@"Moonlight"#p66789 我猜海南岛应该是翻拍的时候因为光线问题没拍进去。

空白的Ntag卡片不贵，不过印刷定制之后恐怕不便宜了吧。很久以前折腾米家的时候买过Ntag卡，配合安卓App NFC Tool，折腾起来挺有意思的。

@"BG7LLA"#p66804 纸质卡是OK的，但是你的塑料卡，不仅看不见小岛，我甚至没有看见大岛...

@"Ironic"#p66805 我选的是比较便宜的一档了，价格也在1.3-1.4/张，不过印刷效果没有想象中好，感觉是色彩模式的锅，直到昨天还是前天刷文章才发现印刷最好是CYMK模式😅

地图这块很有讲究的，要注意的点太多了，一般人很难分清。简单点说：如无必要，不要放地图。

@"Moonlight"#p66809 [upl-image-preview uuid=20bfe30d-43c5-419f-997e-65a8d93fb067 url=https://storage.hamcq.cn/2025-05-23/1748011785-518623-image.png alt={TEXT?}] NFC版的QSL卡（8.5cm*5.4cm）相比于纸质版的QSL卡片（14cm*9cm）来说比较小，经过低精度的印刷和翻拍难以看见是正常的，我也检查过实体卡，肉眼是能看见的，只是不是太明显，如果对地图问题有疑问，也可以看这个电子版的图片，如果是数据源的问题，可能要向高德方面反应了，也非常感谢您的监督，维护国家领土完整是每个公民应尽的义务

@"BG7LLA"#p66819 在这里说都是OK的，但是你让那些收到卡片的同学怎么想，难不成要一个一个解释么。另外如果有外国HAM收到这样的卡片，被他小题大做一下可能会有引发国际问题的风险哦

@"Moonlight"#p66821 NFC实体卡是能看见的，NFC卡片和纸质卡片同时寄发，我会标注地图的使用源，目前只寄发国内地址国内呼号的ham

@"Moonlight"#p66821 当然，我也希望我未来有更多的预算去提升卡片的精度

Forward Statement:
1. This card is a QSL card for BG7LLA, intended solely for personal collection and purely for personal enjoyment, with no commercial intent.
2. All descriptions in this document comply with any regulations regarding radio communication in each country. I retain the right to interpret all aspects of this document, except for official descriptions, and will not individually notify you of any changes.

After a long wait, my QSL card finally arrived!

Basic introduction: Because I'm a big Harry Potter fan, I think radio waves are like magic. Although you can't see or touch them, they can connect the world, so I used a cute little Harry Potter as the main image for my QSL card.

Specifications: The NFC version QSL card uses an erasable Ntag215 chip with a memory capacity of 492 bytes. It is not pre-programmed, allowing users to erase and reprogram the cards themselves. We welcome experienced users to explore different functionalities.

The only difference between a paper QSL card and an NFC version of a QSL card is that the text on the front will be in traditional or simplified Chinese.

The NFC version has a unique identifier.

[Exchange Guide]
Method 1: Exchange QSL cards after communication.
Method Two: Request a card exchange from BG7LLA through the HamCQ community.
Method three: Send a private message to BG7LLA

Welcome everyone to exchange QSL cards!

Wishing everyone a smooth connection, 73.

The map seems to be missing some information. I recommend making changes before using it.
*There are also many inaccurate versions of maps available online. If you're unsure, it's best not to use map elements on the card.

Ironic

Moonlight I guess that "Hainan Island" was probably not filmed because of lighting issues during the remake.

BG7LLA

Moonlight 其实这个问题源自于色彩文件和打印问题，在做图的时候没有在CYMK色彩模式下做，但是背景选用了一个非常灰的颜色，对比纸质版和NFC版的QSL就能看得出来，还有就是工厂打印的精度和预算成正比，实体卡拿到手，认真看能看见南海的小岛们，至于地图的图取自阿里云DataV数据可视化平台的可视化学院，根据页面显示数据来源于高德开放平台，该版本数据更新于2021.5，仅供学习交流使用

BG7LLA
While paper cards are fine, your plastic card doesn't show either the small island or the large island...

Ironic

Blank NTAG cards are not expensive, but they may become costly after customization. I bought some NTAG cards a long time ago when I was experimenting with Xiaomi products, and they were quite interesting to use with the Android app NFC Tool.

BG7LLA

Ironic I chose the more affordable option, which cost around 1.3-1.4 RMB per sheet. However, the printing quality wasn't as good as I expected. I think it was due to the color mode settings. It wasn't until yesterday or the day before that I realized that CYMK mode produces the best results.😅

NFC version QSL card (8.5cm)5.4 cm) compared to the paper QSL card (14 cm)Considering the size of 9cm, it is normal that the printed and copied version is not easily visible due to low-precision printing. I have also checked the physical card, which can be seen with the naked eye, although it is not very clear. If you have any questions about the map, you can also view this electronic version of the image. If the problem lies in the data source, you may need to report it to Gaode. Thank you for your supervision and maintaining the integrity of national territory is a duty that every citizen should fulfill.

The map is quite complex and has many details that are difficult for most people to understand.

In simple terms: If not necessary, do not display the map.

Moonlight

BG7LLA
It's fine to say this here, but what about those who received the cards? Should I explain each one individually?
Additionally, if a foreign amateur radio operator receives such a card and overreacts, it could potentially lead to international issues.

BG7LLA

Moonlight The NFC physical card is visible, and both the NFC card and paper card are sent together. I will indicate the source of the map usage, and currently only send cards to domestic addresses with domestic call signs for ham radio operators.

BG7LLA

Moonlight Of course, I also hope that in the future, I will have more budget to improve the accuracy of my cards.

For the title section, it's recommended not to use traditional Chinese characters; it sounds strange.
Since the theme is Harry Potter, why not use English for the text, or have both English and Chinese versions? Using a map of China as the background, with Harry Potter in the foreground, creates a feeling that Harry Potter is flying on his broomstick over China and then scattering a pile of QSL cards. I think that inconsistent design elements are what make this card seem strange.

BI7DDE

@BG7LLA "#p66804 I also had my QSL card printed the day before yesterday, and I was directly asked to modify the map. It didn't include the South China Sea, so I downloaded a standard Chinese map from the Standard Map Service of the Ministry of Natural Resources and gave it to me. When printing the map for the first time, it's best to consult an experienced ham or print one out. It's easy to download maps that are missing the South China Sea, Tibet, or incorrect border lines on Baidu.

BG7LLA

BI7DDE Yes, in the next version, I will simply enhance the blue of the coastline. The main issue is that the blue coastline is too weak, especially against the gray background, which makes it appear almost invisible.

BG7NQF

The request to exchange cards within the station has been sent._{Please send a paper QSL card.}

BG7LLA

BG7NQF It seems I didn't see your application in the background.
