How to Write Amounts in Words on Checks and Invoices
A guide to writing money amounts in words on checks, invoices and contracts — in English and Arabic — with cents and sub-units, the “only” format and worked examples.
QR codes aren't just black-and-white squares — they're a fast bridge between the physical world and your customer's phone. Since phone cameras started reading them without apps, they've become a free and effective marketing tool for any business, from a small café to an online store. Here are ten practical uses you can set up today with our free QR Code Generator.
1. Digital menus
Put a code on each table that opens your menu page or PDF. Update prices and dishes anytime without reprinting, and save on paper menus.
2. Guest Wi-Fi
Instead of repeating the password to every customer or writing it on a board, create a Wi-Fi code guests join just by scanning. Place it on tables or at the counter.
3. Direct WhatsApp orders
A WhatsApp code with a prefilled message like “Hi, I'd like to order…” saves customers from saving and searching for your number. Perfect for bakeries, boutiques and delivery services.
4. Collect Google reviews
Positive reviews are a major factor in Google Maps visibility. Print a code that opens your review page directly and place it on receipts or the door with “We'd love your feedback”.
5. Smart business cards
Add a vCard code to your business card that saves your name, number, email and website to the scanner's phone in one tap — so your card doesn't get lost in a drawer.
6. Social media profiles
A code leading to one page with your Instagram, TikTok and Facebook links turns customers into followers instantly. Put it on bags, boxes and stickers.
7. Product info and instructions
For products that need explaining, like gadgets or cosmetics, link to a how-to video or a multilingual ingredients page instead of a paper leaflet that gets thrown away.
8. Payments and donations
Many wallets and banks offer payment links; turn them into QR codes so customers can pay or donate quickly. Always double-check the link before printing.
9. Promotions and contests
A code on a street poster leading to a discount coupon or contest entry attracts the curious and gives you real engagement data. When picking winners, use the Spin the Wheel tool transparently.
10. Inventory management
Internally, barcodes help track stock and assets. Create a Code 128 barcode for each item with the Barcode Generator and scan it by phone with the Barcode Scanner.
Essential design and printing tips
- Contrast first: dark code on a light background. Brand colors are fine as long as the contrast is clear.
- Right size: at least 2.5 cm (1 in) on cards, larger on signs scanned from a distance.
- Clear call to action: say what happens — “Scan for the menu” or “Scan to join Wi-Fi”.
- Logos in moderation: a small center logo looks great; a big one breaks scanning.
- Test before printing: scan with two different phones (iPhone and Android) and in low light.
- Print format: download SVG for professional printing so it stays crisp.
Static or dynamic codes?
Our codes are static: the data lives inside the code, so it never expires and depends on no service. Some platforms sell “dynamic” codes routed through their links to let you change the destination and track scans — but they stop working if you stop paying. Our tip: point a static code to a page on your own website and update that page whenever you like. You get flexibility without a subscription.
