Read on for more details on hotel key cards, how to keep them safe during water activities, and the benefits of using RFID cards. Let’s get started!

A Brief History of the Hotel Key Сard


Hotel Keycard has a storied history, which we would like to share with you.


Back in the 1960s, when inns were still using keys as a way to enter their rooms, there was a growing problem of theft from rooms. To overcome this problem, Tom Sornes introduced the 32 holes-based plastic cards that can be used to unlock a specific lodge.

The card would allow paying guests to access their rooms while they were out. This hotel key card allowed visitors to enter their rooms without having to worry about leaving the door unlocked or feeling unsafe while they were out of their rooms.

And so the history of the hotel key card began!


The concept of hotel key cards caught on quickly, and by the late 1970s, many hotels had adopted the technology. However, it wasn’t until the early 1980s that hotel chains began implementing these systems on a large scale—and it was only then that they became an industry standard.

Swimming With Hotel Room Key


If you need to go swimming, but you are worried about getting the hotel key cards wet, don’t panic! Here’s how you can swim in hotel pools without worrying about the key.

Note: Though most hotel key cards are designed to be water-proof and won't get damaged if it gets wet, water still can damage the card's chip if it is submerged for too long. So if you are planning on swimming in the hotel pool it is better to leave it in a dry place.

Here are some places to keep your hotel key cards while swimming:

  1. You should keep your hotel key card in a secure location, such as a locked locker or a safe near the pool.
  2. But if your hotel doesn’t have one of those, then consider leaving it with the front desk or with a lifeguard if one is on duty.
  3. The best way to keep your hotel key cards safe is to use the hotel’s key holder services.
  4. If the hotel does not provide this service, consider carrying a waterproof pouch.
  5. You can also use a wristband or lanyard to attach your keycard securely to yourself while swimming.

RFID Wristband Hotel Key card- From Wallet to Wrist

  1. RFID Hotel Wristband Hotel Keycard is the most convenient way to access your hotel rooms and check out. It’s also a great way to keep track of your belongings at the hotel!
  2. The RFID Hotel Wristband Hotel Keycard is made from durable materials, so you don’t have to worry about it breaking or getting lost.
  3. RFID technology makes this hotel key card easy to use, but still secure. The RFID technology allows for quick scans of the card by any RFID reader in the area that may be used by hotels as a form of identification.

2 Key Benefits of RFID Cards Over Magnetic stripe or Barcode


Hotel key cards with a magnetic stripe are used for guest lodging access and can be kept in a pocket or in a Ziploc bag with a water bottle and swim stuff.

1. Security

RFID cards are safer than magstripe or barcode cards because of their ability to save more data and provide greater security to a transaction. This means that you can use an RFID card for transactions that are longer-lasting, such as those at your favorite coffee shop.

2. Durability & Accuracy

RFID hotel key cards can withstand more wear and tear than magstripe or barcode cards, which means they’ll last longer and be easier to read. They also have a higher level of accuracy which makes them ideal for high-value transactions.
