Shopping for electronic shelf labels can feel like building a computer from parts. The tags come from one place, the gateway from another, the software is a separate subscription, and getting your prices into it is up to you. For a large chain, that's normal. For an independent coin shop, gun store or other specialty retailer, it's often the difference between a system that runs and one that sits in a box.
What a typical ESL purchase includes
Most ESL systems have four parts:
| Part | What it does |
|---|---|
| Tags | Display the price at the product |
| Gateway or hub | Sends prices to the tags wirelessly |
| Label software | Where items and prices are managed |
| Price source | Where the prices come from: you, your POS, or a market feed |
The question is how many of these come from one company, and how many you have to assemble yourself.
The mix-and-match model
With large ESL vendors, these parts are often bought and priced separately, usually through resellers. For example, U.S. reseller WAND Digital lists SoluM's gateway, its labels and its AIMS software as separate items, with AIMS label service at $630 to $3,150 a year. SoluM describes AIMS as connecting to other systems through a REST API, which is how prices get in.
Minew's MinewTag line works similarly: its demo kits bundle tags and a gateway with a cloud platform license for six months or a year.
This model is flexible, but it puts several jobs on the store:
- Coordinating vendors. Hardware questions go one place, software questions another.
- Integrations. Someone has to connect your price source to the label platform.
- Renewals. Software licenses expire and need tracking.
- Troubleshooting. When a tag shows the wrong price, which part failed?
The all-in-one model
An all-in-one system comes from one company: tags, hub, software and, where it applies, the price source. One vendor owns the whole chain, so a wrong price on a tag has one place to start.
PriceTaglet is built this way. It makes its own tags and its own software. The system includes E-Ink tags, a pre-configured hub that plugs into an outlet and joins store Wi-Fi, a browser dashboard, and a live spot price feed for gold, silver and platinum. There's no app to install, and PriceTaglet says most shops are set up in under 15 minutes without a technician.
Why it matters for coin shops
Coin and bullion prices follow the market, so the price source isn't optional. In a mix-and-match system, a coin shop has to buy market data, build the recalculation logic and connect it to the label platform. In PriceTaglet, tags are configured by metal, weight and karat, and the hub recalculates prices automatically when spot moves. That's the clearest case for all-in-one.
Why it matters for gun stores and other specialty retailers
Gun stores and other specialty shops don't price from a metals market, but they share the same constraints: small teams, no IT department, and prices that change often. Ammunition follows supplier costs, used and consignment guns move on markdown schedules, and promotions start and end. One dashboard to manage tags, and one company to call, keeps that manageable.
PriceTaglet's dashboard supports manually set prices and its own tag designs, so the same system works on a gun counter or an accessory wall. Features specific to those stores, such as markdown schedules and point-of-sale connections, are still being developed with early partners.
Accuracy is the payoff
Whatever the store, the goal is the same: the price on the tag matches the price at the register. In many states, inspectors check this using the NIST Handbook 130 procedure, under which a store passes at 98% accuracy or better. The fewer handoffs between your price source and your tags, the fewer places that match can break.
Questions to ask any ESL vendor
- Do you make the tags and the software, or resell someone else's?
- What does the software cost after any trial period?
- Where do prices come from, and do I need to build an integration?
- Who do I call when a tag is wrong, and where is your support team?
- Can I set it up myself, or do I need an installer?
