The MyCard TW Spring 2026 campaign runs February 9 to April 9, 2026 (midnight TST, UTC+8), offering up to 30% bonus diamonds on single top-ups of TWD 3,000. Credit cards and e-wallets clear in 2–5 minutes. Bank transfers can take 24 hours. With a hard deadline, that gap is the difference between 6,500 diamonds and nothing.
Why the April 9 Deadline Makes Payment Method Choice Critical
Most players treat payment submitted and diamonds credited as the same event. They're not.
When you complete a convenience store barcode payment at 11:30 PM on April 9, your transaction timestamp reads April 9 — but the batch processing cycle that actually moves funds into your MyCard Wallet may not finish until April 10. Spring 2026 checks credit time, not submission time. That distinction alone has cost players entire bonus tiers.
Spring 2026 Bonus Tiers
Bonuses are tiered by single transaction amount, not cumulative spending.
The TWD 3,000 tier is the clear value ceiling. Splitting into three TWD 1,000 transactions costs you up to 500 diamonds — the bonus applies per single transaction, not cumulatively. One large top-up beats multiple smaller ones every time.
Payment Method Speed Breakdown
Credit cards, e-wallets, LINE Pay, Apple Pay, and Google Pay are your only safe options within 6 hours of the April 9 deadline. Everything else carries real risk.
Credit & Debit Cards
Processes in 2–5 minutes under normal conditions. Taiwan-issued cards clear faster than international cards — cross-border routing adds latency, and 3DS authentication can slow things further during peak periods. The final 48 hours before April 9 will be peak.
Safe cut-off: 2 hours before midnight April 9 (10 PM TST). The 2-minute buffer is real, but give yourself room for 3DS delays.
LINE Pay / Apple Pay / Google Pay
Same 2–5 minute clearing bracket as credit cards, often faster because authentication runs locally on your device rather than through a bank gateway. Server congestion during the final 48-hour rush can add unpredictable delays.
Safe cut-off: Same as credit card — 10 PM TST April 9 minimum, 6 PM preferred.
MyCard Digital Wallet (Pre-Loaded Balance)
Pre-loading your wallet in advance is the single most reliable strategy for deadline situations. Once funds are in, redemption is essentially instantaneous — no payment gateway, no bank, no batch processing.
The optimal pre-load window is weekday mornings before 11 AM TST, when server load is lowest. Load 24–48 hours before any major event deadline. If you have more than two days until April 9, pre-load now.
Steps to pre-load:
Log into mycard.com.tw during off-peak hours
Navigate to MyCard Wallet
Select an instant digital payment method (credit card or e-wallet)
Complete 2FA OTP verification
Funds appear within 2–5 minutes
To lock in the 30% bonus without deadline stress, MyCard (TW) instant recharge before April deadline is worth checking — especially if you want to confirm delivery speed before committing to a large top-up.
Convenience Store (7-Eleven, FamilyMart, Hi-Life, OK Mart)
Works without stable internet, which makes it appealing. The trade-off: 15–60 minutes for payments before 3 PM TST, with batch processing that can push late-night credits into the next day. Minimum top-up is TWD 500.
Safe cut-off: 10 PM TST on April 8. Don't use this method on April 9 itself.
ATM Bank Transfer
Transfers after 3 PM TST can take 1–24 hours to clear — that's the official window, not a worst case. Fine for routine top-ups, but near April 9 it's simply too risky. Community experience is unambiguous: bank transfers after 3 PM TST are unsuitable within the final 48 hours of any MyCard event.
Safe cut-off: April 7 at 3 PM TST.
Full Comparison Table
All methods qualify for the same bonus tiers. No payment method gives you extra diamonds over another — what it affects is whether your top-up clears before the deadline.
Stacking Strategies That Actually Work
The 30% MyCard bonus stacks with in-game promotions, promo codes, and 2–3% credit card cashback without disqualification. Community testing confirms this.
For MLBB players: The Task Master Lucky Draw runs February 13–26, 2026, overlapping with the early Spring 2026 window. Stacking your 30% top-up bonus with that event is the highest-value play this season.
Three MLBB promo codes — 2y3vo2r3x, 0nc9lhok9, and 3r83efok9 — yield 112 diamonds combined and expire 2–4 weeks after February 9. Redeem these before topping up to shift your pity counter before spending real currency.
