Terms of Use
ภาษาไทยThe Checkslip service (the "Checkslip system") is a service for checking bank transfer slips through an API on checkslip.com and any other channel the Company may add later. It is provided by บริษัท โฮโลแกรม จำกัด ("Checkslip", the "provider" or "we"). These terms set out the duties and responsibilities of Checkslip and of the user of the service (the "user" or "you"). By signing up for, using or reaching any part of the Checkslip system, you accept these terms and the laws that apply. If you do not accept them, please do not use the service.
1. Definitions
1.1 The "service" is fetching whether the bank holds the transfer on a slip: you send a slip image or the QR data on the slip through the API, and the system returns the result and the transfer details. It includes the account pages for checking credits and usage history.
1.2 A "user account" is an account a person or a company signs up for to use the service.
1.3 A "user" is a person or company that signs up for an account in their own name, in a company's name, or as an authorised representative.
1.4 An "API key" is the code the system issues for calling the API of that account.
1.5 A "credit" is the unit used to check slips, one credit per slip, obtained by buying a package.
2. The service
2.1 Checkslip is software that helps you check slips. You connect the results to your own website, app or chatbot.
2.2 Selling goods or services to your customers is your own responsibility. Checkslip only helps you check slips, and you will not claim from Checkslip for damage caused by your goods or services.
3. Sign-up and packages
3.1 Signing up with an email on the website is free; you must verify your phone number before buying a package. The information you give must be true.
3.2 A new account gets the free Tester package of 50 slips, once per mobile number. It has no cash value.
3.3 The service is sold as credit packages, paid once, with no monthly fee and no automatic renewal. Prices are as shown on the website and exclude VAT (the Company is not yet VAT registered).
3.4 Credits can be used for 1 year from your most recent purchase. A new purchase adds the new credits to the old ones and restarts the 1-year period. Expired credits are lost in full.
3.5 One credit is taken only when the bank finds the transfer and its data is fetched. No credit is taken when the transfer is not found, for a duplicate slip already looked up, while waiting for the bank, when the bank cannot be reached, when the QR cannot be read, for a damaged file, for a QR whose check value does not match, for a slip older than the look-back period, or when Checkslip's own system fails.
3.6 When credits run out or expire, the system stops returning results until you buy more. You are never charged beyond your package.
4. Payment and credit top-up
4.1 Pay through Stripe by card or PromptPay QR, or any other channel the Company sets.
4.2 Once you pay, the system adds the credits to your account and you can see your balance on your account page. If the credits do not arrive, send the proof of payment and your account email through LINE OA @checkslip.com; the team will check and add them within 1 business day.
4.3 A receipt is issued for every payment and sent by email or LINE OA · tax invoices can be issued only after the Company registers for VAT, and cannot be issued for earlier purchases · companies may withhold 3% tax (not needed for amounts under 1,000 baht) and send the 50 Tawi certificate through LINE OA or email.
5. Closing your account
5.1 You can close your account at any time through LINE OA or your account page. It takes effect at once.
5.2 After closing, the Company keeps account data for no more than 6 months and then deletes it, except documents that accounting and tax law require it to keep. Lookup history data encrypted with the account's key is destroyed the moment the account is closed; the bank's answers kept for a while stay for no more than 90 days, as section 8 of the Privacy Policy states.
6. Refund policy
6.1 Package fees are not refunded in any case, including credits left when an account is closed or suspended.
6.2 Paying twice or paying too much by mistake: the excess is refunded or turned into credits, as you choose, within the time the team tells you.
6.3 A fault in Checkslip's own system that takes a credit without a real check: the credit is given back.
7. Use of the service
7.1 Only users with an account may use the service.
7.2 You must keep your password and API keys secret and never put them in front-end web code. If someone else uses them, that counts as your use and the credits taken are not returned. If you think a key has leaked, ask for a new one at once.
7.3 Do not copy, take apart, reverse engineer, modify or interfere with the system.
7.4 Do not infringe Checkslip's copyright, trademarks or other intellectual property. If you do, the Company may end the service and take legal action.
7.5 You set up and maintain the API connection in your own system. The team can advise, but is not responsible for your system.
8. Prohibited use
8.1 Do not resell, rent out or share API keys with others without written permission.
8.2 The service may not be used for these businesses: gambling of any kind · drugs, cigarettes and tobacco products · weapons · pornography or illegal goods · trading crypto or digital assets · any other activity that is illegal under Thai law.
8.3 If the sign-up details are false, the service is misused, sections 7 and 8 are broken, or your system puts the service at risk, the Company may suspend or close the account at once without refunding fees, and you are responsible for the actual damage caused, including damage to third parties.
9. Changes to the service and these terms
9.1 The Company may update the system from time to time to make it work better.
9.2 Changes to these terms or to package prices are announced at least 30 days ahead on the website and LINE OA. Credits already bought can be used under the old conditions until they expire.

As set out in the Privacy Policy and the Data Processing Agreement (DPA) in the Privacy Center · the Company does not keep slip images.
11. Limitation of liability
11.1 The service is provided "as is" and "as available". Results rely on data from banks or payment providers, which may be delayed or inaccurate at times, for example during bank maintenance. Use results as one input to your decision.
