Shop Stamp Card and Loyalty Points Register

Shop Stamp Card and Loyalty Points Register is an offline app (one HTML file in a zip) that replaces paper stamp cards. You list your members, define your own rewards and the points they cost, and record each purchase. The app works out points, keeps every balance, refuses a reward the member cannot afford, and shows who is ready to claim, who is a few points away and who has stopped coming.

The problem it removes: Paper stamp cards are lost, stamped twice, stamped without a purchase or claimed from memory. The shop cannot say how many points are owed to customers, who is close to a reward, or which regular has not visited for months. This app keeps a single balance per member that staff can check at the counter, with every point traced to a dated entry.

What is inside:

• Members with numbered cards, phone, join date, spend, visits, points balance and days since the last visit
• Two ways to earn, set in Settings: points per AED spent, or one stamp per visit above a minimum spend
• Rewards you define, each with its own points cost, which can be switched off when withdrawn
• Point entries for purchases, rewards claimed, bonuses and corrections, with rules that stop a reward the balance cannot pay for
• Today page: rewards ready to claim, members a few points away, and members not seen for the number of days you set
• Printable loyalty card with the balance and the reward list, and a printable points statement for a member
• Example data you can load in one click, a Start here guide and an Honest limits panel
• JSON backup and restore, CSV export, and CSV import with a check of every row before anything is added

Who it is for: cafes, bakeries, salons, barbers, gift shops and any small business that gives stamp cards or points to repeat customers and wants a balance it can trust.

What it is NOT: It does not read a till, scan cards or link to online orders: a person enters each purchase. Points do not expire by themselves, and it does not set the value of a point or the terms of your scheme. It sends nothing automatically and is not a customer database for marketing consent. It is not legal, tax or accounting advice, it is not connected to any government system, bank or messaging service, and it does not file or send anything by itself. UAE e-invoicing is not part of it.

Verified by us: scripted tests in Chromium (103 checks through the real screens: adding, editing and deleting records in every table, required-field messages, backup then clear then restore, CSV export then import, keyboard order, print layouts rendered to PDF, no horizontal scrolling at 375 and 1280 pixels, no network requests) and an independent recalculation by a separately written Python evaluator of 726 calculated values (25 randomised rows plus the example data) with 0 mismatches. Not tested: Safari and Firefox beyond what is stated here, and no real printer was used (print layouts were checked as PDF).
