AIIZ and KTC have three practical routes for cardholders through 31 January 2027. Spend at least THB 1,500 in a branch for THB 100 off, or use the code AIIZKTC100 on an eligible THB 1,500 online transaction. Cardholders with KTC FOREVER points can instead register for 13 percent cash back by redeeming points equal to the transaction amount.
A third route converts a full-payment purchase of at least THB 1,500 into a 0 percent instalment plan by redeeming a set proportion of points. These options have different costs and cannot all be stacked, so decide whether immediate price, points value or monthly cash flow matters most before paying.
Take The Simple Discount
The THB 100 saving is the easiest option to understand. At exactly THB 1,500 it equals about 6.7 percent. In store, confirm the payable amount before the card is processed. Online, enter AIIZKTC100 and make sure the checkout total changes before submitting payment. Do not rely on a code entered after the order has been placed.
Consider 13% Cash Back
For the cash-back route, redeem KTC FOREVER points equal to the full transaction amount and register successfully on the purchase date. The cash back is scheduled to the card account within 60 days after month-end. Because the points cost is substantial, compare their alternative uses before choosing this route simply because 13 percent sounds larger.
Understand Instalments
A purchase of at least THB 1,500 can be converted to a 0 percent plan by redeeming points equal to 20 percent of the spend for three months, 40 percent for six months or 50 percent for ten months. Registration is required by the specified SMS or web route. Paying the balance early does not restore redeemed points.
Choose One Redemption
The points cash-back and points instalment benefits cannot be combined. If multiple registrations are submitted, KTC states that the instalment request receives priority. Check the confirmation message rather than assuming which benefit was accepted. The ordinary THB 100 shop or online discount should also be confirmed separately at checkout.
Check Eligible Cards
Several specialist card products are excluded from the cash-back benefit, including KTC CASH BACK, Royal Orchid Plus, Visa Corporate, Government Services and Thai Red Cross cards. Instalment exclusions differ. Review the live conditions for the exact card, keep the same-day registration message and retain the receipt until the benefit is complete.
