Lucky Lock key cards for trade fair promotions

The Lucky Lock keys draw more visitors directly to your stand, with curiosity and the desire to win.

While the visitor wonders whether the key will open the safe and win the Tablet, you can look forward to new customers and additional sales.

FAQ

How to make your trade fair a success!

How does Lucky Lock work?

To win, your customer must come to your stand and find out whether their key opens the safe or the chest.

You decide in advance how many keys are winners and when the winners will be distributed.

The thrill ensures a high level of attention and additional visitors with increased sales at your stand.

How high is the response rate?

Response rates of over 70% are common if the route is short and the main prize is attractive.

If your potential customer has to walk through several halls, the response rate drops significantly.

When sending by post, it depends on whether your customer comes to the trade fair at all, in which case a few percent response rate can be expected.

How do I get the key to my potential customer?

Distribute cards with keys directly at the trade fair.

Book in advance so that your card with key hangs in the organizer's goodie bag or with a note on the lanyard trade fair badge to guarantee success at the trade fair.

For presentations and keynote speeches - distribute key cards to the seats.

Handing over a Lucky Lock key card

How do I get my customers' business card?

Collect the business card or scan the visitor badge before your customer tries their luck at the safe.

An additional chance to win can be announced on the back of the key cards for all non-winners – this is how you get e-mail addresses with the appropriate consent.

How do I make sure that the main prize is not awarded on the first day?

In order to maintain the excitement throughout the trade fair, the winning key can only be distributed on a later day of the fair.
