RFID ID Technology

RFID ID Technology

Why? How? Who uses it?

The acronym RFID stands for Radio Frequency Identification. RFID technology uses electromagnetic waves to capture and read card data. For example, an ID number is associated with a cardholder record in a system that generates transactions to open doors and track attendance for employees. These transactions allow a keyless entry option for door access to open a door and time and attendance systems to clock in for employees.

RFID chip

In most RFID configurations, the cardholders detailed information is stored in a system database. For example, a college campus student information system (SIS), and the card with embedded RFID technology emits a unique ID number to a system reader. This system reader grants or denies authentication based on the ID number matching within the related SIS database. RFID access keys that are worn for healthcare identification or school identification, as a powered ID badge, can be detected and read from a few feet away from the access point. Some RFID configurations may take advantage of the chips ability to securely store cardholder data directly for use as the source data when connectivity to the primary source database is not available. Common Access Cards (CAC) and hotel room key cards store data on the smart chips.

Magnetic strips are currently considered to be outdated technology. Barcodes have their place, however, their functionality is being absorbed by their convergence with RFID across all industries; business applications, manufacturing, healthcare systems, education, and non-profit organizations.
Barcodes once ruled employee time and attendance, however, today any new installation will either be RFID, biometric or the best of both worlds, both! For decades, RFID's proximity card dominated physical door access. However, lack of security is forcing its replacement with contactless smartcard RFID technology iClass SEOS card specs. The appeal lies in high security and additional functionality that can migrate the card to a mobile token to open doors, clock in employees, and conduct cardless/mobile POS purchases.


RFID technology is used in several ways:

ID of personnel

  • RFID technology is extremely popular in larger businesses and organizations based on ergonomics. With the mere presence of the RFID badge, it can be used to quickly identify mass volumes of authorized personnel to record time punches during peak periods. For example, during a shift change at a hospital and other time related documented transactions. RFID technology also provides the same access to security to control systems for doors and gates.RFID can also work with ingress and egress data in a government complex.Lastly, RFID technology provides ease of entry for restricted authorized personnel areas. This technology defines time zone rights and reader group restrictions.

RFID: Access to Parking Garages

Access to parking garages

  • If you work in a populated area with a parking garage, you most likely use an RFID key. When you swipe, or present the key or card near the gate, you are granted access to and from the garage. The RFID key provides a comforting and easy to use layer of security for the user.

Connectivity of both digital and physical worlds

  • RFID Clothing Tags are fantastic ways to optimize inventory control, help purchasing departments replenish inventory, provide theft protection and possess upsell opportunities.
  • For businesses, RFID tags can optimize inventory control by scanning an area of clothes to instantly find out how many of each sku they have in stock.
  • Based on sales of each sku, the businesses purchasing department can be immediately notified of what inventory is close to selling out. This lends them the opportunity to wisely purchase replenishment stock.
  • Some clothing companies fitted with RFID tags, radio signal-emitting tags, can trigger an interactive video in dressing rooms to either show the story of the product, brand, or even recommend complementary products. The video can even show size availability and where in the store the inventory exists.
  • Lastly, Clothing RFID Tags can lower theft by providing an alarm when an item isn’t purchased, yet leaves the geofence of the store.

  • So, RFID has gone mobile in more than one way, other than a stored token on your mobile device. The physical use and presentation of an ID card, photo ID badge, adhesive token, FOB, or wearable wristband form factors enabled with RFID will be present for decades to come. They all offer practical uses when generating reader-based transactions like door access, time and attendance, point of sale at transactions in one card solution, event ticketing, and event attendance tracking. Is your RFID object, or form factor, doing what you needed it to do? Consider a few generic use cases to give you some ideas.
  • Featuring Wearables: The problem today is that many people literally have their hands full when approaching a location that requires the presentation of an RFID object to open a door or record a transaction. It may be the exception; however, it is the rule for those that find it in convenient and not efficient when encountered. Imagine the ability of just waiving your arm, and the door opens, you're clocked in to work, you just paid for your meal at the café, or you just gained access to your dormitory. Going for a swim? You can gain access to the pool with your cooler in-hand, never having to manage an ID card, so you’ll never lose it. You can even go swimming with your wearable RFID. No sweat! If you're going for that mile-long jog to lose a few pounds, no longer do you have to hold your ID card in your hand. You may even work in a medical or science lab, having to carry top secret objects you just cannot put down anywhere. So, place your wrist next the reader, the door automatically opens, and your secret stays a secret; securely. Or having fun at a theme park, and the fast pass is made so much faster with the use of a wearable RFID wristband. Waiting in line is only for ticket holders, not you! Imagine how you can make your organization a more efficient space by enabling alternative RFID form factors like a wearable wristband. Imagine the possibilities!

Security of RFID Chips

Some newer debit and credit cards have RFID chips embedded inside of them, however due to security concerns and cost, most do not. RFID chips were created for security and conveniences, but unfortunately those two do not go hand-and-hand. For retail credit card transactions, rather than swiping your card, simply tap your card on the Point-of-sale (POS) device. Your card information is wirelessly transmitted to the system! This is where the security flaw comes into play.

Risk of RFID Chips

Unfortunately right after the RFID Chips were designed, hacking devices known as RFID skimmers entered the market. These devices were made to have a strong directional antenna to steal credit card info without even seeing the card! More prone in B2C card transactions than in corporate identity applications. Regardless, criminals can simply brush against you to steal your card information. Some skimmers confiscated by law enforcement have been able to skim information from a dozen yards away!

RFID Blocking

RFID: Blocking

Wallet manufacturers have started to integrate RFID-blocking technology directly into their wallets. This blocking technology is highly used in government identity projects. For example, the CAC Common Access Card, is the primary resource for photo identification in government applications. Credit card issuers will sometimes provides a RFID-blocking card sleeve. These technologies are designed to prohibit illegal wireless transfer of information, however, it is not foolproof. Newer RFID technologies are starting to use strong encryptions and 2 factor authentication. The newer RFID technologies will keep RFID cards as the most widely used embedded technology for photo identification card use.
