Scratch off stickers?

is he looking for a sticker he can apply to his existing cards or is he looking for whole new cards with the scratch off built in? I don't think it's a sticker, it's kind of a coating.

 

It is a coating that is put on during the offset printing process.
I hope your customer knows that it's not going to be cheap to do this.
Find a mid sized offset printing company in your area and stop in and talk to them about it.
Ask for samples to look at to check out the quality.

 

I'm more curious about what he wants to put on the back that is worthy of a scratch off?

and good luck meeting price point w/quality.

Believe it or not, he may be better off with pull-tab cards. I'm not kidding.
Don't hold to what I'm saying as some sort of wise advise or knowledge, but I will say that I'm sure what he wants can be achieved with other methods that in the end will deliver the same effectiveness at a lower cost with the same impact with good quality, rather than a good idea that ends up not being taken as worth anything by the end user.

 

Why not print a bunch of kiss-cut circles of his logo patterned across a sheet on low tack vinyl and apply them to the cards? He'd be happy to apply them himself to save some $, and you'll come out ahead by not having to do that while selling an option that makes you money & makes him happy.

 

On a side note about that - There's no saying the label can't be removed and re-applied. To prevent that would bring it to be a Gerber Edge tamper foil short run. Unless you can sell the novelty of the idea with every card having a maximum discount that he would be willing to honor assuming it's faults will be taken advantage every time - there are some major leaks. Realize what they are and sell, sell, sell.

 

Scratch off coatings can be applied with a screen print process as well. It's usually more cost effective on smaller runs.
