On a recent visit overseas, I saw a gentleman pull his car in front of a multi-story private garage, he then pulled out his cell phone, pressed one key, and 10 seconds later the barrier lifted. When he came out on foot I asked him how it works, and he was happy to explain it to me and handed me his phone to try it. Apparently the gate has its' own phone number and subscribers. If it has your number on the list, it will open when you call it. What an ingenious idea, I thought. No more swiped cards, take a ticket or "where is my remote control, did I leave it in my wife's car?". After looking everywhere to see where I can find one on the Internet, I finally found that they are indeed available in USA also. The only apparent downside with this company is they don't seem to answer public inquirires, but rather just work through industrial resellers, such as gate, fence, alarm companies or GSM service providers.
