To use TripleClicks X-cards, the best way can be none other than printing your SFI ID number to it and handing them over to the clerk at the EMPLOYMENT OFFICE to distribute a card to each visitor(probably unemployed or looking for some employment).
It will force them to make a try and there is where you have the purpose of your X-card served.
Hope this will give you a SOLID bunch of QUALITY Affiliates.
