- 2. RFID in Forensics How does it work? Where can it be used in
the forensic sector? What are the benefits? What is the future?

- 3. RFID vs BAR CODE Is possible to attach a tag on many
surfaces No line-of-sight requirements Can be reprogrammed in the
field to reflect current information, i.e. sample status and
location. Low Cost: 0.25 Now everything has a bar code Requires
line-of-sight Only ID information Data is fixed at the moment the
label is printed Cost free - relatively RFID BAR CODE Forensic Expo

- 5. What is RFID? RFID = Radio Frequency Identification An RFID
tag is an object that can be applied to or incorporated into a
product, animal, or person for the purpose of identification using
radiowaves. Some tags can be read from several meters away and
beyond the line of sight of the reader. Forensic Expo

- 8. Components and types of RFID tag Antenna: for receiving and
transmitting the signal Integrated Chip Plastic Inlay TYPES
Passive: no battery, the electrical current induced in the antenna
by the incoming radio frequency signal provides just enough power
in the tag to power up and transmit a response Active: internal
power source, which is used to power the integrated circuits and
broadcast the signal to the reader Semipassive: similar to active
tags in that they have their own power source, but the battery only
powers the microchip and does not broadcast a signal. Forensic Expo

- 9. TAGS: Different Types Active RFID Tags. These tags are
battery powered in order to transmit a signal to a reader, and are
generally used for high-value goods that need to be tracked over
long ranges. Passive RFID Tags. These tags are not battery powered,
and instead draw power from electromagnetic waves given off by an
RFID reader. The read range for passive tags is usually under three
meters. HF Tags work at 13.56 MHz and are passive They have no
built in power source 28/04/2014 Forensic Expo 2014 Combine RFID

before they died. See Guidance note 6 for more information. The
consent form is important as a record of consent given. The
completion of the form is just one part of the consent process.
Full explanation of the PM examination procedure along with
discussion and time for reflection by those consenting, are equally
important. Individuals and relatives should be able to discuss this
process fully and ask any questions. Staff seeking consent for PM
examination must be trained in how to obtain valid consent. Consent
is only valid if proper communication has taken place.
Consideration should be given to the needs of individuals and
families whose first language is not English. The consent form
covers consent for the PM examination itself as well as for the
retention and use of organs and tissue following the PM
examination. *If you modify this form, please remove the HTA logo.
Format of the form Please note that there are three sections to
this form. This form is produced as a Word file. You can edit the
yellow shaded sections to make them appropriate for your Trust.
Guidance notes, available at the end of this form, are also
indicated by yellow shaded sections. They offer extra guidance and
some suggest text that you might like to consider inserting,
according to local practices. If you are having the form printed
professionally, you may wish to consider producing it as a
three-page booklet with duplicate copies. Consent for post-mortem
examination of an adult Name of deceased: Date of birth: Date of
death: Consultant / GP in charge of the patient: Hospital number

have taken Hair, Blood , Oral and Urine samples for use in
Childcare cases involving drug or alcohol misuse for over 20 years.
One of the key issues in any legal case is ensuring that the Chain
of Custody is maintained. Using a 3G enabled tablet PC, our
collectors are sent the location and details of the sample
collection . Tablets are GPS enabled and linked to Google Maps.
This means collector can find the site, and we also know where they
are! We are also able to use the camera to verify identity .
- 67. 0330 1000 747 The USB RFID reader, eliminates the finger
trouble of entering the unique serial number of the sample taken.
Tamperproof security seals are then attached The Donor confirms the
RFID number on the tag is the same one automatically read Using the
touch screen, the donor signs the tablet and the sample envelopes.
The Electronic CoC is then sent to both receiving lab and our
office

suitable for extremely small items or tag dimensions. Scan angle.
Barcodes require line-of-sight scanning, without obstructions. Tag
orientation. Barcodes require line-of-sight scanning. You cannot
read them through objects, paint, mud or dirt. Harsh environments.
Barcodes can be scratched, scuffed, or corroded. Abrasion and
direct impacts deface barcodes. Bright sunlight and reflective
surfaces. Ice and Water droplets. 28/04/2014 Forensic Expo

- 77. TAGS: Different Types of chips The microchips contained
within RFID tags can be identified as read-write or read-only.
Read-Write RFID New information can be added to these chips, or
existing information on these chips can be written over when the
chip is within range of a reader. Laboratory test results and
sample status can be frequently updated. Sample location included,
chain of custody, evidence rooms etc. Read-Only RFID Generally less
expensive than read-write tags, but still contain a UID. The Unique
Identification is the most important feature of the tag. (Source:

- 78. TAGS: Different Types (and Costs) Active RFID Tags. These
tags are battery powered in order to transmit a signal to a reader,
and are generally used for high-value goods that need to be tracked
over long ranges. Passive RFID Tags. These tags are not battery
powered, and instead draw power from electromagnetic waves given
off by an RFID reader. The read range for passive tags is usually
under three meters. 28/04/2014 Forensic Expo 2014
