I am currently working on a standalone device to accept XLM in stores. It's a battery powered device with an e-paper display. A web app is used to enter the amount (in fiat) and to monitor transactions. When the transaction has been confirmed the device informs the customer through it's display. While all elements of the system will be open source and open hardware I might offer a hosted backend when I am done.

Very cool idea! So this is similar to Square app that I use when selling my art at festivals? I could use this hardware device to accept Lumens? How does the customer pay, QR code scan?

jeremy82many Yes. It displays a QR code that the customer can scan. I am not sure if that is simple enough though.

QR Code is easily generated, this should get you started. https://github.com/s-a-y/stellar-qr

albimcleod thank you. While I need to use another library on my tiny embedded chip, I was looking for some information about what data to put in the QR-Code. The problem I have is more about usability though. There is no wallet for iOS (in the store) that allows scanning QR-Codes and people might not like to keep their funds on a phone. I’ll have to look into it.

Have you tried Centaurus? It says it has iOS support and the android version has a qr reader. The library I pointed you too has the format if you look into the code, otherwise this is the minimum for mainnet. Works with Stargazer. {"stellar":{"payment":{"destination":"${accountNumber}","amount":${amount}}}}

After a lot of research I figured that there is no good consumer wallet for iOS. Until there is I don't see a chance for mass adaption. So I decided to extend my portfolio before I even have one and start with a new iOS wallet especially optimized for simplicity. It is (in a way) meant to pay for goods in retail stores. Here is a screenshot of the first prototype: http://www.hodldeck.com/wp-content/uploads/IMG_3193.png

You can now sig up for the iOS Wallet Beta: https://goo.gl/forms/Km4JXMwdpcZC7vCJ3

There's no iOS wallet because Apple has a whitelist of crypto currencies they allow software for, and AFAIK Stellar is not on the list.

Here is my first update: Rocket Wallet will eventually support QR-Code scanning on iOS, that's why I continue working on the device (I will build a wallet optimized for retail customers later). Some of you have donated a total of 30XLM!!!!! That's awesome and shows that people are interested in the project. Thank You so much!! I will buy another development board from the donations. (I am adding a donation counter to the website while we speak). I transfered this and some more to a dedicated wallet ( tips*hodldeck.com or GCEVAWUOPEZRLEHG35CBHRZETAX3O4EQBKUKOU62GZRGOMZX4QUCA2ZN ) for HODLDeck. The money inside this wallet will be used exclusively to fund the project I also added a gallery to the website ( http://www.hodldeck.com/#Gallery ). Check it out, I will add more images from time to time. The dev board I am using crashes when tryig to validate the stellar Horizon API server (certificate is too big), which means I can not connect to it directly (which was not the plan for the long term, but would have sped up development in the beginning) I started writing the backend in node.js and express. That's it for now. See you next time.

Introducing HODLDeck - POS device to accept XLM in retail

BlackMac

I am preparing the How To booklet that can be downloaded and comes with the kit.

BlackMac Well done! I'm glad you're making such great progress. As I've mentioned previously, we're planning to test your product in NYC at one busy coffee shop. I'm eager to see more updates soon!

savebattgo

xirkle we are going to try this in Asia too. Singapore for a start. besides payment, can this be adapted for simple banking? BlackMac

BlackMac

I am looking forward to ship HODLdeck to all of you.

Here is the first prototype of what the kit might look like when it arrives:

Another Update

All the hardware for the first three kits has arrived from China. While the recipients for the first two kits have already been chosen the last one will be chosen from those who tweet the most compelling reason why I should send them the kit.

Please tag @hodldeck ( https://twitter.com/HODLdeck ) in your tweet and follow, so that I can send you a PM and ask for details.

BlackMac

Oh... and by the way, I ordered a handful of these: RFID

chaynes

Pretty cool. I have 50 Raspberry Pi Zeros that are just waiting to be used for a project, think I found a use for one lol.

BlackMac

chaynes I was thinking about building a pi zero w version, but it’s too expensive and too overloaded for what I wanted to achieve. But when I realized that the ESP could not handle the ssl cert of the horizon server I was about to give up. I might reconsider also offering a pi version.

chaynes

BlackMac

I fully intend on looking into this when I have time. If I make any progress on getting it working on a pi I will absolutely share.

If you ever need bulk pricing let me know, I can probably get you the same deal I got. I use a supplier in China that has been nothing but great to work with.

BlackMac

This is how HODLdeck will work when the RFID capabilitY has been added to the device:

Customer can buy a HODLdeck card in fiat or XLM
Customer buys goods at a shop
Customer touches HODLdeck device with the card (this is the moment new fiat cards become XLM cards)
Done

Alternatively customers can scan cards using the HODLdeck app.

Scanned cards require transactions to be confirmed on the phone.
Scanned cards can be recharged with a credit card or in participating shops

Customers do not need to understand crypto or stellar, but can still use it and when they use XLM cards they can even speculate with XLM (and hodl ? )

savebattgo

Can it be used to monitor shipping of items, just scanning barcodes or products to track origin. What about adapting it for use as an in-vehicle IOT to scan for parking fee

BlackMac

savebattgo there are better blockchains for supply chain tracking (VeChain) and IoT micropayment (iota, nano). HODLdeck is just meant to make Stellar useable as a currency for in-store payment. The main focus is usability.

Current state of the hardware:

Damn. No reward. But it won‘t keep me from building this.

Question:
Does a merchant need a BitLicense in order to accept virtual currency as payment for goods or services?

Answer:
No. A merchant does not need a BitLicense in order to accept virtual currency as payment for goods or services.

Hey BlackMac!

Do you have any new updates on your project? Can I buy one of your kits now? How much?

By the way, is there a way to instantly convert XLM into USD immediately after a customer makes an in-store payment? Do you know of any blockchain vendor that offers such a service?

CoinPayments.net seems to offer something like this, but it's through CoinBase.

CryptoMediaNetwork

xirkle Tillbilly are creating a solution to this problem.
