Two of our Hybris Labs prototypes need a tag-to-YaaS mapping. Infinite Cart uses NFC (Near field communication) where the Tag ID is mapped as product code (SKU number). For the Changing Room prototype we are using RFID (Radio-frequency identification) tags. When we started with this prototype you had to hold a RFID tag near an RFID scanner and then had to check the log files to find its ID.
With the RFID Action Reader, which we’re also using for our Expose prototype, you can read the RFID
ID on a Raspberry Pi. But I also built a custom made Arduino Shield with an Indy RS500 chip (from Impinj), which sends the the RFID value via USB port. This made life much easier and gave me the idea for Project X-Ray.
The idea of the X-Ray Project: you can use any scanner (Barcode, NFC or RFID) to automatically add the scanned product code. The name of the Project: Tom Brady can scan the defense of an American Football team, but Superman has X-Ray Vision.
YaaS Builder Module
The X-Ray YaaS Builder Module lists all products (or variants, if you use them) with its image, product name and an editable product code.
The selected product will be saved when the user hits Return or a scanner sends a Return ‘\n’. This allows you to use a simple barcode scanner, or a NFC/RFID scanner with an Arduino Leonardo which uses the HID protocol. The HID (Human Interface Device) protocol simulates a keyboard. In this case my RFID or NFC scanner works like a keyboard and I could use it here (RFID: E28011606000020507B259A0).
An alternative is WebUSB. In this case the scan result will be only available in the browser. Another effect is that it is independent of the keyboard layout (HID shows other characters, if you’re using Dvorak as keyboard layout).
If you’re interested in this Builder Module you can subscribe it as Private Package with the Version ID 58a310e5b11af50013e341af.
Some technical stuff
The YaaS Builder Module is a static web module using RESTangular. The module runs on Cloud Foundry. For the X-Ray demo I’ve been using some images from the RetroPie project. You may have heard about our Arcade Machine here at Hybris? We are all ‘retro‘ now :)
And because I’m lazy, I’ve built a tool which adds products via YAML file into YaaS. The name of this tool: Megablast … yes, from the retro game Xenon 2 Megablast.
