Why AI couldn't identify an item
Automatic skip rules
Rasmerk's scanner automatically skips lines that match:
- Payment/summary keywords: Total, Subtotal, Cash, Change, Visa, Mastercard, Amount, Tender
- Tax lines: CGST, SGST, IGST, GST, Tax, Tip (these are extracted separately)
- Receipt metadata: Date, Time, Table, Waiter, Cashier, Receipt, Invoice, Bill
- Contact info: Phone, Mobile, Tel, GSTIN
- Thank-you lines: Thank, Visit
Lines where the item name is shorter than 3 characters are also skipped.
Common OCR failures
- Faded thermal paper — text is light and ML Kit misreads or skips it.
- Crumpled receipts — curved text creates bounding-box confusion.
- Dot-matrix or handwritten receipts — not well-supported.
- Phone number on receipt — 8+ digit sequences are filtered as phone numbers.
Fixes
- Try Improve with AI mode — AI can handle more ambiguous text.
- Add the missing item manually after scanning.
- Retake the photo in better lighting.
