BANGKOK, THAILAND — On Sukhumvit Road in Bangkok in December 2024, a vendor pointed silently to a laminated QR code while a tourist holding a Visa card hesitated. The local customers beside him finished their digital payments within ten seconds through PromptPay, Thailand’s cashless network operated by the Bank of Thailand, which logged nearly 20 billion transactions in 2023.
The invisible network behind everyday life
Introduced in 2016, the PromptPay system connects payments to ID or phone numbers instead of bank accounts. According to official data from the Bank of Thailand, every resident with a bank account can transfer money instantly with no charge for the first 30 transactions per month. On Soi Ari and Yaowarat Road, food vendors, massage shops, and taxi drivers display QR stickers that replace small change.
However, foreign tourists still cannot register because PromptPay requires a Thai bank account. ATM withdrawals at Bangkok Bank machines in 2024 cost foreign cards 220 baht per transaction, while credit card payments add another three percent fee at large stores, according to Kasikornbank fee tables published in September 2024.
App attempts to bridge the divide
In mid‑2024, TrueMoney Thailand opened its e‑wallet to tourists to join PromptPay, but registration at 7‑Eleven branches in Bangkok required multiple ID checks. Several visitors reported that deposits above 5,000 baht triggered manual review. Despite expansion promises, full functionality still depended on owning a Thai bank account.
Three start‑ups — TAGTHAi Easy Pay, Moreta Pay, and WAIWIN — entered the market between May and October 2024, each claiming to unlock Thailand’s QR economy for visitors.
TAGTHAi and its limited reach
At Suvarnabhumi Airport exchange counters operated by Kasikornbank, travelers can convert foreign currency to baht and top up their TAGTHAi Easy Pay wallets. The mobile app, promoted by Kasikornbank executives on 20 July 2024, processes PromptPay payments at registered business QR codes. Tests by users showed a 10–15% loss due to weaker exchange rates, and the inability to top up online. “THE APP FREEZES AFTER THREE DAYS OF USE,” complained a German traveller contacted in late August, who eventually reverted to cash.
Moreta Pay’s cross‑border model
Moreta Pay, founded in Singapore in 2024 by co‑CEOs Walid Mahd and Sam Yu, connects foreign accounts through Plaid integration and supports funding via Wise and Revolut. Its service claims zero transaction fees and 1% cashback, using the Google mid‑market exchange rate. On tests conducted in Chiang Mai on 10 November 2024, foreign users successfully scanned merchant QR codes in shopping malls, but not personal vendor QRs at night markets. The firm admitted technical limits, stating “PRIVATE ACCOUNT QR SUPPORT WILL BE READY IN 2025.”
WAIWIN’s early struggles
Australian‑based WAIWIN, rebranded from JamJang in October 2024, promised universal compatibility for every PromptPay QR. During field tests recorded on 5 December 2024 in Chiang Rai, several users found that loading funds required email approval and that responses from support never arrived. The App Store listed fewer than 1,000 downloads. One backpacker reported he “QUIT AFTER SEVEN DAYS BECAUSE THE TOP‑UP EMAILS WERE IGNORED.”
Why Chinese users pay effortlessly
While Western visitors wrestle with fintech experiments, Chinese tourists numbering over 10 million annually face no such barrier. On 30 October 2024, Weixin Pay signed a cooperation deal with National ITMX, allowing users from China to scan Thai PromptPay codes and pay directly in renminbi (RMB) through WeChat. Alipay, integrated since 2015 with support from Krungthai Bank and Ant International, covers more than 100,000 merchants nationwide, from Chiang Mai night bazaars to Phuket resorts.
ASEAN connections expand outward
Under the ASEAN Payment Connectivity Initiative, the Bank of Thailand enabled real‑time QR interoperability with Laos, Malaysia, Singapore, Vietnam and Indonesia. Since 3 April 2024, Laotian banking app users can scan Thai merchant QR codes. Thai travelers can also pay in Japan through the MyPromptQR system. Each cross‑border link reduces transfer fees below 1% of value compared with standard card networks.
Fees and exchange losses
Within Thailand, PromptPay transfers under 5,000 baht remain free for locals. TrueMoney, on the other hand, charges 6 baht after twenty top‑ups and 25 baht after thirty transactions, as listed on its 2024 website. TAGTHAi’s rate differentials caused losses of several hundred euros during multi‑week stays when compared to the official BOT average rate of 38.5 baht per euro. Moreta Pay currently maintains parity with that rate, according to daily figures verified on 15 December 2024.
Data privacy and user risk
Each wallet requests passport scans and selfie verification before activation. Moreta Pay stores these via encrypted servers verified by Plaid, while WAIWIN collects similar data without published certification. Security researchers in Bangkok’s Chulalongkorn University warned on 2 December 2024 that beta apps “create leaking points for personal data”.
Regulation and grey areas
Under Bank of Thailand regulations, only licensed institutions may handle baht e‑money. TAGTHAi’s cooperation with Kasikornbank ensures compliance, but Moreta Pay and WAIWIN operate as cross‑border intermediaries without domestic registration. That leaves users uncertain about refund rights. Consumer lawyers said on 18 November 2024 that disputes over frozen balances could take months to resolve.
Future prospects
Tourism contributed 12% of Thailand’s GDP in 2023, with over 35 million visitors, according to Tourism Authority of Thailand records. The Bank of Thailand has yet to announce a direct tourist version of PromptPay, but internal sources confirmed discussions of passport‑linked wallets. Until then, travelers must balance cash, cards, and app tests, remaining outsiders in a country that performs nearly 20 billion digital payments a year.
“PROMPTPAY IS EVERYWHERE EXCEPT IN FOREIGN HANDS,” a Bangkok street vendor said on Soi Nana on 7 December 2024, summing up a nation where even roasted‑chicken stalls run faster than global banking systems.
