Have a security system under your care and need supplies? Have a look at idcardcardgroup.com and see if they have what you need. I don't know about you but I'm dealing with a 125khz proximity system and mainly find suppliers in Europe or the far east. Well Idcardgroup.com is based in California and if you don't want to deal with the variables of overseas shipping and delivery (not to mention oversea customer support) this is the site for you. A recent addition to my web based arsenal, I have every feeling I'll be buying more from this company soon. I started online and then called in for more detail from customer service. The representative I spoke with was very knowledgeable and gave me several key points to check before ordering to be sure I was ordering the actual product I was looking for. This almost is a rarity today as it feels like a website will sell you anything just to make the sale, while this business is interested in the long term customer/supplier relationship.
I like that from people so it's natural that I love it as a company philosophy.
The site itself is a tight format with almost too much information displayed in the space used. Not inspiring in appearance, it does however make finding what you're looking for fairly easy. Know what you need and you'll find it, don't know, customer service will help. "Meh" appearance but "Love it" customer service drops it nicely into "Cool".
