6.7. SAM (Secure Access Module) Support
The VP7225 includes 4 SAM slots to enhance security for sensive operaons. It communicates with
SAM cards in pass-through mode.
6.7.1. Performance Tip for SAM Transactions
Please note that the best way to optimize performance is to minimize the number of APDU
exchanges, even if combining all operations into a single exchange is not feasible.
Reducing the frequency of APDU calls helps lower communication overhead and shortens overall
transaction time, especially critical in time-sensitive applications like fare collection or contactless
payments.
6.7.2. Installing SAM Cards
• SAM slots are located on the back of the device.
• Please insert or remove SAM cards only when the device is powered o to avoid hardware
damage.
6.7.3. Protocol and Communicaon
• Supported Protocols: ISO/IEC 7816 T=0 and T=1, depending on the card ATR.
• Maximum Baud Rate: Up to 125.1 Kbps.
• Clock Frequency: 4.002 MHz.
• The reader supports a wide range of TA1 conguraons for compability with various SAM cards.
* Note: For compatibility verification with custom or non-standard SAM cards, please contact IDTECH
technical support.
6.7.4. SAM Command Set
The VP7225 supports low-level ICC commands, enabling direct APDU communication with chip cards:
• The Pass-Through Mode Start/Stop (2C-01) command enables pass-through mode for direct
SAM card communication. You must issue this command before the reader can process any SAM
commands. This command also terminates pass-through mode.
• The Get ATR (2C-12) command activates the ICC and establishes a Layer 1 session to retrieve the
ATR.
• The Exchange APDU Data (2C-13) command exchanges APDU data with the SAM card.
• The Contact Transacon Power O (2C-18) command powers o the SAM card. When a
transaction is successful, the ICC slot or SAM needs to power off before the user removes their
card.
6.7.5. Example SAM Operaon Flow
1. Use the Pass-Through Mode Start/Stop (2C-01) command to enable SAM card access. You must
issue this command before sending any APDU commands.

6.9. Installation Checklist
When installing VP7225 units, be sure to verify the following items.
6.9.1. Visual Inspection
Before installing a VP7225:
• Visually inspect the reader for any modifications on the plastic housing.
• Check the security labels over the screws to verify the reader has not been tampered with.
• Power up the reader and check for any flashing LEDs and beeps that indicate tampering. Refer
to Tamper and Failed Self-Check indicators for specific information.
6.9.2. Installation Procedures
After visually inspecting the VP7225, follow these guidelines when integrating the reader to your
system:
• Insert any Security Access Modules into the SAM sockets.
• For additional memory expansion, insert any microSD card into the uSD socket.
• If your unit supports LTE radio, insert your network SIM into the SIM sockets.
• Close the cover and install the unit in its housing using four screws. Note: Do not overtighten
the screws.
• If the display module is supported, insert the display module flex into the optional LCD
connector.
• Insert the communication/power cable into the USB-C connector and tighten the locking screws
(if provided).
• Power on the whole system and check the unit’s operations.
6.9.3. Recommendations
Additionally, follow these recommendations after installation:
• Periodically inspect the system for any tampering and insertion of electronic bugs.
• Look for the latest updates on the manual or firmware on the ID TECH website.
VP7225 User Manual
Page | 34
• See the Installation Points, and Firmware Upgrade sections below for additional information
about verifying device functionality and performing maintenance.
6.10. Using the VP7225 to Make a Purchase
The section below provides instructions for making purchases with the VP7225.
6.10.1. Presenting Cards or NFC Phones
The VP7225 allows for credit/debit card purchases using Contactless (NFC) technology.
Present the card/phone in close proximity to the front portion of the antenna module. Present the
card/phone so that maximum surface area is parallel to the antenna module as shown below.
The antenna should beep, and the four green LEDs should illuminate in sequence, then all will illuminate
together, briefly (750 msec), to indicate a successful test.
This tests the VP7225’s ability to read the Contactless test card. If unsuccessful, there will be no reaction
from the reader. If you use a test card and the VP7225 antenna is attached to the VP7225 Controller, a
dummy transaction can be tested. The transaction will not be authorized and will come back with a
response but will at least test for end-to-end connectivity.
VP7225 User Manual
Page | 35
6.10.2. Making a Purchase
After the transaction has been entered on the kiosk control panel, the customer should present his or
her card/fob/phone in close proximity with the device so that maximum surface area is parallel to the
antenna.
• A single beep and all four LEDs briefly flashing indicates the card/fob/phone has been read
correctly.
6.11. Installation Points
• The VP7225 is NOT designed to be mounted on a metal surface and in close proximity to any
internal motors and electrical devices that may be operating inside the kiosk. However, the
VP7225 is susceptible to RF and electromagnetic interference. It is important that the unit not
be mounted near (within 3 or 4 feet) large electric motors, computer UPS systems, microwave
transmitters (Wi-Fi routers), anti-theft devices, radio transmitters, communications equipment
and so on.
• Close proximity of metal to the RF-emitting end of the antenna can greatly reduce the range of
the antenna. See the precautions described in Flush Mounting the VP7225 Antenna.
• Make sure to install the SAM/SIM card cover before checking SAM/SIM cards functions.
• Tie all cables neatly with nylon cable-ties and route them so that they are inaccessible and
invisible to customers. Label the cable ends, host, ID TECH and power, to simplify connection
testing or component replacement.
• Test the VP7225 installation using a test card to perform an end-to-end transaction (the same as
an actual purchase on the Kiosk). The kiosk display panel (if it exists) should display "Requesting
Authorization." Even if the transaction is declined (as it should be with a test card), it will prove
connectivity all the way through the system. If possible, the store manager or some other
responsible party should test each VP7225 on a regular basis (perhaps at the start of each day or
at least once per week) with a test card to ensure continued operation and functionality. If the
kiosk is rebooted on a regular basis (such as every night), it is important to test the contactless
reader as soon as possible afterwards to ensure continued communication to the kiosk host.

