Widely used in banking, postal, retail, securities, insurance, and communications counters
Pain point: Paper forms, difficult archiving, slow retrieval.
Solution:
ESP370U completes electronic document synthesis while the customer signs, reducing printing,
scanning, and archiving steps.
Pain point: Cumbersome signing for activation, transfer, SIM
replacement.
Solution: Electronic signatures embedded directly into business
systems, improving counter efficiency.
Pain point: Large volume of account opening agreements, insurance applications,
risk confirmations.
Solution: Original handwriting retention, encrypted
transmission, meeting compliance requirements.
Pain point: Delivery confirmation and membership registration rely on paper.
Solution:
Electronic signature pad captures signatures quickly, data returned in real time.
Pain point: Citizens repeatedly sign for social security, housing fund, etc.
Solution:
ESP370U supports domestic OS, adapts to government counter signing.
Pain point: Patient signatures and informed consent forms need long-term
retention.
Solution: Electronic archiving of signatures for easy retrieval.
