Description

Prepaid meal coupons, issued in books and redeemed at the till.

  • CouponBook (book number from Admin's canteen-coupon-book sequence, purpose, department, cost centre, quantity, value, price list, valid till) and its Coupon rows.
  • CouponCodeGenerator: CP-0914-0001-K7 shape, a check character that catches every single-character typo, alphabet excludes I, L, O, U.
  • GET coupons/resolve?code= -> valid / expired / redeemed / void / book closed.
  • POS Coupon tab: the coupon covers up to its value, any remainder is cash. Redemption marks the coupon under a row lock, inside the same transaction that numbers the sale.
  • A void un-redeems the coupon; two concurrent redemptions of one coupon settle to exactly one success; closing a book voids only the unredeemed coupons.
  • /coupons page with an issue dialog and an A4 print sheet (3x7 cut-outs, barcode).
    Depends on: Admin's coupon-book number sequence.
