Validation by Automated Visual Cheque Scrutiny

Robotic Signature Verification

Signature Mandate Rule Validation

Key Information Extraction

Extracts Handwritten &
Printed English Texts


  • Recognizes & Verifies signatures including validations against signing power mandates
  • Extracts, Transforms & Interprets printed and handwritten text information using Deep Learning Robotic elements specifically trained for Cheques
  • Performs authenticity checks based on – Logo, MICR Band, Endorsement Stamp, Account Payee Stamp, Crossed Cheques
  • Identifies strikeouts, overwriting, damage, mutilation, white ink/oil/water marks on Cheques
  • Detects absence of mandatory information like date, signature etc.
  • Equipped with configurable validation engine capable of performing technical validations required for an Inward Clearing Cheque Scrutiny
  • Every Robotic Extraction, Verification and Validation is supported by justification and audit trail logging


Dexter Checker Queue (DCQ)

Supports incremental manual processing of failed Robotic validations and also provides conservative manual checker scrutiny for High Value / High Risk Cheques

Unknown Language Queue (ULQ)

Supports manual processing of non-English language cheques

Dexter Guided Queue (DGQ)

Provides for continuous On-The-Job Feedback training to robotic elements within Patterns Dexter

Quality Control Queue (QCQ)

Provides random selection and human quality control check of cheques automatically cleared by Dexter


  • Symbol Identification Process – To recognize symbols specifically used by customers while writing their cheques
  • SEAM – Signature Extraction and Matching Algorithm
  • Traversal Algorithm – To separate the overlying objects in cheques
  • Cheque Approved Signatures (CAS) enables a mechanism of continuously replenishing customer signatures to record variations over time, facilitating tracking and automated addition of new specimen signatures
  • Audit Trail & Justification Log – Maintains log for all robotic decisions including the verification of signatures (Signature Justification Log Images)
  • Dexter Robotic Call Back – To secure customer confirmation before execution of a payment transaction
