Basic Exchange-Mode Operation

(1) “Scan QR Code”

Point the flashy light at a QR to:

pay a bitcoin “invoice”
learn more about a CK voucher
log into a Coinkite account using a QR
(2) “Make a bill”

Takes an amount, and prints a receipt that will credit your merchant account. Used typically for retail sales.

(3) “Verify receipt”

Check if CK receipt is paid, by scanning it’s QR.
(4) “Deposit Funds”

Accept fiat amounts and turn them into crypto-currency vouchers.
For existing Coinkite customers, it’s preferable for them to login first, and then do deposit.
(5) “See exchange rate”

Simply prints your current exchange rates. They include premiums/discounts as you’ve configured.
(6) “Coinkite sync”

Re-connect to the Coinkite back-end servers and get the latest settings. Not generally required.
(7) “Print/Verify Bills”

Select any outstanding retail bill for reprinting, verification (prints receipt regarding number of confirmations and so on) or archiving (which hides it).

Basic Retail-Mode Operation

(1) “Sale”

Start the sales process. Prompts for a table number (if configured) and amount due. Prints a bill to be provided to the customer, or you can hand them the terminal and they can login with a Coinkite card to pay immediately.

(2) “Scan to Verify”

Scan the QR on the bill to check if it’s been paid yet. Prints a receipt detailing the current payment status of the bill.

(3) “Coinkite sync”

Re-connect to the Coinkite back-end servers and get the latest settings. Not generally required.

(4) “See Exchange Rates”

Print a simple receipt that shows the current exchange rate between BTC/LTC and fiat currencies that you support. Does not show buy/sell prices in retail mode, only a simple summary based on the “retail” exchange rate you have defined.

(5) “Print/Verify Bills”

Select any outstanding retail bill for reprinting, verification (prints receipt regarding number of confirmations and so on) or archiving (which hides it).

(MENU) “Show Detailed Menu”

A more detailed menu with additional options is shown. Press MENU again to return to normal “open bills” display.


Card Holder Menu Operation

(1) “Print balances”

(2) “Scan to pay”

(3) “Withdraw funds”

(4) “Deposit funds”

(5) “Make an invoice”

(6) “Verify payment”

These options all work similarly to the main menu equivalents, except the Coinkite card-holder is assumed to be the counter-party to the transaction instead of the merchant.


Main Menu Keys

Aside from the numeric keys, some of the other keys perform useful functions at the main menu.

Press this key, and provide the admin PIN code to enter the admin menu.
Press this key to show the Coinkite logo and enable the back-light. Great for photo shoots. Any key to return to normal mode.
If a receipt has been just printed (within last 10 seconds or so) the FEED button makes more paper come out. The key is disabled and does nothing at other times. If you have kids, you know why we disable the FEED button.
The cancel key will always lead you back the the main menu, once there, it will lock the terminal if that feature is enabled. Otherwise, it does nothing at the main menu.

Understanding Exchange Rates

There are three main “exchange rates” involved with terminal transactions:

This is the price for bitcoins that you are selling to customers. Typically it is marked upwards from the public bitcoin price.
When buying coins from customers, this is how much you will pay for each.
Retail Transactions
When payment for good or services is made, if you are pricing goods in fiat amounts, then this exchange rate is the conversion to bitcoin from fiat. If you mark up this amount, then you are effectively charging a transaction fee. Since you may want to accumulate bitcoins, you might want to discount this amount, and so have a negative premium. You could also think of this rate as a spot price vs. a buy or sell price.
All three of these rates, plus an adjustment factor for each type of fiat can be defined on the currency page for the terminal.

The spread, which is represents your gross profit margin as an exchange, is the sum of sell and buy rates. It’s the difference between your selling price for bitcoins and the cost for acquiring bitcoins.

When setting rates, please keep in mind that your customers have good visibility into the prices of bitcoins, and they will compare your prices to competitors. Having a huge spread does not help you when possible customers complain on social media that your pricing is unrealistic.


Trouble Shooting

Signal Issues

From the main menu, try “Coinkite Sync” again.
If that doesn’t work, power the unit off by pressing and holding the “Power” button for a couple seconds and releasing, then do the same to power it up. Now let it boot and acquire GPRS signal again for a few minutes.┬áChange your location or switch to Wifi operation.

Replacing Paper

Hold the unit steady on top of a flat surface.
With the other hand, gently squeeze the transparent lid together. There are textured areas where your fingertips should be.
Apply gentle squeezing pressure and pull upwards.
Remove the empty spool. This step is easily forgotten.
Drop in the new spool of Thermal Paper with he paper lead facing down.
Pull the paper out of the compartment and close the lid by applying gentle pressure until it clicks into place.
Print a receipt of some kind as a test. The first few inches printed are often damaged.

Paper specifications

Thermal Paper
Width 2.25″, Core 0.5″, Outer diameter: 1.5″
Typical length is 50 feet.
Available at ULINE and many other sources.
It Beeps!

Yes, it likes to beep. A short time after any receipt is printed it beeps. This is to alert everyone around that a transaction has just happened. Most key presses will cause a beep, except when the key does nothing and is ignored. It also beeps randomly when it’s lonely and wants attention. Please accept this as part of the charm of this unique new platform for commerce.


Multiple Terminals

If you are operating multiple terminals at one venue, they should all be linked to the same merchant account, and should (probably) all share the same settings.

If you own multiple terminals and have deployed them at multiple locations, it would be best if they were linked to different Coinkite users. We may print receipts to the wrong location otherwise, because we assume all your terminals are at the same physical location. In time we will remove this limitation.


Wifi Doesn’t Work

The most common problem with WiFi is the encryption setting. Please try a few of the different options as terminology varies.

Also, please be aware that passwords and SSID values are case sensitive.


Exchange Rate used for Cardholder Transactions

When a Coinkite card holder visits your machine, they can use it to print a “invoice” receipt for their account. Aside from the paper used to print that, you are not a party to that transaction. However, we do use your retail exchange rate to price fiat to cryptocurrency amounts in that case.
