What is an exchange rate display? A complete guide
Every exchange counter has one: the screen that tells customers today's buy and sell rates. Here is what a good one shows, how the rates get onto it, and what to look for when you choose one.
Walk into any exchange house, bank branch or airport bureau and the first thing a customer looks at is not the cashier. It is the board on the wall. Before they reach the counter they have already compared your US dollar rate with the shop next door and decided whether to stay. That board is the exchange rate display, and for a business that lives on margins of a fraction of a percent, it is one of the most important pieces of equipment in the branch.
This guide explains what an exchange rate display is, what it should show, how rates get onto it, and what to check before you buy one.
What an exchange rate display is
An exchange rate display is a screen or sign that shows the rates at which a business buys and sells foreign currencies. People call it many things: a currency exchange rate display, a forex display board, a currency rate board, an FX rate screen or a money exchange board. They all mean the same thing: the public price list for currency.
For decades these were physical signs: printed cards slotted into a frame, then split-flap boards that clattered as the digits turned, then LED panels with red or amber seven-segment digits. Today most new counters use a digital exchange rate display: an ordinary TV showing a rate board drawn by software and updated over the internet.
What a good display shows
Customers look at the board for a few seconds, often from across the room. Everything on it should help them find their currency and read its price fast.
- The currencies you deal in, in a sensible order. Put the ones people ask for most at the top, such as the US dollar, euro and pound, and the currencies of your customers' home countries close behind. A branch near a labour camp and a branch in a tourist mall need different lists.
- A buy and a sell rate for each. Label the columns clearly from the customer's side of the counter. Many businesses add more columns, such as cash and transfer (TT) rates.
- Flags and names, not only codes. Not every customer knows that PHP is the Philippine peso. A flag and a full name remove the doubt.
- Figures that line up. Rates with different numbers of decimals are hard to scan. A good display fixes the decimal places for each currency, or uses the same total number of digits so every figure is the same width.
- Your brand and branch. A logo and the branch name tell customers they are in the right place and make the board look like part of the shop.
- The local time and, often, a news line. A clock shows that the board is live. A scrolling line can carry opening hours, a disclaimer such as "rates may change during the day", or a promotion.
Where the rates come from
A display is only as good as the numbers on it. There are three common ways rates reach the screen.
1. Typed by hand at the sign
With older LED boards, a staff member changes each figure with a remote or keypad at the sign itself. It works, but it is slow, mistakes are easy, and with ten branches someone has to update ten signs every time the treasury moves a rate.
2. Typed once in an admin
With software-driven displays, a person enters the rates once in a web admin, and every screen that shows those currencies updates. This is the minimum you should accept today: one place to change a price, and every board following it.
3. A rate feed plus your margin
The most efficient setup reads base rates from a feed (a market data provider or a reference source such as the European Central Bank) on a schedule, then applies your own margin to produce the buy and sell figures. Your team only steps in when they want to override a price. Rate Display can read free sources from the first day and paid providers on the paid plan, every minute up to once a day.
Whichever method you use, look for a safety net. A rate that jumps 30% because of a typo or a bad feed value can cost real money before anyone notices. Rate Display asks for confirmation when a change is larger than a threshold you set (20% by default), and holds suspicious feed values for a person to accept or dismiss.
Margins and rounding
The rate on your board is rarely the market rate. It is the base rate plus or minus your margin, rounded to the number of decimals you quote. A display system should handle this for you, so that the figure on the wall is exactly what the till charges.
- Percentage margins: for example, sell at 1% over the base rate and buy at 0.8% under it.
- Formulas: for more control, a formula such as
({rate} * 1.01) + 0.02adds 1% and then a fixed amount. - Different margins by location: an airport counter and a city branch often price differently. Look for margins you can set for the whole network and then override for a group of branches or a single branch.
- Rounding once, at the end: the margin should be applied to the full-precision base rate, and the result rounded once. Rounding twice creates small differences that customers and auditors notice.
Types of exchange rate display
| Type | How rates change | Best for | Watch out for |
|---|---|---|---|
| Printed or slot-in board | By hand, card by card | Very small counters with few changes | Slow updates, looks dated |
| LED or seven-segment sign | Keypad or remote at each sign, some via a PC | Shops that want a classic look | Fixed layout, no logo or ads, one sign per currency set |
| TV with digital rate software | From a web admin or a feed, pushed live | Exchange houses, banks, hotels, airports | Needs a stable internet connection |

Who uses exchange rate displays
- Exchange houses and remittance companies: many branches, many currencies, rates that move several times a day.
- Banks: cash and transfer rates in named columns, with branch staff who should only see what they manage.
- Hotels: a calm board at the front desk showing guests the rates the hotel offers today.
- Airports and travel hubs: bilingual boards readable from across a busy hall.
- Jewellers and gold souks: visitors often pay in their own currency, and the board can show gold prices next to currency rates.
How to choose one
Before you buy a display or sign up for software, check these points:
- Live updates. When you save a rate, does the screen change within seconds, without anyone touching the TV?
- Central control. Can one person update every branch, while branch staff only change what they are allowed to?
- Rate sources and margins. Can it read a feed, apply your margins by currency, side and branch, and round correctly?
- Languages. Does it show your customers' languages properly, including right-to-left scripts?
- Design. Can you match your brand, choose a landscape or portrait layout, and keep figures legible from a distance?
- Hardware. Does it run on screens you already own, or does it need special players?
- Cost over time. Compare the up-front price of signs with a per-branch subscription, including the staff time spent updating rates.

Getting started
With TV-based software, you can have a board on the wall the same day. Rate Display needs nothing installed on the TV: each branch gets a short screen address that you open once in the TV's browser. Our step-by-step setup tutorial walks through it, from creating your company to the first live board. You can also start the 7-day trial and follow along on your own screen.
