I’ve enjoyed playing with the ID-20 reader, but I now have a application where I need to be able read multiple tags simultaneously. Has anyone come across an affordable reader that has a collision detection algorithm for this purpose?
Thanks!

I don’t think you will be successful with this simple type of tag in multi-tag field. You need a something like and EPC tag which is designed to handle collisions.
thanks - after reading your post, I’ve looked around for long-range multitag EPC systems. On ebay, I see several of these:

…but I don’t think that particular model handles multiple tags. If anyone has some advice where a hobbyist could find a long range rfid reader that can handle multiple-tags-at-once, please let me know

Hello kboudy,
Have you got any news on how to do this with Arduino?

Max cost of tag is? Size?
These guys have a product that can read up to 160 tags simultaneously, but at greater range.

$20+ for an RFID tag is too much. At that price level you can get more than a dumb active RFID tag - you can get a full bi-directional radio like the XBee or its bretheran. They use 802.15.4 so transmission collision isn’t an issue
