detect in this way, what particular book is being returned by what particular individual.
De opening of doors can be RFID controlled as well. The first video linked to in this post shows a professional solution, while the other shows a do-it-yourself variety.

I hope that the link wit F/OSS is clear: there exist certain applications of RFID that have “native support” for them in Linux environments (though that does not necessarily imply that no other software needs to bee installed, e.g. see the keystroke simulation / workspace switch in the previous post).
