LINE slip-check bot: how it works in a group (2026)
Shops that sell through LINE groups, such as regular-customer groups, reseller groups or order groups, often get many slips at once. Admins switch to the bank app and compare each amount by hand, which gets slow and error-prone as orders grow. A slip-check bot checks each slip as soon as the customer sends it. This article explains how the bot works and what to look at before choosing one.
What is a slip-check bot
A slip-check bot is a LINE bot in your group or chat. When someone sends a picture of a transfer slip, the bot has it checked and answers in the same chat, so the shop knows whether the money arrived without opening the bank app.
What the bot reads from a slip, and how it catches fakes
Transfer slips from Thai banks carry a QR code with the transaction reference. Easyrobin reads this QR and checks the transaction with the bank directly, so the amount, sender, receiver and time the shop sees come from the bank, not from the text on the picture. Editing the numbers on the picture does not change the result.
When a picture has no QR code, the system treats it as an ordinary photo and says nothing. If the QR code can't be read, the sender is asked once for a clearer picture.
The answers the bot gives
- Money received: the bank found the transaction and the amount and receiving account match the shop
- Checking: the bank has not found the transaction yet; the system checks again several times within 15 minutes
- Duplicate: a transfer the shop has already counted from another slip, or one already used at another shop
- Failed: for example no transaction found, the receiving account is not the shop's, or the amount does not match
- Below minimum: less than the minimum the shop set for that channel
- Needs a check: the system cannot decide and the team looks, for example the same slip sent again before the first one is counted
Link the slip-check bot to your shop's LINE group
- In Easyrobin's slip check page, add the bank account or PromptPay the shop receives money on
- Add Easyrobin's slip-check bot as a LINE friend and invite it to the group
- The bot sends a card to link the group to the shop. A business owner or manager who is in the group taps it and picks the business. Working on a computer? The slip check page shows a code to scan or type on the phone
- Once linked, anyone in the group can send slips. The bot answers quoting that picture and tags the sender; an album of several pictures gets one combined answer
The bot reads slip pictures and messages in linked groups so the shop can check slips and reply. It does not answer general chat, but the shop's team sees it in Easyrobin's chat page. People in the group who are not on the shop's team, such as customers, cannot link the group to a business of their own.
Works with your LINE OA chats too
Besides LINE groups, Easyrobin checks the slips customers send in the shop's LINE OA chats too. The result sits on the slip picture in the chat and in the slip check page with a daily summary. The shop chooses which results the customer is told in the chat and which only the team sees; a new shop starts with the team only.
What to check before choosing a slip-check bot
- Does it check with the bank? A bot that only reads the text on the picture is fooled by edited slips
- Does it catch duplicates, both a slip sent again and a slip already used with another customer
- Does it check the receiver's name and account, so the money really went to the shop
- If the bank has not found the transaction yet, does it check again by itself or must an admin press a button
- Is there a history for the team and a daily summary
- How is it charged? Easyrobin counts only slips the bank found; see each plan's slips on the pricing page
A bot takes most of the comparing off your hands, but it still pays to know how fake slips look. Read our article on spotting fake slips, and see the details of Easyrobin's slip check on the automatic slip check page.
