With this release, Gray Water Ops has finalized the design of its technology that was previously available in prototype mode, and secured the patent for the coins. These custom coins can serve as a piece of branded merchandise with the added utility of programmable NFC integration.

The coins can be programmed to instantly transmit contact information or execute commands when in contact with an NFC-compatible device, eliminating the need for standard business cards. The tokens are also infinitely reusable, eliminating the need to use paper business cards and generating no waste.

Although the use cases for these coins have not yet been fully explored given that the patent was secured earlier this year, so far they have seen a wide adoption at conferences and trade shows where high-volume foot traffic makes efficient communication essential. The NFC challenge coin simplifies the process of contact information transfer down to a single motion, making it extremely efficient in time-sensitive situations.

One reviewer stated, “I ordered some military coins in May 2013 and was so impressed with the speed and quality that two months later I placed a second order for coins for my local Rotary club. They turned out great as well, and are used as thank you mementos for each week’s guest speaker. I regularly have people ask me where I sourced them when I hand out either of the coins. I gladly point them to Gray Water Ops when I get the question.”

Challenge coins have historically been used to show affiliation to an organization, and distributed to trusted partners as a sign of goodwill and membership. With Gray Water Ops’s advanced technology, challenge coins now have a new utility as a communication tool while still maintaining their usefulness as a symbol of association.

These coins are fully customizable, with soft or hard enamel and laser-edge engraving on both faces. Interested parties can provide their own graphics and logos, or they can work with the Gray Water Ops in-house team of designers to create professional graphics.
