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.

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

3. Proposals from partner companies.

Bosch: Fingerprint door lock Renesas: RFID door lock with passive tag. eSilicon: RFID door lock with active tag.

3.1 Basic explaination of RFID technology.

Radio Frequency Identification. A micro-chip in a label used to transmit

data when the label is exposed to radio wave.

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

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.

5. Result

6. ConclusionsUnacceptable product: Fingerprint. Unaffordable Extensive maintaince InefficientAcceptable products: Active RFID and Passive

RFID. Affordable Toll-free installation Popular spare parts.

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.

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.
