Conlux Bill Validator Now Accepts 10 and 20 Dollar Bills

WEST CHESTER, Pa., July 8, 2010 — A recent field study conducted by MEI found that higher bill acceptance leads to a 15-20 percent increase in overall vending machine sales. Accordingly, MEI has enhanced its Conlux value-priced bill validator to now accept $10 and $20 bills. The Conlux NBM-3500 validator also features a new bezel decal that visibly “advertises” that the vending machine accepts all bill denominations from $1 to $20.

Consumers most frequently carry $10 and $20 bills in their wallets because those are the denominations ATMs distribute. Accepting larger denominations enables consumers to purchase higher priced products and to purchase multiple products in one transaction.

“Upgrading the Conlux 3000 Series to accept larger bills made sense after MEI learned that 65 percent of consumers carry at least one $20 bill at any given time,” said Heidi Chico, vice chairman of the Wittern Group, the main distributor of Conlux products. “Vend item prices are rising, so vending machines that don’t accept large bills will end up losing customers to convenience stores and other retail outlets.”

All Conlux NBM-3000 Series bill validators employ strategically positioned optical sensors for protection from dirt and salting, resulting in longer life and fewer service calls. The Conlux sensors and recognition software provide high acceptance and security for all bill denominations, ensuring a positive consumer experience with each vend.

Operators can order the Conlux NBM-3500 by calling Wittern Group at 877-426-6589.
