Standards
Built on the standards your fleet already speaks.
Your data moves on an open standard.
NAMA VDI 2.0 is the vending industry’s interchange format for moving locations, machines, products, and layouts between systems. Dryline is built to it at document revision 10.7, and uses it in both directions.
See what carries in each direction on the Switching page.
Import
Locations, machines, and products from a VDI 2.0 file or a CSV; planograms and opening stock from a VDI 2.0 file.
Export
Your products, locations, and machines back out to a VDI 2.0 file or a CSV. No lock-in.
File-based today
Import and export are file-based. The standard also defines a real-time exchange API; more message types come online as partner integrations go live.
Dryline reads the machine’s own meters directly.
DEX is the audit data a vending machine keeps on itself: cumulative sales and vend counts per selection. Dryline’s parser targets EVA-DTS 6.2.2 and tolerates older and vendor-specific variants.
Kept verbatim
Every DEX read is retained exactly as received; segments we do not interpret are counted, never discarded.
Checked before it is trusted
Each read carries a validation status, so a partial or malformed file is flagged for review rather than trusted blindly.
Feeds reconciliation
DEX meters are one of the three records checked in live three-way reconciliation, against dispenses and the settlement ledger.
The interfaces on the machine itself.
Cashless payments and product identification also ride on industry standards, so the reader fits your machines and your catalog fits the wider retail world.
MDB
Multi-Drop Bus, the standard peripheral interface on modern vending machines. The Rain Pay reader connects over it, alongside the coin mechanism and bill validator already there.
EMV, contactless, magstripe
The QD3 takes EMV chip, contactless tap, and magstripe. Cards are read and processed by the reader and Rain Pay; what reaches Dryline is the vend tied to the product and the settlement record.
GS1 barcodes
Products carry GS1 barcodes (GTIN), several per product, so scan-to-fill and product lookup match the same codes the rest of retail uses.
Standards questions
- Is Dryline NAMA certified?
- No. Dryline is built to the NAMA VDI 2.0 specification (document revision 10.7) and imports from and exports to NAMA VDI 2.0 files. A formal certification program is separate.
- Do I need a specific machine or reader?
- The machine needs to support MDB cashless, the standard peripheral interface on modern vending machines, and the Rain Pay reader (a Dejavoo QD3) connects over it. Most machines built in the last couple of decades support it. See the Compatibility page for the full picture.
- Can I get my data back out?
- Yes. Dryline exports your products, locations, and machines as a NAMA VDI 2.0 file or a CSV.
