Does anyone have tips for Washington bouncers?

I'm heading to Seattle next week and I'm a bit nervous about the security there. I have a Washington novelty ID that looks great, but I've heard that bouncers in the Pacific Northwest are very thorough with barcode scans. Do they usually use the BCS scanners or something more advanced?

I've been practicing my zip code and the cross streets for my address. I also have a backup credit card with the same name. Is there anything else I should be prepared for? I've heard they sometimes check the ghost image transparency under a very bright light. Any advice from locals would be great!