F2P players who stack free diamond sources before a MyCard top-up report more favorable pity outcomes. Weekly missions yield 200–300 diamonds, login bonuses 50–80, Grandmaster rank 400+. Not guaranteed math, but a widely observed pattern.
For Tower of Saviors players: The Spring Event runs February 16–March 15, 2026. At 750 points per redemption, you get 6 Diamonds + 800 Souls + 8M Coins + 1 Harpy (limit 5 redemptions). Pool all 3,750 points before redeeming — complete all five in one session rather than splitting across days.
The Safest Top-Up Strategy for April 9
Pre-loading your MyCard Wallet 24–48 hours before April 9 is the only zero-risk strategy. Everything else depends on real-time payment infrastructure during peak load.
Step-by-Step: Credit Card Top-Up for MLBB
If pre-loading isn't an option:
Visit the official MyCard payment page or your game's top-up portal
Select TWD 3,000 (single transaction for 30% bonus)
Choose credit card or e-wallet
Complete 2FA OTP — have your phone ready
Confirm transaction; funds appear in 2–5 minutes
For MLBB: navigate to the in-game top-up page, select Taiwan/MyCard, enter your serial and password
Check your diamond balance — credits typically appear within 30 minutes of redemption
One thing players consistently miss: complete full real-name verification before February 9 if you plan to top up TWD 3,000+. Verification requires name, national ID, date of birth, email, mobile, address, 2FA OTP, and a 6-digit payment password. Unverified accounts are blocked from the 30% tier entirely. Doing this during launch-day traffic means competing with support queues — don't wait.
Transaction success rate officially exceeds 99.5%. If your balance hasn't updated after 30 minutes, wait. Nothing after 2 hours? Contact support — don't discover a problem at April 9 midnight.
What to Do If Your Payment Is Pending Near the Deadline
Most guides skip this. Here's the actual escalation path.
Step 1: Check transaction status in your MyCard account dashboard. A processing status sitting more than 30 minutes on a credit card transaction warrants attention.
Step 2: Screenshot everything — transaction ID, timestamp, payment amount, confirmation screen. This is your claim if diamonds don't arrive.
Step 3: Contact MyCard TW support immediately. Don't wait to see if it resolves itself near a hard deadline.
MyCard TW support:
Hotline: (02) 2651-0754 (24/7)
Email: service@mycard520.com.tw
LINE: @mycard
Step 4: Mention the Spring 2026 event and April 9 deadline explicitly. Support agents can sometimes manually expedite processing for documented pending transactions.
On deadline extensions — community experience is mixed, and there's no confirmed policy suggesting one will apply to Spring 2026. Treat April 9 midnight as firm.

FAQ: MyCard TW Spring 2026 Payment Deadline
Does payment method affect which bonus I receive? No. The bonus is determined entirely by single transaction amount. TWD 3,000 via credit card and TWD 3,000 via convenience store both qualify for 30% — as long as the transaction clears before April 9 midnight TST.
Is convenience store payment reliable for same-day credit? Before 3 PM TST, yes — typically 15–60 minutes. After 3 PM, batch processing delays can push credits to the following day. For same-day reliability near the deadline, use digital methods.
What's the absolute latest I can top up?
Credit card / e-wallet / LINE Pay / Apple Pay / Google Pay: 10 PM TST April 9
Convenience store: 10 PM TST April 8
ATM bank transfer: 3 PM TST April 7
Pre-loaded MyCard Wallet: right up to the deadline
Can I split top-ups across methods to hit the TWD 3,000 tier? No. Three TWD 1,000 transactions each qualify for 20–25% at best — you lose up to 500 diamonds versus one TWD 3,000 transaction. Always consolidate.
What if my payment is still processing when the event expires? Call (02) 2651-0754 immediately with your transaction ID and screenshots. No confirmed extension policy exists, but documented pending transactions submitted before the deadline have the strongest claim for manual resolution. Don't wait.
Do I need verification before topping up TWD 3,000? Yes. Full real-name verification — national ID, mobile, address, 2FA, 6-digit payment password — is required for TWD 3,000+ transactions and the 30% tier. Complete this well before February 9.
Pre-load your MyCard Wallet now, use a single TWD 3,000 transaction for the 30% bonus, and don't touch ATM transfers or convenience stores in the final 24 hours. The April 9 deadline is firm, the bonus is substantial, and your payment method is the only variable still in your control.
