Coupon Batches That Staff Can Actually Redeem
A coupon QR code carries the offer and a unique code in one scannable package. The customer shows it, the staff member scans it, and the code tells them exactly what to honour — no handwriting to decipher, no photocopied voucher of uncertain origin. The value of the batch stands or falls on uniqueness: if every coupon carries the same code, the offer cannot be tracked, limited, or retired, and one share online turns a local promotion into an unlimited one. Bulk generation takes a table of offers and codes and produces a set where every code is distinct, with duplicates flagged before anything is printed.
Designing codes that behave
Keep codes short, readable, and self-describing: WELCOME20 beats a random string because staff can read it back to a customer and spot a fake. Include the expiry in the payload and on the printed card, in plain words, so there is no argument at the till. Decide the redemption rule before printing — one use per code, one per customer, or unlimited within the window — and make sure the till process matches it. A unique code that nobody records at redemption is unique in name only. If you need strict one-time redemption, the printed code must be checked against a list at the point of sale, whether that is a spreadsheet or a till system.
Fraud, sharing, and honest limits
Any coupon that can be photographed can be shared, and any code that is not validated can be copied. The practical defences are boring but effective: unique codes, a stated expiry, a per-code redemption record, and terms printed on the coupon. For high-value offers, add a second check — a name, an order number, or a membership ID — so a screenshot alone is not enough. For low-value offers, accept a little leakage as the cost of doing business and set the discount accordingly. What you should never do is print an unlimited-use code for a generous offer and hope it stays local. The internet is very good at finding generous offers.
Before you print the batch
- Scan a sample coupon and confirm the offer, code, and expiry read correctly.
- Brief staff on the redemption rule and what to do with an already-used code.
- Keep the source list with the job file so redemptions can be checked.
- Print the coupon sheet and check that codes, offers, and cut lines align.
- Split lists over 500 rows into multiple batches and label each ZIP.
Coupons are promises. A batch of unique, scannable, clearly-expiring codes keeps those promises cheap to honour and hard to abuse.