8. RF Interference
Q. Why do I need to know about RF interference?
A. Contactless payment uses radio frequency technology to send card data to a contactless terminal
reader.
Q. How can RF interference affect contactless payment?
A. RF interference can cause data errors. If RF interference is present, contactless payment devices may
operate intermittently or inconsistently.
Q. Where does RF interference come from?
A. Radio frequency interference (RFI) can originate from a wide number of sources at the point-of-sale
(POS). Some examples of sources of RF energy and RF interference include:
AM/FM radio and TV transmitters 2-way radios, pagers
Mobile telephones Power lines, transformers Medical equipment Microwaves
Electromechanical switches
Q. What should I do if I suspect RF interference exists in my environment?
A. Begin by inspecting your environment for possible sources of RF interference.
Q. Do equipment manufacturers test their devices for RF interference?
A. Electronic equipment is tested for RFI sensitivity by the manufacturers. These tests are performed in a
controlled laboratory environment and will often not replicate the types of devices that would be
encountered in your point-of-sale (POS) environment.
Q. What RF levels will impact RF operations?
A. Factors that can cause RF interference vary case-by-case. There are no set rules defining a single RF
level that will cause RFI. RFI depends on the sensitivity of the equipment under consideration, or how
low an interfering signal can be in the presence of the equipment and cause problems.
Equipment can be particularly sensitive to very low signal levels of one frequency and yet be quite
immune to high signal levels of another frequency - so frequency is an important factor. Some electronic
system components are internally shielded and have a very high immunity to interference; but
generally, most equipment has not been so engineered.

12. Avoiding Device Tamper Issues
All ID TECH PCI-certified devices integrate tamper switches and disable the card reader when it has been
compromised. The section below describes best practices when handling PCI-secure devices to help
prevent triggering the tamper switches.
Note that following these guidelines does not guarantee a device will not tamper if inadvertently
mishandled or breached. User-induced tamper events will incur repair fees, key injection fees, and
shipping both to and from ID TECH, regardless of warranty status.
12.1. Device Handling Best Practices
• Do not excessively shake the reader.
• Do not drop the reader.
• Do not strike the reader.
• Do not attempt to twist or cause any torsion to the reader.
• Do not expose the reader to extreme heat or cold.
• Do not intentionally subject the reader to electrical shocks.
• Do not submerge the reader in liquids of any type for extended time.
• Do not attempt to open the reader.
• Do not provide power to the reader until all connectors are plugged into the unit.
• Check the device manual to ensure the reader receives the correct power voltage. Providing
power to wires and connectors before plugging them into the device may cause power spikes
that can trigger a tamper event.
• When working with or installing the reader, minimize exposure to static electricity.
12.2. ID TECH Support
In the event the reader does tamper when under warranty, report the tampered device to ID TECH
to troubleshoot and, if needed, be returned to ID TECH for analysis. Contact ID TECH support
at [email protected] for assistance.
