The document evaluates proposals from three companies for an RFID door lock system for a bank building. It analyzes the proposals based on cost, maintenance, security, and efficiency. The evaluation finds that the active RFID system best meets the criteria, being more secure and efficient while still affordable. It is recommended to purchase the active RFID locks to ensure safety of employees and property within the budget.

3. 1. Introduction
 Evaluating proposals from Bosch, Renesas,
eSilicon.
 Introducing our method of evaluation to
select the suitable product.
 Representing the most feasible solution for
our company.

4. 2. Background
 Vietcombank
building in Danang.
 Present situation:
obsolete and unsafe
office doors.
 Implementation of
secure and reliable
door locks. Figure 1. Vietcombank Building in Danang

5. 3. Proposals from partner
companies.
 Bosch: Fingerprint door lock
 Renesas: RFID door lock with passive tag.
 eSilicon: RFID door lock with active tag.

6. 3.1 Basic explaination of RFID
technology.

 Warning light

11. 4. Method
 Bought sample equipments from each
candidate.
 Tested samples in 3 rooms in our
building.
 Assessed performance of sample
products based on 4 criteria:
 Cost
 Maintenance
 Security
 Efficiency

12. 4. Method (cont’d)
 Evaluating criteria:
 Comparison in cost between 3 samples
 Comparison in time periods of
maintenance between 3 samples.
 Comparison in security between 3
samples.
 Comparison in efficiency (reaction ability
to external impacts) between 3 samples.

17. 6. Conclusions
Unacceptable product: Fingerprint.
 Unaffordable
 Extensive maintaince
 Inefficient
Acceptable products: Active RFID and Passive
RFID.
 Affordable
 Toll-free installation
 Popular spare parts.

18. 6. Conclusions
 Regarding acceptable the two models:
Active RFID and Passive RFID
 Active RFID technology meet superior
criteria:
 Higher levels of security and efficiency.
 Meeting cost criterion.
 Ease of use.

19. 7. Recommendation
 Recommending purchasing Active RFID door
locks.
 Ensuring the safety of our properties and
employees.
 Investing in Active RFID door locks within our
budget (needing $4050 out of $5000)
 Being total responsible for our judgement and
selection.
