Barcode vs QR Code for Inventory: Which Should You Use?
Barcodes vs QR codes for inventory management: what each does best, what they cost, and which scanning technology fits your local shop.
Two scanning technologies, one goal
Both barcodes and QR codes exist to encode information that machines can read instantly. The question for shop owners is which one to use for inventory. The answer depends on what you sell and how much information each label needs to carry.
What a barcode is
A barcode is a row of parallel lines and numbers that stores a short code - like a product ID. It is scanned by laser or camera readers and typically holds 20-25 characters. Barcodes are the global standard for retail product labels.
What a QR code is
A QR code is a square grid of black and white squares that can hold hundreds of characters - product info, batch numbers, expiry dates, even links. QR codes are scanned by any phone camera and can carry much more data.
The price and hardware difference
Barcodes need a barcode scanner or a phone with scanning software. QR codes scan with any smartphone camera - no extra hardware at all. For a small local shop starting from scratch, QR codes mean zero equipment cost.
Speed at the billing counter
At the counter, both are fast. A dedicated barcode scanner is slightly faster in continuous scanning during a rush, but a phone camera scanning QR codes is fast enough for most small shops.
Which fits products with batch and expiry?
For food and medicine, a single barcode can only hold a product ID - batch and expiry must be stored separately. A QR code can carry product ID, batch, expiry and cost in one label, making it ideal for perishable inventory.
Printing your own labels
Both print on the same cheap thermal label printers. Whether you print barcodes or QR codes depends on what your inventory software generates and what your scanners read.
Using manufacturer labels
Most packaged goods already carry a barcode from the manufacturer. Scanning these existing barcodes saves you from printing labels for every product. QR codes are rarer on packaged goods, so you would print more labels yourself.
The best choice: use both
Modern inventory software scans both barcodes and QR codes. You use the manufacturer barcode where it exists, and print QR labels carrying full batch and expiry data for perishables. The system accepts whatever code it reads.
Example: a grocery shop decision
A grocery shop scans manufacturer barcodes on packaged biscuits and oil, and prints QR labels for vegetables and dairy that need batch and expiry info. One app handles both codes, and nothing needs retyping.
Reading codes with any device
Phones, tablets and dedicated scanners all read barcodes and QR codes. Your inventory software works with whatever device your team already has - no specialist equipment required to get started.
Mixing manufacturer and self-printed labels
Use the manufacturer barcode when the product already has one, and print your own QR label only when you need extra data like batch and expiry. The software stores both codes against the same product, so either one finds the record instantly.
Keep scanning fast with good labels
Print at the right size with clear contrast, place labels flat on the product, and keep scanning distance short. A clean label saves a second per scan - and over a busy day, seconds become minutes saved.
The future: scan anything, anywhere
Whichever code your supplier prints, your team scans with the same app - at billing, at stocktaking, at receiving goods. One habit, one tool, every code. That simplicity is what makes scanning actually stick in a busy shop.
