Cashless Payments, Evolved

Venues both large and small can now leverage the speed and statistic-gathering power of closed-loop cashless payments without needing to provide reliable Internet coverage or pay for expensive on-site support. Try it now with our free demo app for Android.

Offline Transactions

WristCoin can operate without any external connectivity at the event site. The terminals merely need to download the event data once before the event, after which the system can operate in a fully offline fashion, preventing connectivity drop-outs from preventing an event from proceeding smoothly

Online Statistics

When connectivity is available, WristCoin reports transactions to the central server which processes, validates, and collates them in order to provide the event organizer with live statistics on how their event is proceeding.


WristCoin's guest wristbands can be provided with custom branding and in many different form factors including silicone wristbands, adjustable cloth wristbands, and others. In fact, the "wristbands" do not need to be wristbands at all and can instead be supplied as rigid plastic cards, stickers, or even keychain attachments.

Secure NFC

WristCoin uses advanced EAL4+ certified DESFire® EV1 NFC chips featuring 128-bit AES encryption along with secured terminals in order to provide a cashless payment solution that prevents attackers from cloning cards or "sniffing" secret information.

Scalable Architecture

Since WristCoin processes its transactions offline, it can scale to support any number of attendees without difficulty. It does not matter if you have fifty attendees or fifty-thousand, WristCoin will provide the same smooth experience for guests and employees alike.

Multiple-vendor Support

WristCoin natively supports events with multiple vendors who many sell the same items, different items, or a mix of shared and unique items. By using our simple yet flexible menu specification system, WristCoin can accommodate any vendor configuration.

Using WristCoin

Create An Event

Log into your WristCoin online event administration dashboard and create a new event. Once the event has been created, you can start specifying menu items, categories, vendors, and assigning employees for your event. Don't worry, you don't have to specify the event all at once, as long as you make sure to synchronize the event data on the employee terminals after updating, you can make changes to your event whenever you want.

Order Equipment

Once you have an idea of how large your event will be, you can place an order for enough wristbands and a sufficient number of employee terminals to keep everything running smoothly. If you want custom branding on your wristbands or a different form factor altogether (cards, keychains, etc.), we can accommodate most reasonable requests. When your WristCoin wristbands arrive, feel free to distribute them at the event or send them out to guests beforehand.

Top Up

When a guest wants to add money to his or her wristband, they simply visit an employee who is trusted to handle topups and have request a topup. Once the employee has issued the topup, the balance is available without any delay and with no Internet connectivity needed.

Sell Items

To make purchases, the guest visits a vendor and informs him or her of the items and quantities the guest wishes to purchase. The vendor then selects those items and taps the guest's wristband to deduct the funds. Just like topups, the transaction is immediately processed without any Internet connectivity needed.

Request and Apply Reversals

If a mistake is made in an order, the guest visits the vendor who processed the order and requests a reversal. If the employee agrees with the request, they can then put a pending reversal request on the guest's wristband. At this point, if the employee is also trusted to approve reversal requests, they can immediately approve the request. Alternatively, if the organizer wants a manager or similar trusted individual to be required to approve reversals, the guest then visits the manager to get the request approved and balance added back to their wristband. As with all other WristCoin operations, this whole process can proceed seamlessly without Internet connectivity being available.

Close Out Wristbands

When the guest is ready to leave the event, they can visit an employee who is approved to "closeout" wristbands to have their wristband deactivated. The employee can then optionally refund the wristband's remaining balance (or some portion of it). After the wristband has been closed out, it can no longer be used for for purchases or topups, preventing a guest from receiving a close-out refund then continuing to make purchases.

Review Statistics

During your event, the WristCoin dashboard will be updated with event statistics as they become available. Once your event is complete and all terminals have synchronized, these statistics will allow you to analyze see the results of all the financial transactions that occurred at your event.

That's It!

Never has it been so easy to add cashless payments to your event as it is now with WristCoin. If you're still not sure if WristCoin is right for you, download our employee terminal demo app from the Play Store to help you make your decision.

This demo app replaces the actual server and wristband communication components of the employee app with simple placeholders, so you can get a feel for how WristCoin operates without needing any special equipment other than an NFC-capable Android phone and any NFC card or wristband to take the place of the WristCoin wristbands. Note that no data is read from or written to the card or wristband, so feel free to use whatever you have on hand without worrying about disturbing any data that may be present.
