Making custom plastic cards to advertise your business goes beyond the concept of the durable business card. Plastic cards can also be used to track customer visits to offer incentive programs. Many people are now used to providing their custom plastic cards to be scanned upon paying for a purchase and this type of technology is easily affordable. Printing scannable plastic cards is no different from creating a plastic business card. You can also use custom plastic cards to take advantage of mobile QR technology by providing potential clients with downloadable promotions. Another good idea to consider is incorporating useful designs, such as calendars, conversion tables, loyalty cards, membership cards or rulers on the plastic cards to increase retention.
