That information helps greatly. This post is only tangentially about the chip, and more about in sales/marketing strategy landia. If you're not interested in that then immediately stop reading and go to the next post.
Given what you've said I would suggest that you get two chips and you don't buy business cards. Instead spend the $ on more chips! (A popular refrain on this forum!)
Yes, no business cards: Radical, but don't have one, it's a waste of $ b/c people promptly forget about them, just throw them in a drawer or trash them. Save your $ and get more chips. You're in gaming: of course you don't have a business card, why would you? Your target customer needs chips (and tables, etc.). So it's a natural play, not a gimmick. Have one style of chip freely available lying around in your booth and encourage people to take one for their colleagues, etc. A chip is going to be handled and recognized every time someone opens their drawer, it's physical so it will be played with, and it's something unique to bring home from a show, so people who get one will say "cool, huh?" I will be really surprised if attendees don't gravitate to your booth just to get their own chip: booth traffic is exactly what you want and it's why you're spending money on a booth in the first place. Hence I encourage you to get more chips than you think you need. Here's conceptually how I would approach it and some observations on the chip above (I don't know your budget or how important this show is, so modify as appropriate):
Chip 1 (post #23): I like a lot of the changes that you've made, but let me suggest some tweaks. Instead of the two suits on the obverse use two dice. Delete the Maple Leaf on both sides of the chip: they are distracting and I don't believe that a Maple Leaf has any special affiliation with gaming based on the Canadians that I have met (if you want to keep them for some reason, then replace each of the two suits on the back with a Maple Leaf instead of dice). Delete "chanmanpokertables.com" on the front of the chip: the text will be unreadable if it's 39mm (and people can figure the URL out from your email anyway). The "w" in Northwest is not capitalized (there might be a colloquial reason for doing so, but it is not general usage). Delete the "ChanMan" logo on the back and use that whole back canvas to emphasize your message. I would spend some time thinking about how to make the message more impactful. I do like your current message but it's wordy. The message (preferably a question) can be longer or have larger text now that the ChanMan logo is gone: Perhaps something like "Do you deserve custom, handcrafted gaming furniture?" Do you think that you can find me one person (especially on this forum) who will say no to that question? People are now thinking about what you do and how much they deserve it. That is much more powerful than you saying what you do.
Chip 2 (the "special, limited edition" chip): Same front, same general back, but instead of the current "ChanMan" (which I have advocated deleting) and the current text, do something like adding serial numbers to them and voila: "special, limited edition" chips. Hold a raffle at some point for some gaming related prizes - doesn't even have to be at the show: do it at some later time. ("Go to my website on blah blah date and discover if you won! Driving traffic to you and another touch reinforcing what you do to them.) Change the color of the outside rings and on the rolling edge to a contrasting color so that they are immediately distinguishable at a glance from Chip 1. (Orange would be my suggestion as it is a power color, typically is a higher value chip and combines well with blue.) Potential raffle prizes could include - dare I say it here - dice chips (or Milano's or something reasonable) or nice playing cards, or a high quality poker table and chips delivered for "your next poker night," or whatever as long as it is low cost to, and easy for, you. Critically, to get the "special, limited edition" chip
the recipient has to do something for you. These chips will not be on your booth table, but only available from you (or whoever is at the booth with you). No one can get more than one chip - so you have to say "no" when people want to get one "for their friend" etc. - because the chip is designed to get each person to do what you want them to do. Things that they can do for you include (purely as examples): provide you with a business card or write down contact information or tell you what they do or introduce you to a potential client or tell you the name of someone who may need your services. Obv. you will acquiesce to anyone who can't/doesn't want to do that thing and nonetheless give them a chip. People will really want this special chip. Every time someone collects a regular chip, you should ask them if they have any interest in a raffle which requires a "special, limited edition chip." They will be. Your response should be: "OK, I will give you one, but would you mind doing something for me first?" Then ask them to do that thing. They will do it. The text on the back of Chip 2 should say something different from Chip 1 like: "Winners go with Tony!" or "Make your next night special with Tony!" or "Get what you deserve from Tony!" Apologies, these are a little hokey, but it's all I have to offer right now. This chip will create buzz, because show attendees will ask others: "Did you get the orange chip from Tony?" Everyone now has two pieces of your contact information: they will keep the "special" one and have a much higher likelihood of giving the other one to a prospective client. That's what you want: you are now memorable. In addition, you are expanding your customer base, and getting ideas for people you should be reaching out to.
As you can see, my philosophy is that your actual goal at any conference should be to get other people to help you broaden your target customer base so you want to get OTHER people's business cards and THEIR ideas on expanding your business. By giving someone something physical like a chip they will generally feel obliged to leave you with something, and that something should be their card or an idea that helps you. (If you have any interest in learning more do a search for "Cialdini Reciprocity" - it's interesting stuff if you have an interest in sales/marketing esoterica.)
In addition (as we are marketing/sales landia in this post), let me suggest that you sign up for Evernote Premium (
www.evernote.com) annual plan ($49.99 per annum: less than a latte a month). IMHO it is one of the critical tools in existence for sales/marketing (especially smaller businesses). The reason to sign up for premium is that it has a very cool feature: you don't need to
get someone's card, you just ask to
borrow it for 10 seconds. Once it is in your hand, you take a picture of the business card within the evernote app on your phone, and evernote will create a note of that card, populate that note with the text on that card, retain a picture of the card, and allow you to immediately send (a) an email to that person with your contact information and (b) send them a LinkedIn invitation. Immediately give that card back to that person or throw it away as you no longer need it because you now captured their information and it is easy to search for! Your Evernote data is available on any device that has internet connection, a web portal, and you can download your Evernote notes locally to your phone or your computer. If you look up someone's name from within the app it will find the note for the card, allow you to select their tel # which you can automatically dial, or select their email and it will create an email addressed to them. You can the same thing to that pile of cards on your desk that you never look at and throw them away afterwards. Obviously I'm a huge Evernote fan. This process is really easy and takes less than 30 seconds per person, and a lot of people are intrigued when they see it because they have never seen it before: another reason for them to remember you.
The above is more like $2, US. I've seen the exchange rate.
